中文摘要: 通过对近百年El Nino/ L a Nina事件与北京气候相关性研究发现,El Nino/ LaNina事件与北京夏季( 6～8月)降水、平均最高气温(7月)和冬季(1月)平均最低气温之间相互关系显著。El Nino事件与夏季降水、冬季平均最低气温呈负相关,与夏季平均最高气温呈正相关,造成降水减少,气温年较差增大,大陆性增强的气候特点。L a Nina事件与夏季降水、冬季平均最低气温呈正相关,与夏季平均最高气温呈负相关,使降水增加,气温年较差减小,大陆性减弱的气候特点。

Abstract:Results of the analysis suggest that during the recent 100 years there exists a strong correlation between the El Nino/La Nina phenomenon and Beijing′s rainfall in summer(June —August),mean monthly maximum temperature (July) and mean monthly minimum temperature in winter (January).El Nino phenomenon appears a negative-correlation with the summer rainfall and the mean monthly minimum temperature;whereas a positive correlation with the mean monthly maximum temperature in summer.La Nina phenomenon appears a positive correlation with the summer rainfall and the mean monthly minimum temperature in winter;whereas a negative-correlation with the mean monthly maximum temperature in summer.
