| 摘 要： | 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

| Abstract: | Accordi ng to the theory of gradient wind, the asymmetrical wind field of typhoon was achi eved. The large domain wind field and the initial wind field of the mesoscale dy namic diagnostic Mass model was obtained through nesting the typhoon wind model with that of the NCAR objective analysis. Then, using the Mass model we dynamica lly adjusted the wind field of some local key domain. At the same time, through Nudging assimilation scheme combined with real data to rectify the diagnostic wi nd field, we obtain the practical final wind field in coast and estuary regions. The diagnostic test against the 9015 and 9711 typhoon cases using the model sys tem in this paper produced reasonable results. |
