中文摘要:
      应用ECMWF有限区域模式,设计了两个数值实验以估计辐射效应对于夏季风开始的影响。对照实验包括所有的物理过程。另一个实验在模式中除去长波和短波辐射过程。比较这两个实验的结果表明:在南亚大陆上空,辐射过程增强了西南季风及其相应的垂直环流。尤其是对青藏高原上空的高原季风,辐射效应是根本性的。辐射过程增强了大陆上空的“湿”过程。较多的潜热释放反馈导致季风环流的加强。
英文摘要:
      Two numerical experiments were performed by using ECMWF limited area model in order to assess the impact of radiative processes on the onset of summer monsoon. The control experiment included all the model physics and another experiment had the radiative processes excluded. The simulated results show that:the radiative processes enhanced the monsoon currents and the associated vertical circulations over southern Asia continent, especially over Qinghai-Tibet Plateau. The build up of the "Plateau Monsoon Depresson" and the onset of Plateau rainny season are highly dependent upon the radiative processes.Through the cloud-radiation interaction, the "moist processes" were enhanced over the continent. More latent heat was released. The feedback of the physicalprocesses caused the strengthening of the monsoon circulation.
