Abstract: Based on Shenzhen's temperature observations from 1953 to 2005, the temperature time series were represented with average, maximum and minimum temperatures. By using the statistical method, linear analysis and Mann-Kendall method, the change in temperature for Shenzhen was studied, and by contrasting the frequency and intensity during different periods before and after 1987, the change characteristics of disastrous weather and climate events were discussed. The results show that under the climate warming and the rapid development of Shenzhen, except the frequency of heavy rain events the extreme precipitation has become more serious after the 1990s. The annual number of thunderstorm days has decreased, and the haze phenomenon aggravated increasingly. The high temperature days and continuous high temperature events have obviously increased, while the low temperature and the low temperature with rainy events decreased. The frequency of the tropical cyclone influencing Shenzhen has decreased, but its impact on heavy rainfall become more serious.

Key words: climate warming, frequency, change trend, disastrous weather and climate events
