Assessment of the Southern Ocean Sea Surface Temperature Biases in CMIP5 and CMIP6 Models

Journal of Ocean University of China 2024年第5期23卷 1135-1150页

This work evaluates the performances of climate models in simulating the Southern Ocean(SO) sea surface temperature(SST) by a large ensemble from phases 5 and 6 of the Coupled Model Intercomparison Project(CMIP5 and CMIP6). By combining models from the same community sharing highly similar SO SST biases and eliminating the effect of global-mean biases on local SST biases, the results reveal that the ensemble-mean SO SST bias at 70° – 30°S decreases from 0.38℃ in CMIP5 to 0.28℃ in CMIP6, together with increased intermodel consistency. The dominant mode of the intermodel variations in the zonal-mean SST biases is characterized as a meridional uniform warm bias pattern, explaining 79.1% of the intermodel variance and exhibiting positive principal values for most models. The ocean mixed layer heat budget further demonstrates that the SST biases at 70° – 50°S primarily result from the excessive summertime heating effect from surface net heat flux. The biases in surface net heat flux south of 50°S are largely impacted by surface shortwave radiation from cloud and clear sky components at different latitudes. North of 50°S, the underestimated westerlies reduce the northward Ekman transport and hence northward cold advection in models, leading to warm SST biases year-round. In addition, the westerly biases are primarily traced back to the atmosphere-alone model simulations forced by the observed SST and sea ice. These results disclose the thermal origin at the high latitude and dynamical origin at the low latitude of the SO SST biases and underscore the significance of the deficiencies of atmospheric models in producing the SO SST biases.

圣谕宣讲的地方化过程,是一个从内容到形制、从官方到民间、从讲唱脚本到案头读本的演进过程,这一过程同时伴随着与地方性文体合流的现象。清代甘肃各地方志中对圣谕宣讲的仪式过程、讲生任用、宣讲效果等都有或详或略的记载,结合宣讲文本可以复原宣讲仪式的历史场域。圣谕宣讲仪式的表演性、宣讲文本的故事性,使其与说唱艺术类的河西宝卷合流,而劝善与实用的社会功能是二者能够合流的根本之所在。在清咸丰以后,圣谕宣讲与宝卷宣卷在主题上已经很难有一个清晰的分界标准,但不管是圣谕的“宣讲”,还是宝卷的“宣卷”都是对权威观念的传播,体现的是政治、道德、传统的声音,共同形塑了中华民族共同体意识的文化表征:忠孝、仁义、宽厚与坚韧。
