Mini Cloud Atlas
A multicell thunderstorm complex in southeastern Oklahoma. Several distinct cells were visible, contributing to the collective cloud mass. The fibrous anvil represented a stable layer along which cloud material spread after rising to an equilibrium level near the tropopause (troposphere-stratosphere boundary). Some convective cells in a multicell cluster release unusually large amounts of energy as they rise at great speed, punching well above the anvil layer before losing their buoyancy and falling back down. One such cell made the pronounced overshooting top on the west (right) side of the complex.
