Cenedese - 0095427The role of geostrophic eddies in setting the stratification and meridional transport of a circumpolar current will be explored through experiments in an unique laboratory configuration. Buoyancy flux and mechanical mixing will be allowed to act simultaneously to develop a thermocline and eddies. Preliminary efforts are complete. The portion of buoyancy flux/'stress' parameter space to be investigated includes the Antarctic Circumpolar Current characteristics. Later studies will include a 'cape' to model the effects of Drake Passage and a sloping lid in an effort to model beta plane effects.

Cenedese-0095427将通过在一个独特的实验室配置中的实验来探索地转涡在形成绕极洋流的层结和经向输送中的作用。浮力通量和机械混合将被允许同时作用于温跃层和涡旋。初步工作已经完成。浮力通量/应力参数空间包括南极绕极流特征。随后的研究将包括一个用来模拟德雷克航道效果的‘斗篷’和一个倾斜的盖子，以努力模拟测试版飞机的效果。
