Dynamic Cooling: Occurs when strengthening storms produce strong upward motion and heavy precipitation that cools the atmosphere. The cooling happens because of two things. First, rising air cools as it becomes surrounded by a cooler environment and is further removed from the source of heat (sun-warmed surface objects). Second, heavy frozen precipitation falling into a warm layer will result in latent heat being transferred from the air to the melting hydrometeors so that a phase change (solid to liquid) can occur. The net loss of heat energy in the air will cause it to cool.
