Question

Quizplus · Accepted Answer

A large temperature gradient between the lake surface temperature and the lower atmosphere is a key condition for the development of a lake effect storm. This occurs when cold, dry air passes over a comparatively warm lake, causing convective instability and creating localized areas of heavy snowfall. Moisture advection associated with an mP air mass (A) or a cPw air mass (B) may contribute to the development of the storm, but the temperature gradient is the most important factor. Strong southerly flow (D) would likely prevent the development of a lake effect storm, as it would bring warmer, more stable air over the lake.
