| 摘 要： | 介绍了一套自行研制的室内模拟湍流系统.通过加热以及制冷手段控制水槽的顶部和底部温度,模拟暖空气均匀越过冷空气表面条件下的稳定边界层(SBL)温度场结构特征,以及平坦下垫面均匀加热条件下的对流边界层(CBL)温度场结构特征,并测量两种情况下的平均温度和热通量垂直廓线,分析对流混合层发展的演变过程.结果表明,模拟SBL和CBL的温度场结构与大气边界层的温度场结构观测结果符合较好.

| Abstract: | A self-developed laboratory simulation system on turbulent flow is introduced.The characteristics of temperature structure of the stable boundary layer(SBL)and convective boundary layer(CBL)are simulated by controlling temperature of the top and bottom of the laboratory water tank.Warm atmosphere flows through the surface of cool atmosphere uniformly to the SBL,and flat terrain surface are uniformly heated to the CBL.Vertical profiles of mean temperature and heat flux are measured in the SBL and CBL conditi... |
