摘要
本文以天山以北地区主要河流春季流量的丰枯为背景,分析了北疆春季丰枯前期北大西洋海温特征及500hpa平均环流特征.从而提出大西洋海温影响北疆地区春季水量的一种可能机制,为新疆的长期水文预报提供一个可能的物理放据。
The paper reveals the effect of anomalous sea surface temperature (SST) districution over the North Atlantic Ocean on the trough and ridge in westerlies, as well as the connection between anomalous SST distribution and plenty or deficiency of discharge in spring in north Xinjiang region, At last, the paper puts forward a possible mechanism through which the SST of the North AtlanticOcean affects the discharge in spring in north Xinjiang, and provides a possible physical basis for long-range hydrologic forecast of the region,
