【摘要】 利用山西省1961-2006年夏季降水量资料和四种东亚夏季风指数,采用相关分析和距平分析法,对比分析了山西夏季降水与四种东亚季风指数的关联性。结果表明:山西夏季降水与四种东亚夏季风指数的相关性有好有坏,与郭其蕴GI和王斌WI指数的相关性均比与黄刚HI指数和李建平LI指数表现的好,但夏季降水与GI指数为正相关而与WI指数为负相关,其中高相关区分布在南部和中部;GI和WI指数距平符号对山西夏季降水异常有较好表征意义,尤其在干旱年份,而HI和LI指数几乎没有表征能力;GI和WI高指数年和低指数年降水差异明显,在南部和中部尤为显著,而HI和LI指数差异较小,且空间分布上有正有负。更多还原

【Abstract】 Based on the summer precipitation data of Shanxi province during 1961 to 2006 and the four East Asian summer monsoon indices,the relationship between different summer monsoon indices and the summer rainfall of Shanxi was analyzed with correlation and anomaly methods.The results showed that there was good correlation between four summer monsoon indices,but they had distinct effect on reflecting generally acknowledged strength of monsoon.GI index and WI index indicated better correlation between the summer rainfall of Shanxi than HI index and LI index.The high correlation of GI index and WI index distributed in the north and the middle parts of Shanxi,but GI index was positively correlated and WI index was a negative correlation.The representation of anomaly sign of GI index and WI index to precipitation anomalies of the summer rainfall in Shanxi was better than HI index and LI index,especially in the drought years.There were more significant differences between years of high index and low index of GI index and WI index than that of HI index and LI index,particularly in the north and central parts of Shanxi.更多还原
