舟山渔场的水温分布特征分析

通过调查测得的数据分析了渔场水温的分布概况, 结果发现: 水平分布上, 无论冬夏, 渔场中北部始终存在1个低温区, 台湾暖流处(位置冬季偏东, 夏季偏西, 平均位置在124°E附近)存在高温水舌指向偏北, 冷暖水系交汇明显; 垂直分布上, 由于渔场岛屿众多, 海水混合作用强烈, 水温垂直梯度终年都很微弱, 即使在盛夏也很难形成强大的跃层.

Temperature Distribution in Zhoushan Fishing Ground

Based on data of the measured water temperature, this article conducts the analysis on water level distribution, finding that the water level is not directly related to the seasons, that is, the low temperature is always found in northern part of fishing ground where Taiwan warm current moves to the northern high temperature tongue. In the perpendicular direction, due to the large number of the islands in fishing ground causing mixed impacts, the water temperature is at rather low lever all the year around, even so in the midsummer.
