Sunset Clouds
< PreviousNext > 
Here are some towering cumulonimbus clouds passing by our house. Often these clouds tend to travel in a line with the biggest, most mature, clouds upwind, while the smaller downwind clouds suck the power out of the bigger ones. The frizzy edges to the left of this main updraft means that it was not very powerful and was already dieing. It probably produced some rain, but nothing more. You can see the build up of clouds to the left of it which was a new updraft in the making. If many of these smaller updrafts (called cells) combine you get a supercell, and these can lead to severe storms and tornados and such.
