| 摘 要： | 利用修改的一层原始方程模式(Danard模式),对台湾海峡地区地面风场进行了数值试验和数值模拟。首先在一些理想情况下,研究了地面气压场、地形、摩擦和加热对地面风场的影响。指出:地面气压场决定了地面风场的基本分布;摩擦对海陆风速差异有重要作用;地形作用表现为弱的分流和阻流作用,加热作用使风场趋于紊乱。并在东北气流控制下的实际风场进行了数值模拟,效果良好。

| Abstract: | In this paper,using a modified one-level primitive equation model ( the Danard model),some numerical experiments and numerical simulations for the surface winds in the areas of the Taiwn Strair are made First,we discuss the effects of many factors such as surface pressure fields,topography,friction and heating on the surface wind fields in some ideal cases It is shown that surface pressure fields determine the elementary distribution of the surface winds,friction has a very important impact on the variety between sea breeze and land breeze,the influence of ropgraphy is in the form of a weak airflow dctouring and blocking effect,and the wind fields become complex due to heating.Finally,we make a numerical simulation for a real wind which is controled by a northeastern airflow The results are satisfactory |
