Detection of convective instability in atmospheric boundary layer over the ocean by airborne Ku-band real aperture radar

The paper examines structural features of radar images obtained under unstable stratification of the ocean-atmosphere boundary layer. Manifestations of the dry and moist convective cells are of special interest. Near surface convective processes in radar images are investigated at different sounding directions relative to the mean surface wind. Images recorded by airborne side looking real aperture radar at a wavelength of 2.25 cm are considered. Radar images under discussion were recorded during joint Russia/US experiment JUSREX conducted in July 1992 in an area off the US coast, roughly 80 km south east of Long Island, New York.
