【摘要】 无论冬季还是夏季,吕宋海流都是南海中、北部海盆尺度的气旋式环流的东翼,也是一支较强的深层海流;吕宋海流西部吕宋涡充分发展,空间尺度为400 km左右,也是南海中部深层水中重要流涡之一.南海中北部气旋式环流是吕宋海流存在的主要动力因子,季风的影响是吕宋涡旋形成的重要外在因素,夏、秋季黑潮水大量入侵,也强化了吕宋海流和吕宋涡旋运动,而上升流的形成可以进一步强化吕宋海流与吕宋涡旋.更多还原

【Abstract】 Luzon Current is a large scale eastern boundary current of the general circulation in the northern and central South China Sea (SCS). It is a deep current. There is a well - developed Luzon cyclonic gyre (LCG) to the west of the Luzon Current. The LCG is an important deep circulation feature in the central SCS with a size of several hundreds of kilometers. Mechanism of the Luzon Current and the LCG are as follows: cyclonic circulation with basin scale is main factor to form Luzon Current. The influence of seasonal winds is important factor to form the LCG. Kuroshio intrusion enhances the Luzon Current and the LCG. After forming of upwelling, baroclinic influence enhances the Luzon Current and the LCG in summer and autumn.更多还原
