摘    要:用修改的Nickerson等提出的中尺度模式,对我国北方夏季非均一下垫面上的边界层气候特征进行了研究。结果表明,在晴朗、静风和无扰动系统的条件下,下垫面的非均一性对边界层气候起着决定性的影响。边界层气候特征和低空急流强度与局地环流关系密切。干燥裸地上边界层内出现的逆湿现象,是由下垫面非均一的湿度场和中尺度平流共同引起的。

关 键 词:下垫面非均一性    夏季    边界层气候    逆湿

Abstract:The PBL climate characteristics over inhomogeneous underlying surface in North China for summer is studied by using the modified Nickerson’s model. The results indicate that the horizontal inhomogeneity of temperature and humidity over the underlying surface plays an important role in the boundary layer climate under conditions of clear and calm day without synoptic system disturbance. The PBL climatic features are closely related to the local circulation. A phenomenon called inversion of humidity in the PBL over a dry bare soil is ascribed to the joint of the heterogeneous humidity pattern and mesoscale advection over the inhomogeneous underlying surface
Keywords:Inhomogeneity of underlying surface  Summer  PBL climate  Inversion of humidity
