| 摘 要： | 根据珠江口外沿岸海域2006年夏季(7-8月)及冬季(2006年12月-2007年1月)航次的CTD调查资料,分析了调查海域夏季与冬季的温度、盐度分布,温度、盐度、密度跃层特征及其与上升流、中尺度涡旋和海流的关系.结果表明:1)夏季调查海域冲淡水扩展、上升流、中尺度涡等现象在温度、盐度分布中都有很明显的表征,并对跃层分布有显著的影响,形成了复杂的跃层类型;在冲淡水扩展的影响下,还形成了双跃层与障碍层现象.2)冬季海水混合剧烈,沿岸浅水区域跃层现象不明显,在陆坡深水区存在跃层现象.

| Abstract: | Based on the data observed during the summer and winter cruises in 2006,the authors analyze the distributions of temperature and salinity off the Pearl River Estuary,the characteristics of thermocline,halocline and pycnocline as well as their relations to upwelling,mesoscale eddies and currents.The results show that:(1) strong thermocline,pycnocline and halocline exist in summer and are strongly affected by the diluted water,upwelling and eddies;in particular,the spreading of the diluted water leads to the ... |
