摘要: 根据北太平洋网格点月平均海温资料的统计分析,揭示了海面水温场与黄河上游年径流量丰枯的联系,并探讨了海温异常变化对径流的影响.同时建立了回归方程,利用海温资料对黄河上游年径流量作长期预测试验,效果良好.Abstract: According to analyzing the data on the mean monthlysea surface temperatures(SST for short) at grid points in the Northern Pacific,the relationships between SST field and yearly high-flow or low-flow in the upper Yellow River were revealed.The in fluence of abnormal changes of SST on the runoff was discussed.Meanwhile,theregression equation was established andthe data of SST was used to make longterm forecasting test on the yearly runoff in the upper Yellow River.The good effect was achieved.
