A Study of the Relationship between Global Warming and Hurricane Activity Based on Time Series

Abstract

Hurricane is a tropical cyclone whose maximal wind speed exceeds 32.7 ms-1. There are two main parameters of hurricane intensity: intensity of wind speed, frequency of the wind speed. Based on the time series model, this paper takes the relationship into account between two parameters and the annual global average temperature. By using the global annual average temperature data collected from NOAA 2000 to 2016 inclusive, the change rule of temperature warming is found out by time series, and the function relationship between temperature and hurricane activity is obtained through regression analyses. The final result is close to the true value, which shows that the hurricane activity has something to do with the phenomenon of global warming.
