The Trend and Inter-decadal Evolution of Extreme Temperature Events in Beijing Area
The trend and inter-decadal evolution of extreme temperature events in Beijing area have been investigated by using daily mean temperature data from 20 meteorological stations in recent 30 years ( 1978 ～ 2007 ).The results indicate that the trend is almost similar between Beijing observatory and the average of all stations in Beijing region.The result of inter-decadal evolution shows that the frequency of maximum temperature in the urban areas increase obviously, which is inseparably close to urban heat island.Adversely, the spatial distribution of winter minimum temperature has no obvious relation with the mean temperature in winter.
