A055:
Land Surface and Boundary Layer Influences on Moist Convection





Session ID#: 22834

Session Description:
Land surface characteristics and processes in the boundary layer can exert great influence on moist convective dynamics. For example, the contrasts in the properties of contiguous land surfaces can give rise to thermally direct mesoscale circulations, also known as ‘land breezes’, which, in turn, can facilitate the initiation of deep convection. Cold pools generated by evaporatively cooled downdrafts, over land or over the ocean, are also acknowledged to be essential components of the transition from shallow to deep convection. This session aims to explore new advances in this important area of research, many aspects of which still remain to be fully understood. Contributions are welcome that investigate land surface heterogeneities, sea/land breezes, cold pools, and how these affect the initiation and evolution of moist convection.
