Abstract:
Based on 1951—2016 the best Tropical Cyclone (TC) track dataset of CMA-STI, Nino3.4 Index from the American Climate Prediction Center (CPC) and HadISST1 sea surface temperature (
SST) data from British Hadley Center, statistical analysis on the characteristics of intensity variation of different grade TC influenced China and their relations with ENSO were carried out. The results show that the intensity of above-grade TCs influenced China has being intensified, and the intensity of strong typhoons and super typhoons increase significantly in recent years. TCs influenced China were in the second strongest period only after 1950s-1960s during the study period. In August of El Nino years and October in La Nina years, the increasing intensity characteristic index of TC is the largest in the corresponding period of normal years, the reasons caused the events may be the anomalous changes of
SST and other air-sea variables in the ENSO years.
