摘要本研究探讨了国家大气研究中心社区气候模式（CCM 3）的气候模拟的响应，张和McFarlane对流参数化模式中的介绍。结果表明，在CCM3中，热带对流系统，特别是西太平洋暖池的模拟地面气候，显着改善，产生更好的协议与最近的观测。由于更好地模拟了表层流场，以往模式模拟热带太平洋表层蒸发、表层风应力的系统偏差得到了明显的减小。实验使用相同的初始和边界条件，但不同的对流计划，进行隔离的对流计划的作用，并了解对流和对流大气中的大尺度环流之间的相互作用。最后，对西太平洋暖区的试验结果进行了比较。
Abstract This study examines the response of the climate simulation by the National Center for Atmospheric Research Community Climate Model (CCM3) to the introduction of the Zhang and McFarlane convective parameterization in the model. It is shown that in the CCM3 the simulated surface climate in the tropical convective regimes, especially in the western Pacific warm pool, is markedly improved, yielding a much better agreement with the recent observations. The systematic bias in the surface evaporation, surface wind stress over the tropical Pacific Ocean in previous model simulations is significantly reduced, owing to the better simulation of the surface flow. Experiments using identical initial and boundary conditions, but different convection schemes, are performed to isolate the role of the convection schemes and to understand the interaction between convection and the large-scale circulation in a convecting atmosphere. The comparison of the results from these experiments in the western Pacific warm po...
