摘要
利用美国NCAR中心的天气研究与预报模式WRF(WeatherResearchandForecastModel),对金塔绿洲的环流场、温度场及湿度场结构及其日变化进行了较为全面细致的模拟研究,WRF模式很好地模拟出了绿洲—沙漠环流的日变化特征和这种局地热力环流的空间结构,模拟再现了绿洲"冷岛效应"和邻近绿洲的沙漠"逆湿"等边界层特征,模拟还发现了白天绿洲湿度场"凹型槽"式分布的特征。
The characteristics of circulation, air temperature and humidity of Jinta oasis are simulated by WRF model, which is the newest weather research and forecast model of NCAR. The results show that the WRF model has good quality in simulating the characteristics of daily variation and space structureof oasis-desert circulations. The simulated results reappea !the cold island effect' of oasis and !inversion humidity phenomenon' of the desert which is near to the oasis. And also the feature of low wet region of oasis humidity field on daily time is found out by the simulation.
