摘要

摘要: 将海洋飞沫参数化引入到一个高分辨率、非静力中尺度WRF模式中，对0908号热带气旋Morakot进行数值模拟，探讨了海洋飞沫对热带气旋Morakot边界层结构和强度的影响。模拟结果表明:采用新参数化后，对热带气旋Morakot的强度预报有改进，但对热带气旋移动路径改进不大;其次，通过对边界层过程的改进，使得眼墙区域的平均径向风速、切向风速、温度、相对湿度、垂直风速、热通量，降水等物理量均有增强，各物理量的贡献对热带气旋Morakot强度和结构变化的影响十分重要。

Abstract: The sea spray flux parameterization scheme is incorporated into a high resolution and non-hydrostatic weather research and forecasting (WRF) model to simulate tropical cyclone (TC) Morakot (0908),and to study the effect of sea spray on boundary layer structure and intensity of Morakot. The results show that the intensity prediction of Morakot has been improved by using the new scheme,while there is no any impact on its track forecasting. Moreover,the averaged elements,such as radial wind,tangential wind,temperature,relative humidity,vertical wind,heat flux and precipitation in TC inner core region are increase by improving TC boundary layer processes. That means the contributions of all the elements have play important roles on Morakot structure and intensity change.
