本文建立了一个考虑层结的二维内边界层数值模式, 研究了下垫面粗糙度、温度、湿度突变引起的内边界层。结果表明: 下垫面温度突变引起的温度内边界层与下垫面粗糙度突变引起的速度内边界层具有明显的差异。

A two dimensional internal boundary layer(IBL) numerical model in which stratification is considered is developed to study IBL caused by abrupt changes of surface roughness, temperature and humidity. The results show that significant differences exist between the velocity IBL caused by the abrupt change of surface roughness and temperature IBL caused by the abrupt change of surface temperature.
