摘要

全球云分辨模式(GCRMs)是一种明确计算云系统增长的新型大气环流模式，具有精细的空间分辨率，目前已经开发了10多个GCRMs。本文综述了云微物理在GCRMs中的应用，并介绍了GCRMs的最新进展和研究。重点介绍了非流体静力二十面体大气模型(NICAM)的研究进展。由于GCRMs涉及气候学和气象学，因此建立GCRMs云微物理方案是一个具有挑战性的问题。简要介绍了NICAM中云微物理方案和云辐射耦合的发展历史。此外，还介绍了利用卫星模拟器的分析技术的最新进展。多光学传感器的组合使用使我们能够在不人工调谐的情况下约束云微物理中的不确定过程。因此，NICAM中使用的云微物理方案自然地代表了云系统，因此，辐射预算很好地平衡，几乎没有优化。最后，介绍了一颗新的卫星和一项地面验证活动，为今后的工作做准备。

Cloud Microphysics in Global Cloud Resolving Models

ABSTRACT Global cloud resolving models (GCRMs) are a new type of general circulation model that explicitly calculates the growth of cloud systems with fine spatial resolutions and more than 10 GCRMs have been developed at present. This work reviews cloud microphysics schemes used in GCRMs with introductions to the recent progress and researches with GCRMs. Especially, research progress using a pioneer of GCRMs, Nonhydrostatic ICosahedral Atmospheric Model (NICAM), is focused. Since GCRMs deal with climatology and meteorology, it is a challenging issue to establish cloud microphysics schemes for GCRMs. A brief history of the development of cloud microphysics schemes and cloud-radiation coupling in NICAM is described. In addition, current progress in analytical techniques using satellite simulators is described. The combined use of multi-optical sensors enables us to constrain uncertain processes in cloud microphysics without artificial tuning. As a result, cloud microphysics schemes used in the NICAM naturally represent cloud systems, and hence, the radiative budget is well balanced with little optimization. Finally, a new satellite and a ground validation campaign are introduced for future work.
