The emergence of new media represented by internet and mobile phones overcomes time and geographicalboundary, while also supports traditional media to complete transmitting information.
Using the improved boundary layer model, under horizontal homogeneous geographical conditions, the nonconstant wind and temperature fields have been simulated numerically.
利用改进的边界层模式,对平坦地形条件下的非定常边界层风温场进行了数值模拟。
