长期气候预报方面的最新进展,使得对哥伦比亚河流域作出的有效流量预报约比目前依赖积雪场测量所作出的预报约提前6个月。预报时间提前有利于大大改进系统的运行性能,尤其在期望高于平均流量的年份。根据追溯到1931～1987年水文年的长期流量预报,采用不同的水库调度曲线进行的水库模型模拟表明,根据气候预报所推荐的替代运行方法,可增加哥伦比亚河上水电站的发电量5500GW·h/a,平均增加年收入1.53亿美元。
Recent advances in long-term climate forecasting have resulted in an estimated 6-month advance in effective flow forecasting over the Columbia River Basin over forecasts currently relied on snow-field measurements. Predicting time ahead helps to greatly improve the operational performance of the system, especially in years when it is expected to exceed the average flow rate. Based on the long-term flow forecast dating back to the hydrological year 1931-1987, reservoir modeling using different reservoir scheduling curves shows that the alternative operation proposed by climate forecasting can increase the power generation of the 5500GW · h / a , With an average annual increase of 153 million U.S. dollars.
