This is a zone of rapidly rising motion at mid levels and a change of state of water vapor and associated energy releases as water vapor becomes liquid and solid with the flow then allowed to flare out into a large cirrus shield or thunderstorm anvils in the strongly divergent flow at the top of the troposphere.
