    摘要:

    利用1951~2000年太阳10.7cm射电流量、全国160站观测到的降水和气温距平资料,分析了太阳活动异常对中国夏季、冬季降水和气温的影响。结果表明:太阳活动强的年份,夏季南方、东北少雨,黄河中上游流域、黄淮地区以及长江中上游则多雨;冬季全国均多雨。北方(尤其是东北和新疆)冬季气温偏高,夏季气温偏低。太阳活动弱的年份,夏季华南及黄河以北多雨,而长江流域及以北到黄河中上游夏季则少雨;冬季全国均少雨,北方冬季气温偏低。进一步讨论了中国东北地区夏季降水与太阳活动的密切关系。

    Abstract:

    The impacts of abnormal solar activities on precipitation and temperature in summer and winter in China are analyzed based on the 10.7 cm solar radio flux data and the precipitation and temperature data of 160 weather stations across China from 1951 to 2000.The results show:(1) In high solar activity years,there occurs more precipitation in summer in the upper and middle reaches of the Yellow River and the Changjiang River,as well as over the Huanghuai region,but there occurs less precipitation in summer in South China and Northeast China.At the same time,there is more precipitation in winter across China.There is higher temperature in winter in North China,especially in Northeast China and Xinjiang,and lower temperature in summer.(2) In low solar activity years,there is more precipitation in summer in South China and the regions north of the Yellow River,while there is less precipitation in summer over the Changjiang River basin and the upper and middle reaches of the Yellow River.In winter,there is less precipitation across China and lower temperature in North China.The close relation of summer precipitation in Northeast China and solar activities is further discussed.
