Based on the Nanjing daily observation data from1951 to 2007 in Jiangsu Province , the change of extreme weather events and the possible link with the regional climate warming was analyzed . The results showed that in recent 60 years low temperature, gale, thunderstorm and bad fog events in Nanjing had the declining trend, but the ash haze event increased obviously. High temperatures, heavy rain, high winds, fog and haze had strong inter-annual variations, but did not have obvious cyclical characteristics. The low temperature, hot and thunderstorms events had certain inter-annual and inter-decadal periodic changes. There were high correlation between the annual average temperature and some extreme weather events such as high temperature, sultry, low temperature, strong wind and ash haze.
