- Lake-effect clouds over the Great Lakes in autumn
- W869323S
- Lake-effect. When cool, unstable air passes over a large extent of warmer water (here, The Great Lakes in autumn), the air is heated by the water and rises to form convective showers. These clouds typically form over water and dissipate inland. The showers or weak storms have low tops and are often arranged in lines with the low-level winds.
