摘要
以台风“米娜”(201918)为试验对象,利用WRF模式及其3DVAR同化系统对海洋2B卫星和中法海洋卫星散射计海面风资料分别和同时进行同化,设计3组同化试验,对照控制试验,分析了同化不同卫星散射计海面风资料对台风模拟的影响。试验结果表明:对于台风路径模拟,3种同化方案的结果均有较明显的改善;对于台风强度模拟,3种同化方案的效果均不明显。
In this paper,taking typhoon "Mitag"(1918) as an example,the WRF model and its 3DVAR assimilation system are used to analyze the influence of assimilating different sea surface wind data of different satellite scatterometers on typhoon simulation.Three groups of assimilation experiments are designed by assimilating the scatterometer sea surface wind data of HY-2B satellite and China-France Oceanography satellite separately and simultaneously.The experimental results show that the simulation results of typhoon track could be significantly improved by using the three assimilation schemes,while the simulation results of typhoon intensity are not significantly improved by using the three assimilation schemes.
