Mesoscale convective rolls and cells are frequently formed in the unstably stratified atmosphere over the
ocean as follows from analysis of satellite visible, infrared, passive microwave and radar images. To interpret
sensing data taken in different spectral ranges, models describing fields of oceanic and atmospheric parameters
in convective open and closed cells and rolls were suggested. Models include synoptic-scale, mesoscale and
random components. Models were used for calculation of fields of the brightness temperatures ТB(ν) and radar
backscattering σº at frequencies ν of Aqua AMSR-E and Envisat ASAR with taking into account instrument
noises. Тя(ν) and σº fields computed at variations of hydrometeorological parameters and sensing geometry are
in good agreement with satellite measurements.
