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。 A modified model of the original equation (Danard mode) was used to conduct numerical experiments and numerical simulations of the surface wind field over the Taiwan Strait. First, under some ideal conditions, the effects of ground pressure field, topography, friction and heating on the wind field on the ground are studied. It is pointed out that the ground pressure field determines the basic distribution of the wind field on the ground; the friction plays an important role in the difference of the wind speed between the land and the land; the topography shows weak shunt and flow blocking effect; And the actual wind field under the control of the northeast airflow is numerically simulated with good results.
