Popis: An approach to studying the processes of hurricane onset in the Gulf of Mexico is considered by analyzing the cooperative (averaged over the basin of the Gulf) response of the total atmospheric moisture content to these processes based on the data of satellite microwave radiometric measurements. The spatiotemporal variability of moisture content in different years during the periods of the onset and development of local tropical hurricanes Humberto (2007), Lorenzo (2007), Bret (1999), and Katia (2017) has been analyzed based on the data from DMSP satellites (SSM/I and SSMIS radiometers) and EOS Aqua (AMSR-E radiometer). A cooperative response of the moisture content in the atmosphere to the development of these hurricanes over vast areas of the Gulf of Mexico located at a considerable distance (up to 500–700 km) from the regions of their origin has been observed. A common feature for hurricanes Humberto, Lorenzo, Bret, and Katia was revealed: an increase in the spatial variability of the total moisture content of the atmosphere over the Gulf of Mexico over several days and its further weakening (calm) before the final stage—the appearance of the hurricane. The tasks of further research are discussed.
