摘要
本文应用一个有限区域细网格6层大气环流模式,分析了我国干旱区灌溉对短期天气过程可能造成的影响,通过数值试验表明,灌溉将使局地下垫面对大气的潜热输送增加,上升运动和水平辐合增强,从而导致低云量和降水显著增多。
A limited-area fine-mesh 6-level general circulation model is used to study the effects ofthe irregation in Chinese drought area on short-range weather. The results of numerical ex-periments show that the latent heat from the underlying surface to atmosphere will be added,the upward motion and the horizontal convergence will be reinforced, in consequence thelower cloud cover and the rainfall will be increased through irregation in Chinese droughtarea.
