摘 要: | 本文利用黑河流量资料,分析了径流本身的持续性、周期性及年际变化。统计表明,4月径流与前期2月青藏高原地面加热场强度存在较好的正相关。前期500 hPa高度距平特征可预示未来5月黑河流量。

Abstract: | Using the data set of the flow of Heihe river, we have analyzed the persistence, periodicity and annual variation of the flow. It is shown that there is a good positive correlation between the flow of Heihe river in April and surface heating field over the Qinghai-Xizang Plateau in February of the year. The departure characteristics of 500 hPa in March have the predictability to the flow of Heihe river for coming May. |
