| 摘 要： | 针对东北地区53站的降水距平百分率和温度距平这两个基本业务要素，运用李维京等在1999年提出来的动力统计相结合和典型相关回归这两种方案，对国家气候中心T63动力延伸集合预报的500hPa月平均高度距平进行释用，对释用结果采用PS评分和同号率进行预测效果评估．结果表明：这两种方法有较好的应用价值。

| Abstract: | The 500hpa monthly-average height anomaly Of T63 dynamical extended forecast products of national climate center is explanatorily applied by the two methods of dynamical and statistical approaches that devised by LiWeijing in 1999 and canonical correlation regression.The results of explanative application are evaluated that aim to percentage of precipitation anomaly and temperature anomaly of in 53 observation stations of northeast China by PS grade and same symbol ratio. The result indicates that the two methods have finer application value. |
