- Cloud types, Cb: a solitary, giant tower (see W005901Z) has exploded upward and is now flaring out as the rising updraft encounters the stable tropopause level. This Cumulonimbus cloud has a single gray stem above closer, lower clouds and is a briefly intense pulse storm. The anvil top spreads out uniformly in the light winds aloft. (1 of 3 in sequence)
