Abstract:

Microwave sounders operating in the 53-55 Ghz frequency range are transparent to cloud cover and allow the mapping of the Tropical Cyclone TC warm core in the 350-100 hPa layer. A robust relationship exists between the brightness temperature Tb anomalies measured by satellites in this layer and aircraft-measured Minimum Sea Level Pressure MSLP anomalies. Since 1998 the Advanced Microwave Sounding Unit AMSU flown aboard the Polar Orbiting Environmental Satellite POES series of spacecraft has been used to exploit this relationship. Algorithms developed separately at CIMSS and CIRA make use of the AMSU temperature and moisture sounder channels to produce estimates of MSLP and Maximum Sustained Wind MSW. This poster will present results of a new algorithm to estimate TC intensity using the microwave sounder aboard the Special Sensor Microwave ImagerSounder SSMIS flown aboard the DMSP series of satellites.
