Abstract
The results of the analysis of images of surface heat flows in the areas of origin of a number of hurricanes in the Gulf of Mexico and the tropical Atlantic, obtained with the satellite microwave and IR radiometric measurements, are presented. An increase in the intensity of latent and sensible heat fluxes during 4–5 days in the periods preceding the origin of hurricanes and their localization in certain areas, is discovered.
