【摘要】 根据1981年6月、8月、10月3个专题调查航次测得的温度、盐度、磷酸盐、硅酸盐、无机氮以及溶解氧数据的平面和陆架横断面分布图,对夏季出现在浙江近海的台湾暖流深层水的沿岸涌升范围、上界面、稳定状态及其时间变化规律进行了分济研究。结果指出,各个参数的等值面逐渐向上升流核心区靠拢,在水深20m层形成了“羽状”平面分布结构;通过“羽状”移动的图形,可预测涌升中心边界位置在起始、发展、消衰3个阶段的变化规律。更多还原

【Abstract】 Temperature, salinity, phosphate, silicate, inorganic nitrogen, and dissolved oxygen in sea water were measured in the coastal upwelling zone off Zhejiang during three cruises in June, August and October, 1981. The region, upper boundary, steady state, and seasonal variation about the upwelling of Taiwan Warm Current that appeared in summer are discussed according to the information of horizontal distribution and cross-shelf profiles of each parameter. The main result is that on 20 meter deep layer the upwelling center was found in terms of the characteristic structure of "plume", because the isograms of the parameters were gradually close to the center. The boundary position of he center can be forecasted in terms of a pattern of historical evolution of the "plume" while it is drifting.更多还原
