Climate trends in tropical cyclone-induced precipitation and wind over Shanghai

The trends in annual precipitation and wind induced by tropical cyclones (TCs) over Shanghai during the last 40 years are estimated. Results indicate that there is a significant increasing trend in the annual total precipitation induced by TCs, which is related to the significant positive trends in daily precipitation and annual torrential rain days. Meanwhile, a significant decreasing trend shows in maximum sustained wind, which seems to be related to the downward trend in the intensity of TCs when affecting Shanghai. The annual frequencies of affected TCs, TC translation speed and distance from Shanghai when affecting Shanghai have no obvious tendency. The different trends in precipitation and wind suggested that a more comprehensive metric for assessing TCs' influence on society is necessary.
