摘  要：
利用山西68个台站逐日最高气温、降水等资料,采用百分位值极端事件定义方法和Mann-Kendall突变检验、小波分析等方法,研究山西1961-2008年极端高温和极端强降水事件的变化特征。结果表明:1961年以来,山西极端高温日数呈显著增加趋势,趋势为5.9 d/10 a,20世纪90年代中期以前变化趋势不明显,1997年以来增多趋势显著。与此同时,极端强降水事件趋于减少。极端高温事件在2001年发生了突变,2001年以后极端高温事件显著增多。极端高温日数有3～4 a,8～12 a及30 a的周期,极端强降水日数有准3 a,6～10 a及准16 a的周期。极端高温事件的增加与气候变暖有密切联系,Nino_3区海温、欧亚地区的纬向环流及西太平洋副热带高压(下称西太副高)对极端高温事件有很大影响,当Nino_3区海温偏高、纬向环流偏强、副高面积偏大、位置偏西时,容易导致极端高温日数偏多。极端强降水的发生则与东亚季风和Nino_3区海温有密切联系,当季风强盛、Nino_3区海温偏低时,往往引起极端强降水事件增多。

摘  要：
In this paper,the events of extreme high-temperature and extreme heavy-precipitation in Shanxi Province were analyzed using Mann-Kendall test and wavelet analysis based on the daily highest temperature and precipitation data observed by 68 meteorological stations.The results show that the increase of extreme high-temperature was significant with an increase rate of 5.9 d/10 a,it was not so high before the mid-1990s but significant since 1997.Moreover,the extreme heavy-precipitation days were decreased in recent 48 years,but the trend was not obvious.There was a sharp change of extreme high-temperature days in 2001,and the extreme high-temperatures days were increased significantly since 2001.The increase of extreme high-temperature days was closely related to climate warming,and it was strongly affected by high sea temperature in Nino_3,strong latitudinal circulation over Eurasia and large-area Western Pacific High.The increase of extreme heavy-precipitation days was closely related to the low sea temperature in Nino_3 and strong East Asian Monsoon.
