Case Studies on Convective Storms / Case Study 9, 13 June 1974: Mature Storm Study a Small, Isolated, "Steady State" Convective Storm

The complement of observations of the storm included vertically pointing Doppler radar, time-lapse photography, and aircraft circumnavigations. The storm appeared to maintain itself by travelling along a convergence zone somehow induced by the storm's own wake.

Virtually no outflow features were detected in the ground measurements within the mesonetwork, and therefore the storm maintenance mechanism did not involve surface outflow. While little precipitation managed to reach the ground, the storm extended to the tropopause. The storm probably systematically recycled precipitation particles into the updraft.
