CHANGE TRENDS OF EXTREME CLIMATE EVENTS IN CHINA

The variations of extreme climate events such as cold wave, typhoon, hot and cold days have been discussed using the recent 45-year data. The reductions of nationwide cold wave activities and annual cold day number in northern China all have close relationship with warming winters, especially during 1980s and early 1990s. Decrements of annual hot day number are associated with cooling summers. The typhoon variation has connection with the tropical Pacific sea surface temperature conditions. The increments of drought/flood events since 1980s may be connected indirectly with climate warming up significantly since 1980s. The climate variability of these extreme climate events has decreased with time since 1980s.
