Abstract:

Large-scale Organized Structures cloud streets and dendritic formations, LOSs are common in the Marine Boundary Layer MBL when wind shear and MBL stability are favorable. We found that the continuous wavelet transform was an effective way to characterize LOSs from in-situ data. Compared to unorganized convection, LOSs enhance exchange with the free troposphere and are more effective at distributing seasalt aerosol throughout the MBL. Since relatively particle-rich updrafts occur under cloud, satellite data are likely to underestimate optical effects of aerosols in the MBL.
