河西绿洲效应的数值模拟研究

Numerical Simulation of Oasis Effect in Gansu Corridor

利用MM5V3.6模式,设计了一组河西绿洲存在的控制试验和绿洲变为荒漠的"去绿洲"试验;模拟分析了剔除现有绿洲影响下,背景场的环流、温度及湿度情况,同时对比分析了绿洲存在状况下,环流场及温度、湿度场的特征。通过两者的对比分析,更加清晰地再现了河西绿洲效应的特点。

Using the numerical model MM5V3.6, the control and 'removing oasis'tests have been designed and the latter has been used to simulate the wind,temperature and circulation of background field. Correspondingly, the characters of wind, temperature and humidity of control test have been simulated and analyzed. The comparative analyses clearly representthe 'oasis effect' in Gansu Corridor.
