Interaction of Dynamics and Thermodynamics along the Boundaries of the North Pacific Subtropical Gyre

该项目是为了研究北太平洋副热带气旋边界上的海洋动力学和热力学。观测到的地表高度和温度的变化将与使用普林斯顿等密度模型的数值运行进行比较。沿着北部边界，假设这是模式水形成的地方，它可以将大气强迫的信息携带到海洋内部。一个嵌入整体混合层的等周期模式将被用来研究水柱中热含量的变化，以及这些变化是否会在以后影响SST。在涡旋的南部边界，数值模式将被用来研究这种反应是否是由于浅海温跃层与混合层中浮力的相互作用所致。其目的是改善模型的性能和地面观测的解释。在用观测确认了模型的准确性后，该模型将被用来将分析扩展到比卫星测量更长的时间尺度。

The observed variability in surface height and temperature will be compared with numerical runs using Princeton isopycnal model. Along the northern boundary, the hypothesis is that this is where the mode waters are formed, which can carry information from atmospheric forcing into the ocean interior. An isopycnal model with an embedded bulk-mixed-layer will be used to investigate where in the water column heat content changes and whether these changes could affect SST at a later time. At the southern boundary of the gyre, the numerical model will be used to investigate whether this response is due to the interaction of the shoaling thermocline with buoyancy forcing in the mixed layer. The objective is to improve both model performance and interpretation of surface observations. After confirming model accuracy with observations, the model will be used to extend the analysis to longer time scales than are available from satellite measurements.
