Summary Authors: Lubor; Jim Foster
The panorama above shows a huge cumulonimbus anvil (Cumulonimbus incus) near Pilsen in the Czech Republic. The camera is looking east as the Sun is setting. These impressive clouds are the product of mature thunderstorms and take on a classic flat-topped anvil shape when spreading along the tropopause. In the upper reaches of the troposphere, storm updrafts eventually encounter stable air layers and are no longer able to expand vertically. Photo taken on June 7, 2009.
