摘要
利用ｐ－σ混合坐标系原始方程５层球带模式，对７月中低纬流场进行数值模拟，重点分析近地面流场、经圈环流、纬向风随高度的变化及越赤道气流的模拟特征。结果表明，季风区和非季风区的经圈环流及纬向风的垂直分布，存在着明显的差异。并能清楚地看到海陆热力差异对大气环流的影响。
A zonal 5-layer primitive equation model in a p-σ incorporated system is used tosimulate the July flowfield at mid and low latitudes。Focus is on analysis of the simulations ofnear-surface flowfield,meridional and zonal circulations,zonal wind changing with height andcross-equatorial current.Restilts show that there is evident difference between the meridionalcirculations and vertical distributions of the zonal winds in the monsoon and nonmonsoon re-gions.The influence of land-sea thermal contrast on the atmospheric circulations is clearly re-vealed by the simulations.
