| 摘 要： | 本文用改进的Mass-Dempsey一层中尺度模式,模拟江汉平原附近梅雨期4种典型低空流型影响下的地表流场,发现低空流型对地表风场有重要影响.当低空切变线控制时平原地表有辐合系统新生发展,而其它流型控制时地表只维持辐散流场,模拟结果还表明该地地面风场有明显的日变化.

| Abstract: | By using the improved one -level mesoscale model developed by Mass, C. F. and Dempsey, D. F., the surface wind fields responsed to four kinds of low level patterns are simulated over Jianghan Plain during the mei -yu season. It is shown that the surface flow depends on the variance of patterns and the convergence system at near the ground surface may be out -growth and develop only when the shear-line occurs over the plain. Otherwise, the divergence fields will appear. Also, the diurnal variation of the surface current is very evident in the simulation. |
