The sun bear can be found in tropical forests of Southeast Asia. It is the smallest species of bear, with a length of up to 5 feet and weighing up to 150 pounds. This small size facilitates their arboreal lifestyle of moving about amongst the trees. Despite their name, sun bears are actually nocturnal, roaming the forests at night.
Their fur is mostly black in colour apart from a crescent-like golden patch on their chest. According to legend, this patch resembles the rising sun, hence the name ‘sun bear’. Their coat is well adapted for the tropical rainforest as it is short enough to prevent overheating but is thick and coarse enough to protect against branches and rain.
09-September-2022: this is the third Local Severe Thunderstorm, which forms directly above the sea surface of the Gulf of Trieste, in just 12h.
The sea is charged with heat (potential energy) as early as April and until mid-August, when the air heat remains strong, but the sun loses power, lower on the horizon, with fewer hours of sunshine and longer nights, therefore not able to keep the waters so warm.
At this point, after having accumulated for months, the sea begins to gradually release the heat (and humidity) which transforms the troposphere into a pressure cooker (Cape Index); the arrival of the first real Atlantic fronts, with fresher air, are the spark and exploit the energy involved, transforming it into severe thunderstorms.
The transfer of heat, from the overheated North Adriatic to the atmosphere, is particularly strong between late August and mid October, then becomes progressively less intense with a more decisive cooling of the local shallow waters, but continues on a larger scale involving the whole Mediterranean, where the heat continues to be released into the atmosphere very decisively.
The complete period of maximum atmospheric liveliness in the Northern Mediterranean area - late August/mid December - over the years, is becoming the only sort of "rainy season" of the 4 that occurred at this latitude - 45° North.
The others have often become the domain of the African anticyclone which can do nothing only in autumn when atmosphere "explodes".
In any case, the Mediterranean and the Eastern Atlantic have the potential to still affect all seasons, given their waters remain mild and active even between winter and spring, although the energy involved is lower and this helps African HP to take root by stabilizing the weather for long periods, even 15 consecutive months as happened between June 2021 and August 2022, when not even in autumn it was possible to exploit the summer potential, but the latter situation is to be considered an exception and not a trend.
The trend is to no longer have 4 moderately (or intensely as in the south-eastern Alps) rainy seasons, but 3 mainly dry and only one rainy peak, in autumn.
Evidently it is a form of tropicalization of the Mediterranean area where it happens that even large accumulations of energy may not be sufficient to create thunderstorms and rains, as is always the case in these "new" Mediterranean summers characterized by oppressive heat and the presence of almost constant sun.
In autumn, the atmospheric liveliness manages to move HP and bring the Atlantic and Arctic fronts to the fore with often spectacular'n'dramatic consequences.

01-september-2022: there is a need for a certain quiet although this photo still demonstrates how energy is abundantly present in the atmosphere even in inland areas and without solar ground overheating.
The cloudy veils called "Pileus", that envelop this cumulonimbus cloud in full phase of development, are (basically) orographic lenticular clouds, where the Cumulus, of which they are accessory clouds, represents a sort of mountain which with its ascent generates, around itself, condensation and solidification of water vapor into these horizontal clouds (made up of ice crystals), a bit like what happens around real mountains when humidity increases and temperatures decrease.

26-May-2022: we have entered the season of heat thunderstorms that in the afternoon and early evening vent an accumulation of heat, the result of the solar overheating of the previous hours, and moisture, coming from the Adriatic as a sustained breeze.
The pre-Alps, like the Dinarides watershed ridge, force these flows to rise and condense into clouds with vertical development, or thermoconvective.
The clouds in the photo have a strong double-cell thunderstorm, with torrential rain, but without hail, as happens when the "Cumulonimbus" does not pass to the "Incus" phase.
Anvil towering cloud represents the maximum development of these clouds, whose cauliflower ("calvus"), by freezing first and for having reached the limit of the troposphere then, wears out in a capillary way ("capillatus") and tends to widen horizontally, as well as being more easily moved or curled (ice crystals lightness) by the prevailing wind.
GSW-Hochhaus, since 2017: Rocket-Tower
mirrored in a car
"The GSW Headquarters in Berlin by Sauerbruch Hutton is designed with a low energy concept and uses systems of ventilation, heating, and lighting in order to reduce the energy consumption.
The solar shading system and the solar flue were designed with the use of the computational fluid dynamic (CFD) analyses which allowed for the room temperatures throughout the year to be observed. The west façade of the building consists of three layers that create the solar flue. The colored panels on this side of the building can be opened and closed by the occupants in order to let in or shut out light; however, they can also be controlled by management in order to prevent overheating. The east façade of the building consists of two layers, creating a buffer, and is ventilated on each floor."

"It is a crystal which captures light during the day and which, at night, appears like a signal or a lighthouse"
Architect Giovanni Vaccarini
«C'est un cristal qui capte la lumière la journée et qui, la nuit, apparaît tel un signal ou un phare»
Since the renovation of its head office, SPG has reduced its energy consumption by 60% per heated square meter and by 50% in electricity by installing a thermal envelope made up of 2,900 glass slats of different length, thickness and depth.
"It is a crystal which captures light during the day and which, at night, appears like a signal or a lighthouse".
The heating and ventilation system have also been completely redesigned by the architectural firm Giovanni Vaccarini.
The cooling is done statically from the ceiling. The cold air descends slowly, and the heat emitted at the foot of the facade, by ejectors send the preheated air into the rooms.
The facade is made up of triple glazing with high performance thermal insulation, as well as single glazing provided with ventilation slots placed in front of blinds with micro-perforated slats. These provide protection against direct sunlight as well as comfort. visual. Single glazing also contributes to solar reflection. A silver coating on one side of the glass prevents any overheating phenomenon. The last elements are the solar shading glass slats fixed to the facade by reinforced aluminum forks. They are studded with multiple small dots that enhance solar protection while letting the light diffuse very softly inside the building.

Here I am about 20 linear km north-east of Trieste and at an altitude of 870m on the Mount Vremščica ridge-plateau (the summit is 1026m a.s.l., while in front you can see the soft Slatina pre-peak, 929m a.s.l.),
Vremščica divides the Coastal Karst (Primorska in Slovenija and Trieste Karst in Italia) from the Internal Karst-Dinaric Region (Notranjska, Slovenija).
On this Karst moor (gmajna) it rained in the afternoon and now the weather is more stable.
With the sun hidden, isolated patches of fog form from saturation of the water vapor due to the cooling of the ground.
Radiation fog is an opposite phenomenon to the one that is developing (in the sky) in the direction of Ljubljana, where, unlike here, the previous sunshine has overheated the ground activating updrafts and the formation of towering clouds with a heavy thunderstorm forming.
.....not only because of self-destruction,
it will also feel better for everyone
if we stop burning our planet all the time.
I think we covered the game with fire,
and many haven't even noticed.
Fire is a very powerful element, it can bring light
or the hell.
We got enough better Alternatives,then the fossil Combustion.

UP 1943 crawls east towards Donner Summit on a cold October evening. The third unit had overheated and when the train was put into full throttle it started giving a really nice smoke show. The train would halt at the summit and sat for hours before finally making its final miles over the summit and down to Sparks.
The sun remained at its peak. Why does this single hour feel like an eternity? She leaned agaisnt a parked cab, that was overheating slightly from being out in the sun for a while. Perhaps the cab driver was having his lunch, probably taking a nap and she came up with plenty other scenarios in her head since she had the time to imagine.
A soft purr and furry brush agaisnt her arm shook her thoughts slightly. Her hand reached out to stroke the cat that decided to keep her company. She reached for her phone with her other hand, reading the message to make sure she didn't get the time wrong.
In fact she came on time and now it had been an hour since the agreed meeting time. Maybe she should just leave? Or maybe she should wait? What a dilemma, she could have explored other parts of the city in that one hour or got some ice cream, VANILLA~ to quench the heat a bit.
Sometimes, seconds turn into minutes, minutes turn into hours, hours into days and days into weeks... before she realizes it, a year has passed by and she always wondered how did it zoom by without giving her a chance to even clutch into every moment, every memory, make it last a bit longer, treasure it.
After all, time doesn't really make a difference. Someone you have known for 7 years could easily ghost you and someone you have just known for 7 months is always there for you no matter what.
"I could wait forever, or chose to direct my time towards something worthwhile..."
And that is how I made more meaningful connections...
P.S. Lya and Adam created a beautiful home called Whisper City. I did some night time photos around which will eventually turn into day too of course through the story. Just check out the album for more and more. ;)
This American Avocet is an example of that elegance as it quietly moves across the water at Bear River Migratory Bird Refuge, Utah.
American Avocets place their nests directly on the ground without the benefit of shrubs to provide shade. To keep the eggs from overheating during incubation, they dip their belly feathers in water. (CornellLab)
An image previously posted as a square crop has now been rescanned and reprocessed in its original 24x36 format. While the square version arguably made for a better composition, I think this wider view gives it more room to breathe and offers a bit more interest, especially as it's now coming up to 45 years old.
The train, a 3-car class 506 unit with M59401M leading, is seen here on the approach to Hadfield station where it will terminate. Originally ordered in 1938 by the LNER, the eight sets comprising the class weren't built until 1950 and would enter service in 1954 on the then newly electrified Woodhead route serving the Manchester - Glossop - Hadfield section. While technically they could run all the way over the Woodhead to Sheffield, in practice they were rarely seen east of Hadfield where the challenging gradients coupled with their low gearing rendered them prone to overheating. (Info courtesy of Wiki).
Interestingly these units, built by Metropolitan Cammell and BRC&W, would outlast the class 76 and class 77 locomotives. They were withdrawn in 1984, three years after the Woodhead route closed east of Hadfield, when the remnants of the line were converted from 1500v DC to 25Kv AC operation.
This shot was taken on a cold and misty late autumn morning with the sun just starting to break through. The orange-vested trackside chaps had been giving the point some attention - it was an important one too seeing as all trains terminating at Hadfield used the crossover to access what was the Down mainline back to Manchester.

Dragonflies can be seen to point their tails vertically (like an obelisque) in very hot weather. It is thought to help them reduce overheating.
On what appears to be the last run of their type, Wessex Electrics 2415 and 2420 pass Kings Langley on their final journey from Bournemouth to Wolverton.
73128 'OVS Bullied C.B.E' brings up the rear, while out of sight at the front are 73107 'Tracy' and, providing traction, 66722 'Sir Edward Watkin'.
In service from 1988, the Wessex Electrics spent their years operating from Waterloo to Weymouth, then from Victoria to Gatwick and Brighton, and finally from Waterloo to Portsmouth and Poole.
Although they appeared to have a future, delays in their latest refurbishment programme and the drop in demand caused by the Covid-19 pandemic caused their final refurbishment to be cancelled.
Between May and July the survivors were hauled from Bournemouth to Wolverton for stripping prior to scrapping. This was the last of those moves.
The need to convey a partially refurbished fleet from Bournemouth to Wolverton for stripping created some challenges which led to the strange formations used for these hauls.
The refurbishment including replacing the ancient English Electric 546 DC traction motors with new AC motors. At the same time, the BR southern region EP braking system was removed and replaced with a 3 stage electrical brake system. Only 3 of the surviving units retained DC traction motors and EP braking when the decision to terminate the refurbishment was made. For these drags to Wolverton, one of the these units, No 2420 was retained to act as a 'fitted head', with each AC-fitted unit effectively being unbraked.
The class 73/1s also support the EP braking system and so were necessary to operate the brakes on 2420. Complicating the issue, some of the units had bent buffer stalks so the class 73/1s were also acting as barrier vehicles. This also facilitated the reversal at Branksome to reach Bournemouth depot. Thanks to www.flickr.com/photos/linesidephotos21/ for this information.
The use of the class 66 was not strictly necessary - in theory the class 73/1s should be able to use their 600hp engines to power the train away from the 3rd rail. However, the class 73s have a long and illustrious history of overheating when operating away from the 3rd rail. On one of the runs to Wolverton on 5th July no class 66 was used and predictably the class 73s overheated, resulting in a class 56 stepping in. After that event, a class 66 provided traction for the remaining runs.

They seemed confused, stressed and overheated from the hot weather unsure whether to cross the highway. Taken from my truck, not because the bighorn sheep were dangerous because the traffic was. Unreal, if you pull over off the highway immediately 5 cars stop all around you despite a raging semi truck and oncoming traffic. It is crazy out there! Don't know how the bighorn sheep survive it. Nice of them to give me a good backdrop for my quick click.

Colour graded re-edit of a shot from July 2018. Good news - my PC is having a water cooling system bypass operation with a new one transplanted tomorrow and, thankfully, no damage appears to have been done to the motherboard or chips from the cooling failure and overheating. It will be back soon!
I hope you enjoy this one. Stay safe!

I had actually taken a pic of my hand cupped around the sun...but, unfortunately they did not come out as I had planned...in addition to my laptop overheating...I had to simulate my NOVA idea...in processing...
Birds will pant, sort of like a dog when they get too hot, which is exactly what this trip-colored heron is doing. Got a bit winded and overheated during a quest for breakfast? Or just a morning workout?

Arizona Central's classic power set pulls 21 coal loads out of Drake and into the canyons towards Perkinsville. The power set consists of an ex-SP GP9R, TPW GP7, and a chop-nose GP7 courtesy of Santa Fe, the previous operator of this branch. Some of the engine compartment doors are left open for most of the runs to prevent overheating, not something to complain about when you can shoot such an incredible power set in 2021!
30-June-2019: these background large storm cells do not draw energy from the Northern Adriatic, they are, instead, much more far multi-cell storms originated by the heat of the overheated solid soil of the Alps...and what Alps!!
At that time, the multi-cell thunderstorm on the right poured torrential rains and hail in the Dolomites of the North-East Alto Adige (Südtirol for German speaking), extending beyond the Italian State border, in Tirol, Austria: it is an area distant from the Gulf of Trieste 250 to 300 linear kilometers!
The air masses at high altitude were generally dry and extremely transparent.
The cell on the left, on the contrary, is in an advanced phase of dissolution, but it is precisely the residual fresher air generated by the previous thunderstorms that keep the right cell still active (after having even generated it a few hours before), despite the setting of the sun.
While in the area to photograph the Cape Breton & Central Nova Scotia we lucked into the startup of the Windsor & Hantsport Railway. They had recently took over operation of the lines operated by CP subsidiary Dominion Atlantic (DAR). They started with a small fleet of former CP RS23s, or ugly 8s as they were known. To keep from overheating, they all faced west to keep the radiators facing into the direction they operated with the loaded trains.

See notes.
More than the wide 360° view (except 30° from antennas and radars, which hide the Kamnik Alps in North Slovenia), the massif itself is very interesting (for me...) from a micro-climatological point of view.
In particular from a rainfall point of view, Učka represents an extreme example of self-production of clouds and precipitation.
No other isolated relief of the entire area that I follow comes close to what Učka produces only for itself!
Detached from the most important "precipitation basin" of central-northern Dinarids (Gorski Kotar, HR/Snežnika, SLO: up to 3000mm or 3000l/m2 per year), it rises on a less rainy area, going from 1100/1300mm per year downstream in 3 out of 4 directions and around 1700mm/year towards the North, in the highest section that connects it to Ćićarija, its peak reaches 2500mm per year, which shows how it "does everything by itself"!
The particular precipitation regime is clearly due to the orography of a isolated mountain, as well as to the geographical position where various currents meet and go up again from various directions, this means that the summit is a point/line of convergence (the summit is on a small north-south ridge) and as such it generates clouds and precipitations forming an orographic low pressure (causes updrafts that reduce gravitational pressure) just above it.
Wet and mild air ascends it from the south-eastern side (that in the shot), where it rises imperious (considerable prominence) directly from the sea of the Kvarner Gulf, moreover warmer and drier air, during the day, with solar overheating, climbs it from the Istrian side, the south-western one, in particular from the Čepić basin (in the previous photo), while colder currents can be added from the north
The air that rises up the slopes meets progressively colder masses and this leads to the condensation of the water vapor in clouds, while the continuous ascent of the currents gives the clouds a marked vertical development, especially between spring and summer with the formation of thunderstorms exclusively along the its slopes and on its top.
In these cases the altimetric thermal gradient is very marked and contributes to generating and reinforcing the phenomena.
Even the individual fronts are evidently emphasized by the ascent to which the currents that accompany them are forced by the marked orography of the massif in every direction.
It is a rare thrill to come across a 'valezina' type of female Silver-washed Fritillary. Valezina famales were once thought to be confined to the New Forest but are principally found from Dorset to the west Weald of Surrey accounting for between 5% and 15% of female Silver-washed Fritillaries. This beautiful valezina flew across my path before settling briefly at the back of a shadier bramble patch in my local Hampshire wood, her exquisite upperwings showing the characteristic dusky greenish sheen. Their avoidance of sunny clearings and rides and preference for shady woodland may, it is suggested, (Thomas & Lewington : The Butterflies of Britain and Ireland) be because they are more prone to overheating. In accordance with this theory, it was also a cloudier day when I saw this one flying.
Vie bactérienne autour d’un geyser
Les sources chaudes peuvent abriter des archéobactéries résistantes à la chaleur et au manque d'oxygène. Les couleurs rouge, jaune, bleue et verte des bassins thermaux, les filaments blancs ou les structures brunes et gluantes entourant la mare d'eau chaude d'un geyser sont constitués d'organismes thermophiles ou de cyanobactéries, vivant dans l'eau soufrée et surchauffée.
C'est dans les années 1960 que les scientifiques purent démontrer l'existence de ces archéobactéries : Thermus aquaticus par exemple, décrite par Thomas Brock en 1969. Cette découverte a démontré le rôle joué par les cyanobactéries dans l'apparition de l'atmosphère terrestre.
Bacterial life around a geyser
Hot springs can harbor archaebacteria resistant to heat and lack of oxygen. The red, yellow, blue and green colors of the thermal pools, the white filaments or the brown and sticky structures surrounding the pool of hot water of a geyser are made up of thermophilic organisms or cyanobacteria, living in sulfur water and overheated.
It was in the 1960s that scientists were able to demonstrate the existence of these archaeobacteria: Thermus aquaticus for example, described by Thomas Brock in 1969. This discovery demonstrated the role played by cyanobacteria in the appearance of the Earth's atmosphere. .
HEAT afternoon THUNDERSTORMS
16-June-2019: on the Karst Region, generally, after a sunny and very hot morning, the first clouds (Cumulus humilis and mediocris into Cumulus congestus) form around 10AM Central European Time, while the spark that ignites the first, fundamental, thundery heat (Cumulonimbus), takes place between 12AM and 1PM CET; the ingredients for the formation of this type of local storms, in these parts, are always the same: (1) rapid solar heating of the soil and air layers above it, and, from mid morning, (2) very humid breezes coming from the Gulf of Trieste (Italy) and, for the more eastern areas, also from the Kvarner (Rijeka, Croatia).
The thermodynamic ascension of the summer sun overheated air, whose condensation into towering stormy clouds is widely favored by maritime humidity added, is necessary, although not sufficient, in producing fuel for these "internal combustion engines".
In general, after the first thunderheat, many more are formed and, in a important part, this happens thanks to the first one: the cold part of the thunderstorm, where there are precipitations and cool descending currents (Downdraft), becomes seed for the "burst" of other storms in the vicinity, with a chain effect.
This happens because the downdraft cool air, when it reaches the ground, turns into a horizontal wind, fresh and very humid, which with its rabid gusts moves away from the original storm in many directions, reaching areas still sunny, then causing the immediate, forced, rising of the hot air present (lighter than the fresh one arrived) condensing into new clouds with vertical development, base for further heat thunderstorms, at least until the sun warms the soil.
2019 West-Tsavos National Park, Kenya
. These antelopes have beautiful, large, dark eyes surrounded by a white ring. And while their eyes are stunning, they provide more than just sight. Preorbital glands appear as a black spot below the inside corner of each eye. These glands produce a dark, sticky secretion used to scent-mark their territories.
The most distinguishing feature is their elongated snout, which is also an evolved cooling mechanism that stops them from overheating, even in extreme temperatures of up to 40°C (104°F). This also helps minimize their need for water.

Here I turned 180° in the opposite direction to that of the thunderhead in the previous photo, i.e. from the Internal Karst (East) towards the Coastal one and Trieste gulf (West, see the notes), which City is partly covered by the Trieste Karst plateau itself from this POV.
You will all have noticed that in summer, after a sudden and short rain water vapor rises from the ground, which was overheated by the previous insolation, and condenses into "smoke".
The phenomenon is mostly visible on the asphalt, without wind and generally lasts a tens of minutes.
If sunset is near and the sun no longer dries or heats the ground, therefore remaining cooled and made humid by the rain, thanks to the physiological drop in temperature in the evening, the air saturated with water vapor condenses into low mists (and rapidly into dense fog) in the more humid, low-lying and flat or concave areas.
Areas with these characteristics, such as the widespread Karst-Dinaric region basins, have a more marked drop in temperature especially near the ground, in open areas, mainly grasslands and moors.
The fog that form is therefore close to the ground (generally from it for a few tens of centimeters and up to 4-5m in height) and stratified; if the sky remains clear and without wind, thermal inversion fogs last all night and dissolve only with the direct sunrays of the following morning.
Here is a shot of the 1966 Lola Chevrolet T70 Spyder (chassis SL71/35) in the assembly road during the very wet Saturday of the 2016 Goodwood Revival.
Originally bought for AJ Foyt and paid for by Goodyear, it raced three times in its debut year at Riverside and Nassau, but retired due to overheating issues at each event. The car then became stripped for parts over the following years, before being bought and rebuilt by specialist Lilo Buzieron who returned it to 1966 FIA specs.

A rather overcast Llandudno Bay this morning. Taken just before Sunrise in the drizzle.
Llandudno in the winter has a certain charm. Its not as busy, the hotels are dirt cheap(but kinda dirty!) and you get the winter weather.
We spent a few hours on the Saturday evening taking photos and heading up the pier for a celebratory mulled wine. Sunday morning was supposed to be an epic sunrise from the top of the Great Orme. The reality, low cloud, full on drizzle, 11c and we were dressed for 0c! With the risk of overheating and damp lenses we gave up and kept to the lower levels.

15-April-2023
Cold air at high altitudes and overheating of the ground by the (previous) sun generated intense thunderstorm activity in the cores of which a phenomenon was formed which many, by approximation, mistake for hail.
The formation of granular snow/snow grains (or white hail) is all in all similar to that of hail but occurs in clouds mainly composed of ice crystals and not water droplets as typical in spring with thermal 0°C at relatively low altitude.
The updrafts of the "hot part" of the Thunderstorm, which feed the cell, carry/drag humidity and ice crystals (droplets in the case of hail) upwards which compact to form little balls, grains or rice of snow covered with a thin film of black ice, which then fall by gravity from the cold part of the storm (downdraft) where rainfall is concentrated.
What is evident for those who have witnessed both phenomena (the "pure" hail here occurs only in summer in case of heavy thunderstorm) it is the specific weight of the individual snow grain and hailstone, the former decidedly lighter and slower in falling, the latter much harder, compact and faster (and much less white), which can cause serious damage as opposed to the harmless white hail.
Naturally, like everything in meteorology, the clear classification of the phenomena is only formal and concerns the 2 extremes, in reality there is a considerable variety of nuances in the relationship between water and snow to compose the solid precipitations described.
in fact, I overheated today.
yesterday was a two tick day, both in my hair.
I'm hitting the shower tonight to wash any away.

Exhibiting an “open door” policy most likely caused by overheating on a warm May day, Santa Fe SD45R 5329 leads a westbound train drifting downgrade out of Bealville.
This was a tough night. Shot in the Pinto Basin (near the "car wash") of Joshua Tree National Park (an area best avoided in the summer months), my camera sensor overheated and I had very few usable photos, despite a perfectly clear, dark night... excellent conditions for shooting the Milky Way. This image is a composite of the old rusty vehicle remains (image 1) and the Milky Way sky (image 2, taken later that same evening). HSS!!
