Analysis of tropical cyclone data over China's coastal waters and the Northwest Pacific Ocean for marine fisheries

Abstract

Tropical cyclones (TCs) have a serious impact on marine fisheries. More than 80% of marine disasters are caused by TCs. Based on the data of the best track of TCs in the Northwest Pacific Ocean, this paper analyzes the spatial distribution of TC influence duration. The analysis shows that: (1) in the Northwest Pacific, tropical depressions have the most extensive influence; the influence range of tropical storms is similar to that of severe tropical storms; typhoons gradually decrease around the southeast side of Taiwan island; From severe typhoon level, the influence of TCs is moving away from the mainland; super typhoons have obvious influence only in the east of Malaysia archipelago. (2) In terms of marine fisheries, severe tropical storm and typhoon level of wind resistant marine fishery facilities should try to avoid the waters on both sides of the line between Taiwan island and Malaysia islands; severe typhoon and super typhoon level of wind resistant marine fishery facilities are only at risk in the east of Taiwan island and Malaysia islands, and are basically safe in other waters.
