| 摘 要： | 利用重庆1961-2006年31个站逐日最高温度资料,统计出年极端高温发生频次、年极端高温强度、年极端最高温度,分析了它们近46年来的变化情况.结果表明:近46年来重庆年极端高温发生频次呈西减东增的趋势,但增加/减少趋势并不显著.年极端高温的强度和年极端最高气温均在不断增强.年极端高温发生频次的增加对于重庆区域增暖的响应最显著,而年极端最高温度的升高比年极端高温频次的增加对重庆区域性增暖的响应偏弱,但又比年极端高温强度的增强对重庆区域性增暖的响应程度要偏强.

| Abstract: | Based on the daily maximum temperature data in 1961-2006 from 33 stations in Chongqing, spatial distribution feature and long-term change tendency of annul extreme high temperature frequency and intensity and annul extreme maximum 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 trend is not significant. In the recent 46 years the annual extreme high temperature intensity and annual extreme maximum temperature strengthen gradually. Increasing tendency of annual extreme high temperature frequency in response to regional warming of Chongqing is most remarkable. Increasing tendency of annual extreme maximum temperature in response to regional warming of Chongqing is stronger than annual extreme high temperature intensity. |
