| 摘 要： | 对MM5的人造台风风场方案进行了分析,并引入台风移速、移向、摩擦等客观因素构造非对称切向风场,尝试选择合理的径向风方案,并考虑风场垂直结构,改进出三维非对称台风风场模型.通过对"云娜"台风模式初始场的对比发现,径向风及高空反气旋环流的引入突出了台风的基本特征,与观测事实相接近.最后进行敏感性数值模拟,通过比较台风路径及移速、海平面气压、最大风速等模拟要素,结果表明:改进后的台风模型通过订正初始场,对台风路径及强度预报效果的提高也有正效应.

| Abstract: | This paper,which is on the basis of analyzing the typhoon bogus wind scheme in MM5,in order to construct the three-dimensional asymmetrical typhoon wind field model,introduces some objective factors such as the typhoon moving speed,direction and friction into constructing the asymmetric tangential wind field,and then tries to choose reasonable radial wind scheme and to consider the wind vertical structure.By comparing of the initial field of the Rananim Typhoon,the introduction of the radial winds and high ... |
