A series of mature thunderstorms, located near the Parana River in southern Brazil, can be seen in this low oblique view. With abundant warm temperatures and moisture-laden air in this part of Brazil, large thunderstorms are commonplace. A number of overshooting tops and anvil clouds are visible at the tops of clouds. Storms of this magnitude can drop large amounts of rainfall in a short period of time causing flash floods. Some of these tropical thunderstorms can penetrate into the stratosphere to altitudes of more than 12.5 miles (20 km).
