Towering Cumulus on the Dryline

Towering Cumulus on the Dryline

This is a much different breed of towering cumulus than the maritime version in the previous image. Here, unlike on a land breeze circulation, the low-middle level flow was strongly sheared, causing the tilt. The cloud looks less robust than the previous example because it was drawing in dry air from west of the dryline, on which it formed. This dry entrainment ultimately killed the whole cloud by evaporation. There is a nice arrangement of crepuscular rays around it, too.
