一、遥 联 实 况 前期南方涛动指数(SOI)对汎期西太平洋副高的强弱,脊线的纬度及脊点的经度均有显著作用,因此,它对每年夏季江淮流域的旱涝分布也可能存在相当的影响.为此,分别计算了上年1月至当年7月各月SOI(其值的确定见参考文献[1])与夏季江淮流域12组雨量的相关值.它们分别是:长江中下游(29°—32°N,113°E以东)10站,苏南区 First, the teleconference state of the former South Oscillation Index (SOI) has a significant effect on the subtropical high in the western Pacific during the flooding period, the latitude of the ridgeline and the longitude of the ridge point. Therefore, There may be considerable effects.Therefore, the correlations between the monthly SOI (the determination of the value of which is found in reference [1]) and the 12 sets of rainfalls in summer and the Yangtze River and Huaihe River Basin are calculated separately from January to July of the previous year, respectively : 10 stations in the middle and lower reaches of the Yangtze River (29 ° -32 ° N, east of 113 ° E), Sunan area
