摘要

摘要: 将一种新型湍流通量参数化方案代入到大气环流模式CAM3中,对比分析了模式改进前后模拟的风应力、感热通量、潜热通量和降水的全球分布,以及风应力、潜热通量和降水的纬向平均。结果表明:改进后模式的模拟结果更接近ERS、ERA40湍流通量数据和CMAP综合降水数据,其中对西风带上洋面风应力、亚洲季风区的潜热通量和降水改进明显。由于该新型湍流通量参数化方案直接由整体理查逊数、空气动力学粗糙度和热力学粗糙度参数化稳定度参数,避免了通过循环迭代计算Obukhov长度,计算效率得到提高。

Abstract: A new turbulent flux parameterization scheme has been incorporated into the Community Atmosphere Model version3 (CAM3). The global distribution of turbulent fluxes and precipitation, and the zonal means of latent heat flux and precipitation simulated by CAM3 coupled with the new scheme are compared to the counterparts simulated by the original CAM3. The results show that the outputs of the improved model are much more closely to ERS, ERA40 turbulent data and CMAP data than those of the original CAM3 model, especially the wind stress in the Northern Hemisphere trade wind region, and the latent heat flux and precipitation in Asia monsoon. Because the Obukhov stability parameter is parameterized directly by using bulk Richardson number, aerodynamic roughness length, and heat roughness length, the calculate efficiency increased.
