Helfrich 9616949 Laboratory experiments and numerical studies of planetary- scale flow in multiply connected domains will be conducted to examine circulation features (e.g. recirculation zones, zonal jets and flow separation) that are induced by islands and to explore the validity of the linear Island Rule developed by Godfrey. The experimental work will begin with an examination of flow in the barotropic lid- driven sliced cylinder analogue of the beta plane. A number of island geometries will be examined and the effects of stratification will be added. A companion numerical study using the Miami Isopycnic coordinate model (MICOM) will be undertaken for comparison with the experiments.

将进行多连通域的行星尺度流动的实验室实验和数值研究，以检验由岛屿引起的环流特征（如再环流带、纬向射流和流动分离），并探索Godfrey提出的线性岛屿规则的有效性。实验工作将从检查正压盖驱动的切片圆柱体模拟β平面中的流动开始。将审查若干岛屿的几何形状，并将补充分层的影响。将使用迈阿密等隐坐标模型（MICOM）进行伴随数值研究，以便与实验进行比较。
