SAR-Related Stress Variability in the Marine Atmospheric Boundary Layer (MABL) (High Resolution ARI)

Abstract

By stressing the sea surface, the marine atmospheric boundary layer (MABL) can alter the sea surface wave field and so can produce discernible signatures on SAR images of the ocean (e.g. Visecky and Stewart 1982). Among the resulting signatures, the quasi-linear and cellular microscale patterns still require adequate explanation. The ubiquitous MABL two- and three-dimensional convective circulations provide promising candidates for the forcing phenomena producing these signatures. These microscale circulations have horizontal wavelengths on the order of 1 to 10 times the boundary layer depth, or approximately 1 to 10 km, and temporal scales on the order of 1 to 10 hours. Thus, they produce stress variations on the spatial and temporal scales of the quasi-linear and cellular SAR signatures.
