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

这个项目是为了研究北太平洋亚热带环流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率将与使用普林斯顿等平模式的数值计算进行比较。沿着北部边界，假设这是模态水形成的地方，模态水可以携带来自大气强迫的信息进入海洋内部。将使用嵌入大块混合层的等压模式来研究水柱中热含量的变化以及这些变化是否会在以后的时间影响海表温度。在环流的南边界，数值模式将用于研究这种响应是否是由于浅滩性温跃层与混合层中的浮力强迫的相互作用。目标是提高模式性能和对地表观测的解释。在用观测证实模式的准确性之后，该模式将用于将分析扩展到比卫星测量可获得的更长的时间尺度。

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.
