摘要

采用中尺度数值模式WRF对2016年8号飓风马修进行了数值模拟。经过对实际情况的验证,WRF对这次飓风暴雨过程的模拟效果较好,可以基本反映飓风的演变过程。为了分析其内部结构,利用风云三号极轨平台上的微波温湿度测深仪(MWHTS)对低空卫星观测数据进行匹配,反演大气剖面。然后利用WRFDA模式主动式和被动式微波观测的最佳路径与预报路径对比,利用高时空分辨率的模拟结果对马修短时强暴雨进行诊断分析。

Atmospheric Retrievals in Hurricane Based on MWHTS Aboard FY-3C Satellite
The mesoscale numerical model WRF is used to simulate the No. 8 hurricane Matthew in 2016. With the verification to the real situation, the process of the hurricane rainstorm is well simulated by WRF in this case that it could basically show the hurricane evolution. In order to analyze the inner structure, the nadiral satellite-based observations were matched between the Microwave Humidity and Temperature Sounder (MWHTS) instrument aboard the FY-3C polar-orbiting platform to retrieve atmospheric profiles. Then use the simulation results with high spatial and temporal resolution to do diagnostic analysis on the short term heavy rainstorm caused by Matthew, with a comparison between best track and forecasting tracks using active and passive microwave observations from WRFDA model.
