Abstract

We discussed here a possibility of determining characteristics of the wind field near the sea surface in the regions of a tropical cyclone based on the radiation- wind models available. The grounds for the discussion is data on three tropical cyclones in the Pacific ocean, acquired with the VHF-SSM/I radiometer from onboard the DMSP satellite. Before making analysis, we have processed the data collected and have given its interpretation from the standpoint of meteorology. The wind fields reconstructed are compared with independent data from storm warning services. It is shown that the use of the radiation-wind models and algorithms developed for standard meteorological conditions allow one to retrieve, with good accuracy, such important wind field characteristics, in the tropical cyclone region, as the dimensions of a pre-storm zone, wind field asymmetry, local maxima in the wind field, etc.
