Observations and Dynamics of Interannual Coastal Flows

0220563克拉克数据分析和建模将用于了解沿海流量的年际变化，特别是那些与厄尔尼诺-南方涛动现象，沿着美洲西海岸和南澳大利亚湾。 描述这种变化的数据集包括几十年的沿海水位数据、十年的测高数据、加州沿海渔业调查数据集和加拿大P线数据集。 将使用的模型将包括现有Clarke和货车Gorder模型的改进版本，包括对背景速度和倾斜分层的预期依赖性，以及一个统计模型。 现有的理论预测赤道信号沿着海岸的传输，但不是信号的传播，如观察到的。 我们将探讨理论与观察之间的这种差异。

0220563 ClarkeData analysis and modeling will be used to understand the interannual variability of coastal flows, particularly those associated with El Nino - Southern Oscillation phenomena, along the west coast of the Americas and the South Australian Bight. The data sets for characterizing this variability include many decades of coastal water level data, a decade of altimetry, the California Coastal Fisheries Investigation data set, and the Canadian line-P data set. The models to be used will include an improved version of the existing Clarke and Van Gorder model, including expected dependence on background velocity and sloping stratification, and a statistical model. Existing theory predicts transmission of an equatorial signal along the coast, but not propagation of the signal, as observed. This discrepancy between theory and observation will be explored.
