当今气候系统模式发展的重要趋势之一,是通过提高模式的空间分辨率,改进对气候系统中多尺度相互作用过程和极端事件的模拟能力.过去5年里,中国科学院大气物理研究所发展并完善了 25 km分辨率大气环流分量模式FAMIL2.2、1/10°分辨率海洋环流分量模式LICOM3.0,并以此为基础建立了高分辨率气候系统模式FGOALS-f3-H.利用上述高分辨率模式,开展了大量的数值模拟试验和预报/预测研究,其中包括国际耦合模式比较计划第六阶段(CMIP6)的高分辨率模式比较子计划(HighResMIP),建立了海洋环流预测系统(LFS)等.初步评估分析表明,相对于低分辨率模式,高分辨率模式对气候平均态和气候变率的模拟能力均有明显改进.其中高分辨率大气环流模式可以更好地模拟台风、极端降水事件,高分辨率海洋模式可以更好地模拟海洋中尺度涡旋和西边界流,而高分辨率耦合模式则可以更好重现中尺度海气相互作用过程、热带不稳定波动(TIW)等事件.
Review of the Development and Application of the High-Resolution Climate System Model FGOALS
Currently,one of the major trends in the development of climate system models is the improvement of the simulation capability for multiscale interaction processes and extreme events in the climate system.This enhancement is mainly achieved by increasing the spatial resolution of these models.Over the past five years,scientists from the Institute of Atmospheric Physics(IAP)at the Chinese Academy of Sciences have developed and improved the 25-km resolution atmospheric circulation model"Finite Volume Atmosphere Model of IAP LASG version 2.2"(FAMIL2.2).Furthermore,they have improved the 1/10° resolution ocean circulation model"LASG/IAP Climate system Ocean Model version 3.0"(LICOM3.0).These advancements have culminated in the establishment of the high-resolution climate system model"Flexible Global Ocean-Atmosphere-Land System Model version f3-H"(FGOALS-f3-H).These high-resolution models have been used in many numerical experiments for climate simulations and forecasts/predictions.Their applications include the high-resolution model comparison project(HighResMIP)of the sixth phase of the international Coupled Model Inter-comparison Project(CMIP6)and the establishment of an ocean circulation prediction system known as the LICOM Forecast System.Preliminary diagnoses and analyses show that compared to their low-resolution counterparts,high-resolution models can better simulate mean climatology and climate variability.In particular,the high-resolution atmospheric model can better simulate typhoons and extreme precipitation events.Furthermore,the high-resolution oceanic model can better simulate the western boundary currents and mesoscale eddies.Finally,the high-resolution coupled model can more accurately reproduce mesoscale sea-air interaction processes and tropical instability waves.
