中文摘要: 2009年3月23日美国联邦快递公司的一架飞机在东京成田机场坠毁，事故发生的原因与当时的气象条件密切相关。利用美国新一代非静力平衡中尺度数值预报模式（WRF V2.2）对该次过程进行数值模拟，着重分析事故发生前后各种物理量的水平分布和垂直配置，并诊断分析了该时段内位温平流的分布特征。结果表明，强风发生在位温平流梯度区。强冷空气影响下形成的低空水平风的垂直切变、低层强下沉速度引起的侧风切变和地面强风是造成此次事故的主要气象原因。

中文关键词: 低空风切变，数值模拟，垂直速度

Abstract:A US FedEx cargo plane crashed and burst into flames as it landed at Tokyo Narita airport on March 23, 2009. The weather conditions of the crash are simulated and analyzed in this article. A new generation of WRF(Weather Research & Forecasting，designed in the United States) nonhydrostatic model 2.2 is used in simulating this process. The horizontal and vertical distributions of several critical physical elements before and after the crash are analyzed. Particularly, the horizontal distribution of potential temperature is diagnosed and analyzed. The result shows that strong surface wind is formed in the region of potential temperature advection gradients, and that the strong surface wind, the strong downdraft caused by the surface wind in the low level and the low level windshear are the main meteorological causes of this accident.

keywords: low level wind shear, numerical simulation, vertical velocity
