图8. 海表温度异常（2°N~2°S纬度带平均）的时间—经度断面^[47]
时间：第15年7月至第17年7月；经度：150°E~90°W；（a）控制试验结果；（b）扰动试验结果；黑色实线表示29 ℃等温线；该试验基于耦合数值模式进行，大气和海洋环流模式分别采用Météo-France气候模式和Ocean PArallélisé（OPA）模式。海洋模式选用混合参数化方案，通过调整温盐层结来调整混合的强度。控制试验：当计算浮力频率（N²）时，温盐剖面全部使用；扰动试验：当计算N²时，只使用温度剖面，忽略盐度的贡献，该方案可有效消除障碍层的影响

Fig.8. Time-longitude sections of sea surface temperature anomalies averaged between 2°N and 2°S^[47]
Sea surface temperature anomalies in the region of 150°E~90°W from July of year 15 to July of year 17 for the (a) control and (b) perturbed experiments. Black solid line is the 29 ℃ isotherm. The AGCM used in the study is derived from the Météo-France climate model. The OGCM is based on the Ocean PArallélisé（OPA）model. The OGCM model used the vertical mixing scheme，in which the dissipation of the density gradient is related to the Brunt-V?is?l? frequency(N²). Both temperature and salinity profiles are considered to compute the N² in control experiment. Only temperature profiles in the N² computation in perturbed experiment
