Thunderstorm initiation mechanism
From Glossary of Meteorology
thunderstorm initiation mechanism
Rising motion associated with an atmospheric feature capable of releasing convective instability leading to thunderstorm development.
Examples are rising motion associated with fronts, the dryline, gust fronts, upper-air disturbances, heated elevated terrain, terrain–airflow interaction, and sea breezes and other mesocale circulations resulting from horizontal gradients in radiative properties of the underlying surface.
