Analysis on the Characteristics of Typhoon Affecting Shenzhen City From 1961 to 2018

By using ArcGIS spatial analysis technology and information diffusion technology, the characteristics of typhoons affecting Shenzhen from 1961 to 2018 are analyzed in this paper. The results suggest that the frequency of typhoons entering the 300 km buffer zone of Shenzhen shows an obvious downward trend, and the probability analysis shows that Shenzhen is vulnerable to severe tropical storms and higher magnitude of typhoons. The annual precipitation caused by typhoon and its proportion to the total annual precipitation in Shenzhen show an obvious downward trend, while the extreme wind speed shows a weak downward trend. The analysis of three types of landfall typhoons shows that typhoons landing on the west side of Shenzhen often have a strong wind and rain impact on Shenzhen, typhoons landing on the east side of Shenzhen can have a more sustainable impact, and typhoons landing from south of Shenzhen generally have a relative weak impact on Shenzhen.
