英文摘要: This paper presents a rain rate retrieval algorithm for tropical cyclones (TCs) using passive microwave Fengyun-3B (FY-3B) MWRI brightness temperature (TB). Channel 18.7 and 36.5GHz of FY-3B/MWRI are used to implement retrieval algorithm. Two databases are constructed: one is 15,153 matchups of MWRI TB and NSIDC global swath ocean products for rain rate retrieving and another databset of 5,093 matchups retrieved rain rates and NSIDC rain rate products is used for error estimation of the retrievals. The retrieved rain rates show good agreement with the NSIDC surface rain rates in rain structures. Although there are slightly overestimated at heavy rain rates, the total bias is only 0.8467 mm/h and the total rms is 4.3475 mm/h even in the intensive TCs. This is submitted for the special session of "New Developments of Chinese Oceanographic and Meteorological Satellites".
