Based on the track data of tropical cyclones in the Arabian Sea from 1982 to 2020 provided by the India Meteorological Department (IMD) and the International Best Track Archive for Climate Stewardship (IBTrACS), and the reanalysis data provided by the National Centers for Environmental Prediction (NCEP) , the source and track characteristics, active area, seasonal and interannual variation characteristics of frequency and accumulated cyclone energy (ACE) index of tropical cyclones in the Arabian Sea in recent 39 years are analyzed, and the physical causes are explained in combination with environmental factors. The results show that tropical cyclones in the Arabian Sea mostly occur in the sea area of 10°~25°N, 65°~75°E. The frequency and intensity of tropical cyclones are high from May to June and September to December. In contrast, from January to April and July to August, the frequency of tropical cyclones is low, and the maximum wind speed near the center of cyclones is less than 35 kn. It is found that the seasonal variation of frequency of tropical cyclones is mainly controlled by vertical wind shear, while interannual variation is mainly controlled by sea surface temperature (SST) and 850 hPa relative humidity. The occurrence frequency and ACE of tropical cyclones in the Arabian Sea are increasing in recent years.
