Abstract
Wuhan has experienced frequent floods in recent years as a result of global warming. In this paper, using the rainfall data of Wuhan meteorological station from 1960 to 2016, rainfall indicators such as annual rainfall, annual rainfall days and rainstorm days were selected to analyze the rainfall characteristics and change trends in Wuhan city in the past 60 years. The study shows that the annual rainfall in Wuhan shows a trend of significant increase, while the annual number of rainfall days is decreasing significantly. Rainfall is primarily concentrated from April to August, with June and July accounting for 25.9% and 27.4% of the year, respectively, in terms of rainstorm days. The annual rainstorm days, annual maximum 1-day rainfall, maximum 3-day rainfall, maximum 5-day rainfall, maximum 7-day rainfall and maximum 15-day rainfall all show an increasing trend, indicating an increased risk of extreme rainfall in Wuhan.
