During sunset, a cloud flew in in an amazing shape (a bird, a dragon, and maybe an angel ...)
A little understanding of the physics of cloud formation underscores the complexity of the atmosphere and sheds light on why predicting weather for more than a few days is such a challenge.
Six types of clouds you can see and how they can help you understand the weather.
1) Cumulus clouds - On a sunny day, rays warm the earth, which heats the air located directly above it. The heated air rises upward due to convection and forms cumulus clouds. These “good weather” clouds are like cotton wool. If you look at the sky filled with cumulus clouds, you can see that they have a flat bottom, located at the same level for all clouds. At this altitude, air rising from ground level cools down to the dew point. It usually doesn't rain from cumulus clouds, which means the weather will be good.
2) Cumulonimbus clouds.
Small cumulus clouds do not rain, but if they grow and grow in height, it is a sign that heavy rain is coming soon. This often happens in summer when morning cumulus clouds turn into cumulonimbus during the day. Cumulonimbus clouds often have a flat top. Air convection occurs inside such a cloud, and it gradually cools until it reaches the temperature of the surrounding atmosphere. At this moment, it loses its buoyancy and can no longer rise higher. Instead, it spreads out to the sides, forming the characteristic anvil shape.
3) Cirrus clouds form in very high layers of the atmosphere. They are smoky because they are composed entirely of ice crystals falling in the atmosphere. When cirrus clouds are carried by winds moving at different speeds, they take on a characteristic curved shape. And only at very high altitudes or at high latitudes, cirrus clouds give out rain that reaches the ground.
4) Stratus Clouds - A low-lying, continuous cloud sheet that covers the sky. Stratus clouds are formed by slowly rising air or gentle winds that cover the cold land or sea surface with moist air. Stratus clouds are thin, therefore, despite the gloomy picture, it is unlikely to rain from them, a little drizzle at most. Stratus clouds are identical to fog, so if you've ever walked in a mountainous area on a foggy day, you've been inside a cloud.
5) Lenticular clouds. Smooth and lenticular lenticular clouds form when air is blown up and over a mountain range, and as it travels over a mountain, the air descends to its previous level. At this time, it heats up and the cloud evaporates. But it can slip further, as a result of which the air rises again and forms another lenticular cloud. This can result in a chain of clouds extending far beyond the mountain range. The interaction of wind with mountains and other surface features is one of the many details that must be taken into account in computer simulations to obtain accurate weather predictions.
6) Kelvin - Helmholtz like a breaking ocean wave. When air masses at different heights move horizontally at different speeds, their state becomes unstable. The boundary between the air masses begins to ripple and form large waves, such clouds are quite rare.

Grey Crowned Crane, Balearica regulorum, in the Houston Zoo.
Widespread in Africa, but classed as endangered since 2012 due to habitat loss. Have you noticed that human fondness for charismatic megafauna has not—in all these years since the original Earth Day—translated into habitat preservation?

Happy Bird Thursday!
Tomorrow I'm going to show you a surrealist film stock that produces truly fascinating colour effects. In the meantime this is what can be done with digital processing.

“We will live in this world, which for us has all the disquieting strangeness of the desert and of the simulacrum, with all the veracity of living phantoms, of wandering and simulating animals that capital, that the death of capital has made of us—because the desert of cities is equal to the desert of sand—the jungle of signs is equal to that of the forests—the vertigo of simulacra is equal to that of nature—only the vertiginous seduction of a dying system remains, in which work buries work, in which value buries value—leaving a virgin, sacred space without pathways, continuous as Bataille wished it, where only the wind lifts the sand, where only the wind watches over the sand.”
Jean Baudrillard (French philosopher)
The simulacrum is never what hides the truth-- it is truth that hides the fact that there is none. The simulacrum is true

With gusts over 45mph it's a hang on to your hat kind of day. I was lucky to get this shot in before the wind really began to crank it up.

I can't help it but every once and a while at sunset I have to go up to the top of Mount Tolmie and flood Victoria.
Enjoy the holiday weekend everyone!
On a personal note I started today with 2,999,567 aggregate views. I should pass 3M in a few hours. Thanks to everyone.
Update: to celebrate my 3M views this photo is #3 in Interestingness at the moment. Thanks everyone!

A Kodachrome reedit (1960s Kodachrome)
Part of my occasional dive back into my photos looking for dig photos that I think would be good as a Kodachrome simulation preset since the Kodachrome of my past is long gone. I miss Kodachrome and I am hardly alone, but Kodachrome was so complex to process it is unlikely anyone will ever bring it back.
CAMP PENDLETON, Calif. – Marines with the Ground Combat Element, Black Sea Rotational Force 11, spent a few days in the Horno Canyon for urban warfare training using simulation paint rounds as a part of a Special Purpose Marine Air-Ground Task Force deploying to the Black Sea, Caucasus and Balkan regions. BSRF-11 has a unique mission to help promote regional stability, build partnerships with host nations and advise military training capacity of European armed forces training with U.S. troops. The GCE consist of Marines from various companies within the Anti-Terrorism Battalion, Bessemer, Ala. March.14, 2011
