9508165 Xue This project entails the study of air-sea interaction processes along the Gulf Stream front off the North Carolina coast using a three-dimensional ocean model and a two-dimensional (vertical slice) coupled atmosphere-ocean model. The work focuses on the following specific objectives: (1) an investigation of the evolution of the atmospheric and oceanic boundary layers associated with passing winter cyclones; (2) to determine the relationship between atmospherically induced oceanic motions and the regional oceanic features, with emphasis on the Gulf Stream meanders; (3) to demonstrate the air-sea coupling process during cold air outbreaks; and, (4) to quantify the feedback effects on the mesoscale and synoptic scale motions in the atmosphere and ocean.

该项目采用三维海洋模型和二维（垂直剖面）大气-海洋耦合模型研究北卡罗莱纳海岸墨西哥湾流锋面的海气相互作用过程。这项工作的重点是以下具体目标：(1)研究与冬季气旋过境有关的大气和海洋边界层的演变；(2)确定大气引起的海洋运动与区域海洋特征的关系，重点研究墨西哥湾流的曲流；(3)论证了冷空气爆发时的海气耦合过程；(4)量化对大气和海洋中尺度和天气尺度运动的反馈效应。
