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/ L aNina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 。
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.
