中文摘要：

这研究在 6 月和 7 月使用车站在 5 月和东方亚洲夏天季风(EASM )降水调查在土壤温度之间的关系在从 1971 ～ 2000 的西北中国上的观察土壤温度数据。在 80 厘米的深度的土壤温度的记忆能在 5 月坚持至少 2 个月，和土壤温度，这被发现仔细在 6 月和 7 月被连接到 EASM 降水。当土壤温度在在西北中国上的 5 月是更温暖的时，更少的降雨在 Yangtze 和 Huaihe 河山谷上发生，但是更多的降雨在 6 月和 7 月发生在华南上。在在西北中国上的 5 月的积极异常土壤温度在东亚的大陆的大多数部分上对应于更高的 geopotential 高度，这被建议，它趋于削弱随后的 EASM。而且在 6 月和 7 月，一个气旋的发行量异例发生在东南中国和西北上，太平洋和一个逆旋风的异例在 850 hPa 出现在 Yangtze 和 Huaihe 河山谷。所有上面趋于在 Yangtze 和 Huaihe 河山谷压制降水。结果也显示在在西北中国上的 5 月的土壤温度是仔细与东方有关亚太(EAP ) teleconnection 模式，和它可以为东方亚洲夏天季风降雨作为一个有用预言者被采用。

英文摘要：

This study investigates the relationship between the soil temperature in May and the East Asian summer monsoon （EASM） precipitation in June and July using station observed soil temperature data over Northwest China from 1971 to 2000.It is found that the memory of the soil temperature at 80-cm depth can persist for at least 2 months,and the soil temperature in May is closely linked to the EASM precipitation in June and July.When the soil temperature is warmer in May over Northwest China,less rainfall occurs over the Yangtze and Huaihe River valley but more rainfall occurs over South China in June and July.It is proposed that positive anomalous soil temperature in May over Northwest China corresponds to higher geopotential heights over the most parts of the mainland of East Asia,which tend to weaken the ensuing EASM.Moreover,in June and July,a cyclonic circulation anomaly occurs over Southeast China and Northwest Pacific and an anticyclonic anomaly appears in the Yangtze and Huaihe River valley at 850 hPa.All the above tend to suppress the precipitation in the Yangtze and Huaihe River valley.The results also indicate that the soil temperature in May over Northwest China is closely related to the East Asia/Pacific （EAP） teleconnection pattern,and it may be employed as a useful predictor for the East Asian summer monsoon rainfall.
