The storm activities in the West Pacific from 1980 to 2018

The storm is an important weather system that significantly affects socioeconomics and human living. This study uses the global tropical cyclone best track data from IBTrACS, along with other meteorological states from ECMWF ERA-5 reanalysis from 1980 to 2018. In the West Pacific, storms are more likely to occur in summer (July, August and September). During the 39-year period, the occurrence of storm activities tends to be less frequent in summer, accompanied by increased sea surface temperature, total precipitation and total column water. It is also found that the storm number exhibited a high correlation with sea surface temperature, surface pressure, total precipitation and total column water in the middle West Pacific as well as the sea of Okhotsk in summer.
