Quite a lot of convection yesterday afternoon, with rapidly changing cloud forms. I snapped this and the shot next door from a nicely elevated railway footbridge.

I used Yukon Gold Potatoes for this dish. I baked them in my Convection oven so they would come out crispy on the outside and soft on the inside.

The Sun is a G-type main-sequence star comprising about 99.86% of the total mass of the Solar System. It is a near-perfect sphere, with an oblateness estimated at about 9 millionths,which means that its polar diameter differs from its equatorial diameter by only 10 km. As the Sun consists of a plasma and is not solid, it rotates faster at its equator than at its poles. This behavior is known as differential rotation, and is caused by convection in the Sun and the movement of mass, due to steep temperature gradients from the core outwards. This mass carries a portion of the Sun’s counter-clockwise angular momentum, as viewed from the ecliptic north pole, thus redistributing the angular velocity. The period of this actual rotation is approximately 25.6 days at the equator and 33.5 days at the poles. However, due to our constantly changing vantage point from the Earth as it orbits the Sun, the apparent rotation of the star at its equator is about 28 days. The centrifugal effect of this slow rotation is 18 million times weaker than the surface gravity at the Sun's equator. The tidal effect of the planets is even weaker, and does not significantly affect the shape of the Sun
Interesting convective clouds bringing rain to the city.
In this image you can see the spring weather in a single photo, from stormy weather at the bottom of the clouds, to sunny at the top of these photogenic cumulonimbus.
Much encouragement to all and my best wishes to everybody in these critical days of pandemic.
Best viewed large.

You'll never believe what just happened at Canadian Tire.
There I was, shopping for some sh*t tickets for the RV when a proper commotion erupted just in front of me.
Brawling on the floor amidst a pile of spilled $20 camp chairs were a pair of human beings fighting over the very last Hamilton Beach Convection Toaster.
''I was here first!'' yelled the blue-haired one on the left, ''No, I was here first!'' yelled the red-hatted one on the right, until a third voice chimed in.
''Can't we all just get along?'' said the employee while separating the two grapplers.
"I'm offended" complained a random onlooker.
''That's racist'' complained a gleeful spectator while pointing at a Black Friday promotional poster.
That's when the idea hit me. What if you could shop for your favorite things in a virtual store without the hassle of engaging with humans? And what if your favorite things happened to be highly insightful photography courses that teach you practical ways to make the best out of your photography?
And then I wondered, where could you find such a magical store? For the life of me, I couldn't figure out this puzzle until I remembered a line from an old movie ''If you build it, they will come''.
So that's exactly what I did.
I built it, and here it is. www.fototripper.com/store/category/online-photography-cou...
The Fototripper Black Friday Sale Ends on Sunday and I promise there won't be any fights in the aisles. You can enjoy 50% off any off my tutorials without having to fight through a scrummage over future landfill trinkets.
Thanks for reading

P.S. This never actually happened... well, not to me anyway, and probably not in a Canadian Tire store, but who is to say it didn't happen somewhere at some time?
One of the unexpected benefits of Saharan dust is that it makes sunsets and sunrises even more vibrant, as the sun’s rays are amplified through the atmosphere’s thick layer. It can even cause the sunlight to burst into an impressive array of purples, pinks, oranges, and yellows. The dust is lifted up by convection and travels thousands of kilometres in just a week, reaching as far as the western Caribbean.
The protracted early winter cold of late 2010 was attributable to two surges of intensely cold Arctic air across Nordwest Europe.
The first, in late November, was from the northeast and outstanding for the heavy convective snowfalls originating over the still-warm seas, with some associated convective streamers extending inland downwind of coastal inlets.
In contrast, during the second cold wave (from the north), a small cyclonic development resulted in a significant,indeed locally very heavy, snow event

Hello there. I don't mind this version of flickr, too much. That silly sidebar set-up is gone! It is enjoyable to browse images, again.
Anyway, this photograph shows a not-rare but infrequent pairing of convective clouds and the seafog. Oh, and obviously the Golden Gate Bridge with the south tower. I should have some more stuff to upload, but I mainly wanted to say hi.

Thunderstorms
What is a thunderstorm?
A thunderstorm is a rain shower during which you hear thunder. Since thunder comes from lightning, all thunderstorms have lightning.
Why do I sometimes hear meteorologists use the word “convection” when talking about thunderstorms?
Usually created by surface heating, convection is upward atmospheric motion that transports whatever is in the air along with it—especially any moisture available in the air. A thunderstorm is the result of convection.
What is a severe thunderstorm?
A thunderstorm is classified as “severe” when it contains one or more of the following: hail one inch or greater, winds gusting in excess of 50 knots (57.5 mph), or a tornado.
How many thunderstorms are there?
Worldwide, there are an estimated 16 million thunderstorms each year, and at any given moment, there are roughly 2,000 thunderstorms in progress. There are about 100,000 thunderstorms each year in the U.S. alone. About 10% of these reach severe levels.

Crepuscular rays
Crepuscular rays /kr?'p?skj?l?r/ (more commonly known as sunbeams, sun rays, or god rays), in atmospheric optics, are rays of sunlight that appear to radiate from the point in the sky where the sun is located. These rays, which stream through gaps in clouds (particularly stratocumulus) or between other objects, are columns of sunlit air separated by darker cloud-shadowed regions. Despite seeming to converge at a point, the rays are in fact near-parallel shafts of sunlight. Their apparent convergence is a perspective effect, similar, for example, to the way that parallel railway lines seem to converge at a point in the distance. The sun rays do converge to the sun, but the sun is much further away than the rays might make it look like.[2]
The name comes from their frequent occurrences during twilight hours (those around dawn and dusk), when the contrasts between light and dark are the most obvious. Crepuscular comes from the Latin word "crepusculum", meaning twilight.[3]

Aptly named for its chaos of canyons, the Maze is one of the most remote areas of the U.S. Celebrated by writers such as Ed Abbey as a symbol of wilderness, the complex of canyons, buttes, and standing rocks provides isolation far away from human settlements and extractive developments such as grazing and mining. It is one of 3 districts of Canyonlands National Park in Utah, receiving a fraction of the visitation relative to the Needles and Island in the Sky districts.
This view of the afternoon sun cutting across the south fork of Horse Canyon highlights the brown Organ Shale formations known as the Chocolate Drops, though they look more like Hershey bar pieces. Ed Abbey likened them to “tombstones, or altars, or chimney stacks, or stone tablets set on end.” They are capped by White Rim Sandstone which is more resistant to erosion than the softer layers underneath. To the south (right) columns of the same formations occur, known as the Standing Rocks (The Plug and Standing Rock seen here, just left of Lizard Rock). In the distance convective clouds associated with a cold front passing through are dropping snow on the Abajo Mountains and Elk Ridge.

Cloud streets are long rows of cumulus clouds that are oriented parallel to the direction of the wind. Their technical name, more specifically, is horizontal convective rolls.

Thunderstorms generally don't occur in my area north of latitude 63° after mid July, rarely in August, but unprecedented in September.
So we were startled to hear thunder in the evening, and rushed outdoors to see lovely convection and hear one more rumble of thunder.
The Weather Service office in Fairbanks could barely see, on their radar, (because of the curve of earth) the tops of fairly lofty convection in my area, surprising not only me, but them.
We decided to do a little storm chase yesterday, as the forecast looked good for some convection.
The cape was at its highest around Peterbough and Norwich, but the first wave of storms came 4 hours earlier than forecast, we still headed over that way and waited while watching the radar. Then we could see some small systems starting to kick off around mid-Wales over to the West, however they were heading North East. We caught up with this storm near Ashbourne as the storm went over the White Peak, making for some great photo opportunities.

In the early morning hours an active MCS (Mesoscale Convective System) over the English Channel moved to the southern NorthSea. Near the Dutch coast it collapsed, but as a last sigh it pushed this shelfcloud over the western part of Holland.
I was almost too late because the shelfcloud was detached from the precipitation core and running a 10-20 km ahead of it....
A gentle breeze over shallow water; Budd Lake, Yosemite. Refractions on lower left, reflections at upper right.
At sunset, dying convective showers were lit by the sun on a fairly clear horizon. Temperature fell from 99F to 80F between 6:30PM and 7:30PM.
Dry air near the surface is preventing instability showers from reaching the ground. With record high temperatures expected this afternoon, I wouldn't be surprised to see some convective development in the form of dry thunderstorms. Max temperature expected to reach the mid 70's F.

ENG : Another view, this time it's the whole structure just before she approaches the coast.
Yesterday's storm developed was reminiscent of a dry line initiation of convection. It was a photographer's dream for catching these weather singularities.
Thanks Explore (#57). Best position (#15).
This late season line of storms was unique in that it produced an EF2 tornado (cell at extreme right): (more details --> www.weather.gov/cys/Sept2019GoshenCountyTornado).

Looking south from Cheyenne, WY this convective looking snow shower reveals cloud movement. Since it take time for precipitation to reach the ground, the cloud mass was moving quickly to the left. Taken with Fujifilm X-T3 and Fujinon 16-55mm lens.
Cumulus congestus clouds are characteristic of unstable areas of the atmosphere which are undergoing convection. They are often characterized by sharp outlines and great vertical development. Because they are produced by strong updrafts, they are typically taller than they are wide, and cloud tops can reach 6 kilometres (20,000 ft), or higher in the tropics. Cumulus congestus clouds are formed by the development of cumulus mediocris generally, though they can also be formed from altocumulus castellanus or stratocumulus castellanus as well.
