Proehl9900848Funding is provided to try to validate recent theories on instability dynamics in the tropical oceans. The motivation for this undertaking is the existence of a perfectly matched set of data obtained during a cruise of opportunity in the instability wave region of the eastern tropical Pacific in late august 1994. The importance of this data set arises from the very fortuitous timing of the cruise, one week prior to the onset of tropical instability waves as viewed fromsatellite observations. Given the rapid e-folding time of these waves (2-3 weeks), this equatorial snapshot is our best view to date of a mature, unstable background state just before the presence of the waves has significantly modified its characteristics. This unique data set will be analyzed an utilized along with appropriate satellite imagery to realistically configure and run stability models of the equatorial region.

Proehl 9900848提供资金，试图验证热带海洋不稳定动力学的最新理论。进行这项工作的动机是1994年8月下旬在东热带太平洋不稳定波区进行机会巡航时获得了一套完全匹配的数据。这套数据的重要性来自于非常偶然的巡航时间，从卫星观测来看，这是热带不稳定波开始前一周。考虑到这些波的快速e折叠时间（2-3周），这张赤道快照是我们迄今为止对成熟、不稳定背景状态的最佳观测，就在波的存在显着改变其特征之前。将对这一独特的数据集进行分析，并将其与适当的卫星图像一起沿着加以利用，以实际配置和运行赤道地区的稳定性模型。
