- Clouds behind a mesoscale wind shift line in the clean blue sky
- W012337S
- Clouds behind a mesoscale wind shift line. The tail end of a gust front has swept past. Ahead of it is a completely clear sky while behind it in the cooler air, a few Cumulus clouds are left. The subsidence and downward mixing of drier air from above has evaporated most of the clouds which formed in the lift along the advancing outflow boundary.
