由梯度风平衡原理得出具有非对称性的台风模型风场 ,将台风模型风场与 NCAR客观分析风场嵌套得到大区风场并从中取出中尺度动力诊断模式 Mass所需的初始风场 ,再由 Mass模式对局部关键性区域海面风场作动力调整 ,同时结合实测资料使用 Nudging同化方法进行调整 ,从而获得具有较好实用性的台风近岸及河口区的海面风场。文中用上述模型对 90 15号和 9711号台风作了诊断分析试验 ,得到了比较合理的并符合实际观测的台风海面风场 The wind field of typhoon model with asymmetry is obtained by the principle of gradient wind balance. The typhoon model wind field is nested with NCAR objective analysis wind field to get the wind field of large area, and the initial wind field required for mesoscale dynamic diagnosis mode Mass , And then the Mass model is used to adjust the sea surface wind field in the key regional area. At the same time, the Nudging assimilation method is used in combination with the measured data to obtain the sea surface wind field with good practical typhoon nearshore and estuarine areas. The above model was used to diagnose and analyze Typhoon 9015 and Typhoon 9711, and a reasonable typhoon sea surface wind field
