THE VARIATION AND MOVEMENT OF A KIND OF EDDIES IN SHELF SLOPE WATER

Considering the characteristics of the time and space scales of the eddies we established a qua-si-static and quasi-geostrophic model to describe their variation and movement in shelf slope water. The analytical solution revealed the main properties of the variation: slow expansion and faststagnation processes and the law of the eddy motion affected under the background field. All theo-retical results are proved by satellite image measurements.     

陆坡水域涡旋的运动及变化

基于测量的时空尺度特征,我们建立了一个描述涡旋在陆坡水中变化和运动的准静态准地转模式。这个模式的解析解揭示了涡旋变化的膨胀和旋转特征以及涡旋在背景流场和总涡度场作用下的运动规律。所有结果都得到卫星图片测量数据的定量证实。
