Supercell thunderstorms occur when
the warm updraft punches through an overlying, stable layer and continues upward into a zone of cool, dry air.
Due to the heating of the surface in connection with sufficient humidity,
a warm updraft is released in the atmosphere.

In the simulation, this caused a plume of
warm, moist air to rise from the lake at a top speed of 194 kilometres per hour, similar to the
updraft speed in thunderstorms on Earth.
A low - altitude flow of
warm, moist air from an ocean area combined with a flow of cold, dry polar air high up creates maximum instability, which means that parcels of air heated near the surface rise rapidly, creating powerful
updrafts.
In the absence of horizontal differential heating to anchor convection cells, cells could tend to maintain themselves via the inflow to
updrafts and downdrafts being
warmed and coolded along the way so that the cells reinforce horizontal temperature variations that organize them.
Eventually you get a thunder storm which, develops a strong
updraft and pulls in
warm moist air to feed the storm.
Clouds are negative feedback driven nucleation points — when daytime clouds start to form the albedo causes further cooling beneath them and heat - engine thunderstorms form from the
updrafts of
warm wet air lofted up to the stratosphere to efficiently cool and spread, creating a local convective cell that pulls heat out of the ocean (or the moist land or air) and moves it to a cold reservoir.
Every now and then, however, the shear is low and a cluster of thunderstorms joins up and creates a persistent
updraft as
warm wet air is pulled into the low pressure underneath, is lifted up (cooling), and falls back as much cooler rain.
