Variability of Extreme High Temperature and Response to Regional Warming over Chongqing
Based on the daily maximum temperature data in 1961—2006 from 33 sta tions in Chongqing, spatial distribution feature and longterm change tendency of annul extreme high temperature frequency and intensity and annul extreme maxi mum temperature are analyzed. The result shows that in recent 46 years the trend of annual extreme high temperature frequency is decreasing in the western part of Chongqing and increasing in the eastern part，but the increase/decrease tre nd is not significant. In the recent 46 years the annual extreme high temperatur e intensity and annual extreme maximum temperature strengthen gradually. Increas ing tendency of annual extreme high temperature frequency in response to regiona l warming of Chongqing is most remarkable. Increasing tendency of annual extreme maximum temperature in respon se to regional warming of Chongqing is stronger than annual extreme high tempera ture intensity.
