Clouds are formed when warm air rises and water vapor condenses into clusters of water droplets. This condensation occurs at a specific temperature, so when conditions are stable, clouds are formed at a specific height, creating a flat layer. Near a thunderstorm, however, turbulent air causes pockets of water and ice to develop, resulting in these bumpy mammatus clouds (think “mammary clouds”).

This swirl also formed fast and the colors were brighter than the picture shows. Being a Bay Area, CA native, I’d never experienced such weather and when people started throwing out words like “tornado”, I got a little nervous. Again, taken in June of 2009 outside Denver, CO.

This photo illustrates a current situation in Prague, Czech Republic. What you see there is smog, which we haven’t seen here in quite a few years, so it took us completely by surprise. When I was taking this photo, the sun shone like crazy through the fog, but it turned out that it was just a wish made by mind completely unaccustomed to such a situation. While we all know that this is a kind of a big problem, I can’t help myself but to find this strange beautiful.

for escute — you can get an idea of how small the flakes are from the knitted wool, and you can see that yes, the patterns are sometimes visible.
A week after a 200-mile-an-hour (322-kilometer-an-hour) tornado destroyed much of Joplin, Missouri, a NASA satellite captured this false-color depiction of the destruction. In this image, vegetation is red, buildings are blue, and the tornado’s path is shown as a blue trail stretching from left to right.
