An Introduction to the Coupled Model FGOALS1.1-s and Its Performance in East Asia

Advances in atmospheric sciences 2010年第5期27卷 1131-1142页

The spectral version 1.1 of the Flexible Global Ocean–atmosphere–land System （FGOALS1.1-s） model was developed in the state key laboratory of numerical {4. for {4. sciences and Geophys- ical fluid dynamics at the institute of atmospheric physics （LASG/IAP）. This paper reports the major modifications to the physical parameterization package in its {4. component, including the radiation scheme, convection scheme, and cloud scheme. Furthermore, the simulation of the East Asian Summer Monsoon （EASM） by FGOALS1.1-s is examined, both in terms of climatological mean state and interannual variability. The results indicate that FGOALS1.1-s exhibits significant improvements in the simulation of the balance of energy at the top of the atmosphere： the net radiative energy flux at the top was 0.003 W m-2 in the 4. years fully coupled integration. The distribution of simulated sea surface temperature was also quite reasonable, without obvious climate drift. FGOALS1.1-s is also capable of capturing the major features of the climatological mean state of the EASM： major rainfall maximum centers, the annual cycle of precipitation, and the lower-level monsoon circulation flow were highly consistent with observations in the EASM region. Regarding interannual variability, simulation of the EASM leading patterns and their relationship with sea surface temperature was examined. The results show that FGOALS1.1-s can reproduce the first leading pattern of the EASM and its close relationship with the decaying phase of the ENSO. However, the model lacked the ability to capture either the second major mode of the EASM or its relationship with the developing phase of the ENSO.

积雪因为其特定的属性在气候变化和水文循环中扮演着重要角色,在大气和陆面之间起到了调节能量和水交换的显著作用,而陆面驱动数据的质量直接决定着模式对积雪的模拟效果。本文采用CLDAS(CMA Land Data Assimilation System)和改进后的降水驱动(CLDAS-Prcp)分别驱动Noah3.6陆面模式对积雪变量进行模拟,并对中国主要的积雪区东北区域、新疆区域、青藏高原区域的积雪覆盖率、雪深、雪水当量的模拟效果进行了评估。结果表明,CLDAS-Prcp改善了原有驱动在冬季由于低估降水所造成的模拟积雪量偏少的情况;东北区域模拟结果与观测的时间变率最为一致,积雪覆盖率、雪深、雪水当量的相关系数分别为0.4.,0.78,0.93;而雪水当量的改进效果最明显,均方根误差和偏差分别减小了54.8%和83.1%,相关系数提高了0.4.;同时,CLDAS-Prcp不仅能反映积雪变量的年际变率,而且能够较准确地反映出强度较大的突发降雪事件。

基于一个全球海-冰-气耦合模式的数值模拟结果,选取冬季格陵兰海海表面温度(SST)、海冰密集度、海表面感热通量等物理量以及3个相关区域海平面气压分别作经验正交函数展开,取第一模时间系数作相关分析。结果表明,上一年海冰密集度偏大(小)与来年的SST偏低(高)相联系,但二者同期相关性最大。当海气热通量交换变化超前一年时,其与SST相关性最大。模式最低层大气温度与海洋表面热通量之间的同时相关性最大,冬季模式最低层气温偏高(低)与海洋表面失去的感热、潜热通量偏少(多)相联系。气温、比湿都和冰岛低压区及格陵兰海的海平面气压相关性最强,冰岛低压气压偏低(高)与模式最低层气温和比湿偏高(低)相联系。所以,在海-冰-气年际尺度的相互作用中,主要关系是大气环流调整造成大气中云量和低层气温、湿度变化,进而影响海气界面上的通量交换,造成SST的变化。SST变化决定着海冰范围及海冰密集度的变化,但海冰变化时通过相变潜热的释放或吸收反过来对SST变化有较明显影响。

针对我国陡峭地形数值预报难题,本文在国际先进WRF(Weather Research and Forecasting)模式动力框架中引入阶梯地形垂直坐标,以期为改进复杂地形区域数值天气预报提供模式发展可选方案。设计气柱质量变换方法,实现阶梯地形和追随地形两种垂直坐标下动力方程组的形式一致,从而简化方程组离散及程序实现的复杂过程。阶梯地形的构造借鉴了AREM(Advanced Regional Eta-coordinate Model)的设计思路,即首先构造参考大气,而后定义阶梯地形网格特征量,最后进行阶梯地形表达。在Eta坐标下的WRF动力框架搭建完成后,采用山脉波理想试验和实例试验对新动力框架的正确性和有效性进行了检验。结果表明:由于阶梯地形固有的孤立分布特征,可造成不同台阶处气流的分离,从而使得阶梯地形在较粗垂直分辨率情形下,不能很好模拟山脉波;但如果垂直分层足够精细,或模拟时间足够长,可通过减弱气流分离现象或调整气流分布状态,对地形波进行有效刻画。

以位于青藏高原与黄土高原及陇南山地过渡带的甘南藏族自治州为例,基于考虑土壤冻融界面变化的陆面过程模式研究了1979-2012年冻土变化及水资源与生态系统碳通量对气候变化的响应。结果表明,甘南州气候态多年冻土面积约1. 5×104.m2,季节性冻土约占2. 5×10~4.m^2,多年冻土最大融化深度呈增加趋势,季节冻土最大冻结深度逐渐减少,整体上冻土正随着气温上升逐步退化;尽管降雨有所增加,而气温上升引起的蒸散发增加也可能是产流减少的原因之一,其中多年冻土区更为敏感,水热变化增减率较季节冻土区大;生态系统碳循环方面,北部主要表现为碳源,南部则表现为碳汇,升温促进植被生长,使得进入生态系统的碳呈略微增加的趋势,尽管总初级生产力(GPP)与净初级生产力(NPP)呈增长趋势,但植被碳利用效率逐步减小,表明气候变化背景下生态系统固碳能力有所退化;最后经多元回归分析可知,气候变化在多年冻土区可以解释66%的NPP变化与31%的生态系统净交换量(NEE)变化,而在季节冻土区则能解释4.%的净初级生产力变化。
