Yesterday I made a picture of my favorite type of clouds: the Cumulonimbus. They are so beautiful and destructive at the same time, thats why I like them so much. Cumulonimbus are looking like cauliflower, but they contain the powers of nature which humans (luckily) can't control. Those clouds are 10 km high or more, they contain 20 - 100 million tons of water and hail, they create thunderstorms and can reach 120 km/h or more. Dominium terrae? Oh no, not with Cumulonimbus!
