Characteristics of tropical cyclones formed in the Eastern Pacific Northwest

Typhoon is one of the main natural disasters affecting China. Every year typhoons cause lots of property losses and casualties. If the early warning department can issue early warning more time, it may reduce more losses. In this paper, we use TC path data, TC potential impact index method and density clustering algorithm, to study the characteristics of TC generated on the sea area east of 150^∘E in the Northwest Pacific Ocean (Eastern Northwest Pacific Ocean, ENPO). The results show that although the ENPO is far from China, the proportion of impact TCs is not high, but the impact on Zhejiang, Fujian, Jiangxi, Taiwan Province and other provinces accounts for 10–30
