  • 摘要: 厦门大学海洋与地球学院，近海海洋环境科学国家重点实验室。摘要：本文通过分析2016年春季航次在浙江中部海域3条断面的观测资料，结果表明：（1）在断面的10~25米层左右观测到了"中层冷水"现象以及在上层观测到微弱的上升流；（2）在浙江中部海域的上层观测到较弱的上升流；（3）春季，在浙江中部海域观测到了丰富的温跃层、逆温跃层以及盐跃层现象。（4）台湾暖流水向上爬坡对跃层的变化有一定的影响，使得跃层厚度变小，跃层强度加强，但是强度并不足以冲破跃层到达表层。
    Abstract: In this study, the sectional characteristics of temperature, salinity and density off the central Zhejiang coast were analyzed using three sections of observational data in the spring of 2016. The results are as follows:(1) a cold water patch was observed in the middle layer of sections from 10 to 25 m, and a weak upwelling was observed at the upper layer near the central Zhejiang coast; (2) several thermoclines, inverted thermoclines, and haloclines were observed in the survey area; (3) the Taiwan Warm Current Water (TWCW) climbing from the slope towards the survey area affected the thermocline, making it thinner and intensified; however, the TWCW was not strong enough to break through the thermocline to reach the sea surface.
