摘要利用两种统计方法和一种动力学方法，在共同体气候系统模式第3版(CCSM3)中评估了大气对北太平洋海洋变率的响应。在初冬-仲冬期间，所有方法都确定了黑潮延伸区(KOE)海表面温度(SST)变暖的等值正压低响应。虽然这三种方法都捕捉到了响应的主要特征，但广义均衡反馈评估方法(GEFA)将KOE SST的影响从复杂的背景中分离出来，从而使其成为类似实践的极佳选择。
Abstract Atmospheric response to North Pacific oceanic variability is assessed in Community Climate System Model, version 3 (CCSM3) using two statistical methods and one dynamical method. All methods identify an equivalent barotropic low response to a warmer sea surface temperature (SST) anomaly in the Kuroshio Extension region (KOE) during early–midwinter. While all three methods capture the major features of the response, the generalized equilibrium feedback assessment method (GEFA) isolates the impact of KOE SST from a complex context, and thus makes itself an excellent choice for similar practice.
