摘要：

The accurate information on intensity and location of tropical cyclones (TCs) is essential for weather forecasting and warning. With atmosphere thermal profiles retrieved from microwave sounding instruments, the intensity and location of two major hurricanes are estimated based on the atmospheric hydro-static balance equation. Results show that the use of ATMS products derived from the scene-dependent one-dimensional variation (SD1DVAR) could reduce the errors in estimating the location and intensity of tropical cyclones by 52.79% and 36.91%, respectively, compared with the use of NOAA's operational products. Also, using a combined sounding data from FY-3D MWTS with MWHS that has 118 GHz channels could reduce the intensity estimation error by 37.2%. Moreover, SD1DVAR performs very well for both ATMS and MWTS/MWHS. More instruments will be tested to generate a global TC dataset with high temporal resolution.
