北京天津等地气温降水量历史资料诊断

Diagnostic Analysis of Historic Temperature and Precipitation in Beijing and Tian jin

  • 摘要: 采用北京、天津、沈阳、哈尔滨等6站近百年的实测资料,诊断分析了华北、东北地区的气温和降水量的变化趋势及相互关系。分析结果表明:近百年来北京等地年平均气温和冬季1月的月平均气温均有上升趋势,且东北地区比华北地区上升的幅度大,冬季1月的月平均气温比年平均气温上升幅度大。部分地区的夏季7月的月平均气温呈下降趋势。同期月平均气温和月降水量有负相关关系,尤其以5月、6月、7月最为明显。

     

    Abstract: In this paper the trends of temperature and precipitation in North China and Northeast China and their relationshop are analysed using observed data in the past 100 years in Beijing,Tianjin,Shenyang and Haerbin stations. The result indicats that in the past 100 years annual mean temperature and monthly mean temperature in January in winter have a increase trend. And the magnitade of increase is greater in Northeast China than that of in creast in North China,the magnitade of the monthly mean temperature in Jan in winter is greater than that of the annual mean temperature. The monthly mean temperature in July in summer is a decrease trend in some regions. There is a inverse correlation between monthly mean temperature and precipitation,especially for May,June,July.
