Presentation transcript:

Importance of Low-Clouds for Climate Imperative that we understand the processes controlling the formation, maintenance and dissipation of low clouds in order to improve their representation in climate models.

Can drizzle affect MBL dynamics?

Precipitation and its effects on albedo Cloud albedo strongly dependent upon open/closed cells Strong precipitation associated with open cell structure Open cells form in clear marine environment – potential anthropogenic impacts Open Cells Closed Cells Satellite Low albedo 100 km High albedo Strong drizzle Ship Radar Weak drizzle
