| 摘 要： | 利用湍流动能闭合方法对区域气候模式RegCM3中的边界层参数化方案进行了改进,然后利用中国东部典型旱、涝年资料进行了改进效果对比试验,并着重分析了边界层参数化方案改进对陆气相互作用的影响,结果表明:采用湍流动能闭合方法可以更合理的描述边界层的高度及其日变化,较为真实地描述边界层的物理过程,使得陆—气间通量及大气各层垂直...

| Abstract: | The planetary boundary layer scheme of RegCM3 is improved by using turbulence kinetic energy(TKE)closure scheme.The NCEP/NCAR reanalysis data of 1994/1998 are employed to test the effects of the TKE scheme on regional climate modeling.The results show that: after employing TKE closure scheme,the physical process in boundary layer can be described more realistically,and the flux between land and atmosphere can be accounted for more reasonably.The simulated precipitation and temperature are also improved to s... |
