Temperatures shifting all around and some howling winds.......a neighbor's large cardboard box got blown into our yard, so I saved it on our deck until garbage collection day. In the meantime, it snowed, then rained, then got freezing again. This is what collected, with a little manipulation ~
Temperatures have warmed up so the ice and snow has melted and revealed the sand, along Tiscornia Beach.
After overnight temperatures dropped to -8deg C, December 1st 2019 yielded a perfect, windless winter day in the Northern Fells. Merchant Navy Class 35018 "British India Line" passes Salterwath in great style with the second "Santa Special" of the season, hauling a 13 coach load, plus train heating diesel loco. This situation happens only rarely!
Even though the temperatures here are now becoming noticeably more spring-like, I still need to include a few winter photos. But don't worry, there aren't that many.
After that, I can fully dedicate myself to spring.
You recently saw a small glimpse of this enchanted forest. Here's another overview.
Auch wenn die Temperaturen hier nun beginnten deutlich frühlingshafter zu werden, muss ich trotzdem noch ein paar Winterbilder unter bringen. Doch keine Sorge. Es sind nicht so viele.
Danach kann ich mich dann voll und ganz dem Frühling widmen.
Ein kleinen Ausschnitt dieses verzauberten Waldes habt Ihr vor kurzem schon einmal gesehen. Hier ist nochmal ein Gesamtüberblick.
Subzero temperatures greet us each morning now, and the trees are heavy with hoar frost. Pastel colors sweep across the sky and reflect from the snow. When Doc Doolittle went out to feed the birds this morning - I spotted this gray jay as he made his way to the feeders. Doc and I had just enjoyed a pancake and sausage breakfast and the left overs were on the menu for the jays. They all fight to be first, because they want the meat - the slower ones end up with pancakes. As the old saying goes; "the early bird catches the worm" - or in this case, "the sausage".

The Galápagos penguin (Spheniscus mendiculus) is a penguin endemic to the Galápagos Islands. It is the only penguin that lives north of the equator in the wild. It can survive due to the cool temperatures resulting from the Humboldt Current and cool waters from great depths brought up by the Cromwell Current.
While ninety percent of the Galápagos penguins live among the western islands of Fernandina and Isabela, they also occur on Santiago, Bartolomé, northern Santa Cruz, and Floriana. The northern tip of Isabela crosses the equator, meaning that some Galápagos penguins live the northern hemisphere, the only penguins to do so.
The species is endangered, with an estimated population size of around 1,500 individuals in 2004, according to a survey by the Charles Darwin Research Station. The population underwent an alarming decline of over 70% in the 1980s but is slowly recovering. It is therefore the rarest penguin species (a status which is often falsely attributed to the yellow-eyed penguin).
Population levels are influenced by the effects of the El Niño Southern Oscillation, which reduces the availability of shoaling fish, leading to low reproduction or starvation. However, anthropogenic factors (e.g. oil pollution, fishing by-catch and competition) may be adding to the ongoing demise of this species. On Isabela Island, cats, dogs, and rats attack penguins and destroy their nests. When in the water, they are preyed upon by sharks, fur seals, and sea lions. – Wikipedia
As did the Orange-crowned Warbler. Overnight temperatures gradually warmed up somewhat from yesterday's minus 28 windchill and stand at minus 6 (wc minus 15) this morning. Both birds were seen this morning feeding frequently on grape jelly. This seems to be the preferred food even though there is peanut butter suet and mealworms there for them.

Kurondo-ike Pond is my usual walking route. It's located about 10km north of my place and has a high altitude, so the temperature is a little cold. To me, this year's cherry blossoms looked sharp and firm.
On the Saturday I flew from Reykjavik up to Akureyri for a few hours, up in Iceland's frozen north, just below the arctic circle. The temperature here was -14C (6F), and sunset at this time of year is at 14.40hrs. As you can see the seawater in the fjord has almost fully frozen over.
High body temperatures can be dangerous and lead to some odd perceptions of reality.
Fever is a sign of inflammation, and it’s part of the body’s immune response. It’s often accompanied by chills and sweating. Some people also experience disorientation, strange dreams, seizures, and hallucinations with a fever.
On their own, fever hallucinations themselves aren’t dangerous, even though they can be frightening.
Temperature up 7 to 14 the next tree days that will destroy the ice and snow.
Spring now - March to May. This is when snow begins to melt and it gets warmer.
Often birds on ice, and I took a picture of a couple here, view below….
At this moment in our area it is -9F ((-23 C) with a "wind chill temperature" of -30F (-34C) !!
I remember the warmth of Sanibel Island last February. This picture shows what my PoV will be very soon...
... I lift my head from the chaise on the beach, take a cold sip, listen to the shorebirds squawking in the soft breeze, smell the Gulf of Mexico, and see the gently swaying palm trees...

Quintessential Fall
It’s midday at milepost 69 on the Portland Sub, the temperature now peaking into the high 40s, just enough to make up for the stiff breeze in my face. Low, broken clouds and an aqua-blue sky scream Pacific Northwest during the fall, the fractured cloud ceiling behaving rather favorably for mid November, putting me on the winning side of what is almost universally a losing battle with the weather gods. It’s only about 20 minutes or so after solar noon, the sun sitting just a few ticks above 20 degrees on the horizon, a far cry from the nearly 65 degrees it would be suspended at right now during the summer solstice.
In addition to the favorable weather, the train counts are solid. It’s once again reasonable to expect about a train an hour on the Oregon side of the river, a drastic difference to what was observed just last year. With 6644 out of the way, it is now CP 8948’s turn to run the 22.2 mile section of effectively single track from Meno to Crates. It’s 9.5 miles in so far and will continue rolling along for another 33 miles before coming to a stop at Biggs, the destination for day 6. Until tomorrow.

It was sunset time at Gunstock Mountain. Temperature was very low (wind chill below 0 degree F) that I could not exposure my hands very long. Looking at the sunset, I felt and dreamed of the warmth.
Temperatures are now significantly below zero, Sunday it was frosty in combination with sunshine. A great time for hiking in the Vennebeck area, Ostwestfalen, Germany
cold temperatures and blue hour twilight combine to give the ice on the tittabawassee river a jade green tint that contrasts with the layers of the orange and purple sunset
Temperature was about -17F with wind chills near -40F this morning and the lake was steaming just after sunset. It was so cool. This picture does not do it justice. Enjoy
Three weeks ago we had our first severe winter storm of the year. We received 9.4”. The following Thursday we received 6.7” then yesterday we received sleet and ice, quite thick. So ready for winter to be over!! Photos are out my backdoor along my bluff and backyard. Photo images credited to Vickie L Klinkhammer of Vickielynne Photography and Designs (VLP&Designs).

The temperature was already a balmy 87 degrees when I started my short walk into Bushey Point at Leesylvania State Park early on a summer morning. The air, as it has been all of the month of July, was already thick and heavy by the time the early morning northbound parade began on the RF&P. I135, stacks from Suffolk to Chicago, almost always has the power from I136 when it gets spun. Knowing this train would have 2 MACs, and a fresh leader, it was a nice easy decision on what train to chase this day. The bridge over Powell's creek is easily the best vantage point for good power on morning northbounds, and despite having shot many trains here through the years, still my favorite spot to sip coffee and watch em roll by. Being as busy as the RF&P is, it's tough getting everything north in the VRE rush hour windows. Somehow, BD manages to make it happen, and 135 rolled through at track speed with a hot train en route to Cumberland from Acca Yard for their crew change.
When temperatures dip below freezing, Frostweed (Verbesina virginica, Asteraceae) the sap in the stems expands due to freezing temperatures, and the stem cracks. Once exposed to the cold air, this water freezes into delicate ribbons of ice, creating stunning “frost flowers” or ice sculptures. These formations appear early in the morning and melt as the day warms. This usually only happens with the first frost of the season.

Temperature just around zero degrees Celcius.
Hair ice (also known as ice wool or frost beard) is a type of ice that forms on dead wood and takes the shape of fine, silky hair. It is somewhat uncommon, and has been reported mostly at latitudes between 45 and 55°N in broadleaf forests. The meteorologist and discoverer of continental drift, Alfred Wegener, described hair ice on wet dead wood in 1918, assuming some specific fungi as the catalyst, a theory mostly confirmed by Gerhart Wagner and Christian Mätzler in 2005. In 2015, the fungus Exidiopsis effusa was identified as key to the formation of hair ice.
Formation
Hair ice forms on moist, rotting wood from broadleaf trees when temperatures are slightly under 0 °C (32 °F) and the air is humid. Each of the smooth, silky hairs has a diameter of about 0.02 mm and a length of up to 20 centimetres (7.9 in). The hairs are brittle, but take the shape of curls and waves. They can maintain their shape for hours and sometimes days. This long lifetime indicates that something is preventing the small ice crystals from recrystallizing into larger ones, since recrystallization normally occurs very quickly at temperatures near 0 °C.
The hairs appear to root at the mouth of wood rays (never on the bark), and their thickness is similar to the diameter of the wood ray channels. A piece of wood that produces hair ice once may continue to produce it over several years.
In 2015, German and Swiss scientists identified the fungus Exidiopsis effusa as key to the formation of hair ice. The fungus was found on every hair ice sample examined by the researchers, and disabling the fungus with fungicide or hot water prevented hair ice formation.[1] The fungus shapes the ice into fine hairs through an uncertain mechanism and likely stabilizes it by providing a recrystallization inhibitor similar to antifreeze proteins.

Cheveux de glace
Les cheveux de glace, ou chevelure de glace, sont le phénomène d'apparition de glace sous forme de filaments très fins, par temps de gel, à partir de morceaux de bois mort ou d'autre végétaux. Le phénomène est comparable mais distinct des pipkrakes, issues du sol et plus grossières. Les cheveux de glace sont différents du givre par leur apparence comme par leur formation.
Formation
La formation des cheveux de glace se produit dans des conditions météorologiques particulières : par gel modéré et lorsque le sol, très humide, n'est pas encore gelé. Le phénomène est rare et s'observe plutôt dans les sites ombragés et tôt le matin.
Les cheveux de glace apparaissent sur des végétaux particuliers, comme le bois mort de hêtre ou de chêne. Leur observation donne à penser que l'eau contenue dans le bois est expulsée à travers les pores du bois par son expansion à l'approche du point de congélation, et gèle sous forme de fils très fin au contact de l'air. Le mécanisme pourrait néanmoins être plus complexe et être lié à la présence de champignons sur ces bois en décomposition; en 2015, le champignon Exidiopsis effusa (en) a été identifié comme essentiel à ce mécanisme. La poussée de ces fils de glace peut avoir une force suffisante pour repousser l'écorce d'un bois mort. La formation est très fragile, elle se détruit au toucher ou au souffle et disparait naturellement par fonte ou sublimation si elle est exposée au soleil.
Historique
En 1918 Alfred Wegener évoque que le mycélium sur le bois en décomposition contribue au phénomène. En 2014, Christian Mäztler, physicien de l’université de Berne associé à Diana Hofmann, chimiste et Gisela Preuss, biologiste ont élucidé le mystère de leur formation.

Haareis, manchmal auch Eiswolle genannt, besteht aus feinen Eisnadeln, die sich bei geeigneten Bedingungen auf morschem und feuchtem Totholz bilden können. Anders als Hydrometeore (zum Beispiel Raureifkristalle) entsteht Haareis aus dem im Holz enthaltenen Wasser, nicht aus Luftfeuchtigkeit.
Ähnlich aussehende und häufig nicht genau unterschiedene Phänomene sind Bandeis (engl. ice ribbons, ice flowers) an Pflanzenstängeln und Kammeis (engl. needle ice) am Boden, die beide jedoch anders gebildet werden.
Entstehung
Wissenschaftlich ist die Entstehung des nur selten zu beobachtenden Haareises noch wenig erforscht. 1918 beschrieb der Meteorologe Alfred Wegener Haareis auf nassem Totholz. Er vermutete einen „schimmelartigen Pilz“ als Auslöser, was jedoch von anderen Wissenschaftlern angezweifelt wurde, die rein physikalische Prozesse wie bei der Entstehung von Kammeis als Ursache annahmen.
Eine biophysikalische Studie von Gerhart Wagner und Christian Mätzler bestätigte 2008 Wegeners Vermutung weitgehend. Demnach wird Haareis durch das Myzel winteraktiver Pilze (u. a. Schlauch- und Ständerpilze) ausgelöst, deren aerober Stoffwechsel (Dissimilation) Gase produziert, die das im Holz vorhandene leicht unterkühlte Wasser an die Oberfläche verdrängen. Dort gefriert es und wird durch nachdrängende, beim Austritt aus dem Holz ebenfalls gefrierende Flüssigkeit weitergeschoben. Dies geschieht ausschließlich bei Temperaturen knapp unter dem Gefrierpunkt, wenn das Wasser im Holz noch nicht gefroren ist, es an der geringfügig kälteren Umgebungsluft jedoch gefriert. Eine Randbedingung für die Haareisbildung ist außerdem hohe Luftfeuchtigkeit: Wenn die Luft nicht mit Wasserdampf gesättigt ist, sublimieren die feinen Eiskristalle kurz nach ihrer Bildung an der Holzoberfläche, so dass keine langen Haareiskristalle entstehen können. Eine Reproduktion von Haareis ist in Versuchen solange möglich, wie das Pilzmyzel im Holzkörper nicht abgetötet wird.

Nighttime temperatures dropped to 25 F, but the morning temperatures were climbing quickly as the colors slowly changed in the cottonwoods.
This is a working ranch, with some historical items, some new, all serviceable. The blue flatbed truck gets special care, and is referred to as "Mr. Jones."

Our daily average temperature has been dropping since July and hit rock-bottom a few days ago. Today the tide turned and we inched up a degree if this were a "normal" year. To celebrate, here's a look back at those balmy summer days. The orange sulphur is sometimes called the alfalfa butterfly because its caterpillars like to eat alfalfa leaves. However, the caterpillars also eat the leaves from a variety of other legume plants. Females have light-colored spots that break up the solid black bands that form a border on their dorsal wing surface, visible in this backlit view. Male orange sulphurs would be all black along that wing border.
