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.

[0220563] clark数据分析和建模将用于了解沿美洲西海岸和南澳大利亚湾沿海洋流的年际变化，特别是那些与厄尔尼诺-南方涛动现象有关的洋流。描述这种变化的数据集包括几十年的沿海水位数据、10年的测高数据、加州沿海渔业调查数据集和加拿大line-P数据集。将要使用的模型将包括现有Clarke和Van 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，以及一个统计模型。现有理论预测赤道信号沿海岸传输，但不像观测到的那样传播。我们将探讨理论与观测之间的这种差异。
