The movement of water from the Caribbean Sea to the Gulf of Mexico is one of the largest sources of northward heat transport in the Atlantic Ocean. While in the Gulf of Mexico, some water is diverted eastward through the Florida Straits and forms the beginning of the Gulf Stream while some may be diverted into the Loop Current Eddy. Therefore, the Loop Current has a strong influence on the Gulf circulation and on Florida Current transports. Therefore, the variability of the Loop Current has a broad impact on the meteorological and oceanographic conditions within the Gulf of Mexico. The aim of this study is to provide predictability of the Loop Current between the Yucatan and the Florida Straits. Using field data analysis, theoretical and analytical models as well as results from the numerical circulation models MICOM and HYCOM, they plan to address several key issues including the eddy fluxes and their variability across the Antilles passages, the dynamical structure and the stability properties of the Caribbean Current, how different forcings affect the variability of the Caribbean Basin and the Loop Current.

从加勒比海到墨西哥湾的水运动是大西洋北向热运输的最大来源之一。 在墨西哥湾时，有些水通过佛罗里达海峡向东转移，形成了海湾流的开始，而有些则可能被转移到环电流涡流中。因此，环电流对海湾循环和佛罗里达电流的运输有很大影响。因此，环电流的变异性对墨西哥湾内的气象和海洋学条件有广泛的影响。这项研究的目的是提供尤卡坦和佛罗里达海峡之间环流的可预测性。使用现场数据分析，理论和分析模型以及MICOM和HYCOM的数值循环模型的结果，他们计划解决几个关键问题，包括涡流通量及其在整个Antilles段落中的可变性，加勒比海电流的动态结构和稳定性，如何影响货物底层和凸层的不同强度。
