南海北部中尺度涡与内波相遇的特征分析
Characteristics of encounter between a mesoscale eddy and internal waves in the northern South China Sea
摘要
Abstract
Based on the mooring system on the continental shelf break in the west of the Dongsha Island in the northern South China Sea, the characteristics of encounter between a mesoscale eddy(ME) and internal waves(IW) was analyzed. The internal solitary wave with a period of 20-30s and the internal tides with diurnal and semidiurnal period were found. The passing of a mesoscale eddy was depicted from sea level anomaly. The encounter of mesoscale eddy and internal wave was deduced from the time of sprint tide and thereby the abnormal change of pressure was explained. From the directions of currents caused separately by the ME and IW, we can draw a conclusion that when these two directions are opposite, the downward shake of contour of temperature will change to upward shake.关键词
