CHANGE TRENDS OF EXTREME CLIMATE EVENTS IN CHINA

The variations of extreme climate events such as cold wave, typhoon, hot and cold days havebeen discussed using the recent 45-year data. The reductions of nationwide cold wave activities andannual 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 withcooling summers. The typhoon variation has connection with the tropical Pacific sea surfacetemperature conditions. The increments of drought/flood events since 1980s may be connectedindirectly with climate warming up significantly since 1980s. The climate variability of theseextreme climate events has decreased with time since 1980s.
