Marotzke混合的理论方法，简化的数值模式和理想化的海洋环流模式将被用来理解边界混合在确定积分性质和温盐环流（THC）的旋转动力学的作用。特别感兴趣的是下列问题：（1）风和浮力强迫以及边缘混合如何决定THC的强度和动力学;（2）可变浮力强迫对混合层演变、纬向平均密度梯度和THC有什么影响;以及（3）通过地形或半球或海洋盆地之间的混合不均匀性的影响。
英文摘要
Marotzke A mix of theoretical approaches, simplified numerical models and an idealized Ocean General Circulation Model will be used to understanding the role of boundary mixing in determining integral properties and the rotating dynamics of the thermohaline circulation (THC). Of particular interest are the following questions: (1) how do wind and buoyancy forcing, together with mixing at the margins, determine the strength and dynamics of the THC; (2) what are the effects of variable buoyancy forcing on mixed layer evolution, the zonal mean density gradient, and hence the THC; and (3) what the effects of inhomogeneities in mixing, either through topography or between hemispheres or ocean basins.
