海洋中的天气式涡旋

将由海洋中各物理过程产生的海水特性分布非均匀性，分为小、中、天气式和全球4种时、空尺度。对比副势带急民生罗斯贝波变形半径，阐明海洋天气式涡旋小于和慢于大气中的数十倍。对比在高空锋带下方，低怪大气锋中出现地面涡，揭示海洋蛇曲中不产生高空锋带类似物及近海底锋；大洋中自由涡虽能集中于海洋上半部，便与大气中低空正、反气旋正相反。因而，锋流环和洋中涡能对局地天气起作用，流环能成为海洋子午向热传递的重要机制。

SYNOPTIC EDDIES IN OCEAN

The inhomogeneous distribution characters of sea water is classified into 4 kinds, namely, small-scale, mesoscale, synoptic and global scale. As compared with Rossby deformation radius in atmospheric jet current synoptic eddies in ocean are ten times as small in their dimensions and ten times as slow as those in atmosphere. Meanders in ocean can not be analogs of atmospheric high-altitude front zones and near-bottom front though free synoptic eddies may concentrate in ocean upper half. They are in contrast to atmospheric low-level cyclones and anticyclones as compared with generation of near-ground eddies under high-altitude front zones. Frontal rings and eddies in open ocean exert effect on local weather, and rings are important to meridinal heat transfer in ocean.
