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 $$150^\circ {\text{E}}$$ 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% of the total impact of the Northwest Pacific TCs; some provinces in the north are mainly affected by the TCs generated in the region; there is a flat X path in the Northwest Pacific Ocean, and the high impact TC mainly affects China through this path; from July to September, near the flat path, it is more likely to observe high impact TC.
