摘要
本文使用一个非线性、非定常二维数值模式,考虑双重作用面下,即地表面和城市覆盖层顶两个表面,夜间城市边界层的发展、演变情况。模拟结果表明,夜间城市覆盖层削弱大气层结的稳定度,并在市中心覆盖层高度内形成一个小冷岛。
In this paper, we use a non-linear and non-stationary two-dimensional numerical model,in which the affect of the urban cover layer is considered,in order to study the evolution of the urban boundary layer. We get the result that in the night the urban cover layers weaken the stability of the atmosphere and form another cold island at the height of the UCL
