Abstract:Typhoon is a disastrous weather system which has a great change of path and intensity with ephemeral and strong collapsing force. Satellite remote sensing, especially satellite microwave imaging sensors, not only have the advantages of large scaled, dynamic, synchronous, fast observation etc., but also can work 24 hours all-weather, which can be used for monitoring and early warning of typhoon path and thus is considered as an efficient tool to analyze typhoon. Based on the data of three independent sensors including microwave satellite Advanced Microwave Scanning Radiometer(AMSR), TOPEX&Jason-1 altimeter and WindSat radiometer, the influence of typhoon on ocean is analyzed. The satellite measurement of ocean parameters relevant to typhoon is described, and finally the comparison of wind field ocean remote sensing results with currently used radiometers and scatterometers is shown. The conclusions are given as following: compared with infra radiometer, microwave radiometers have an observable advantage; and full polarization radiometers have the potential of measuring ocean wind field in bad weather conditions.
