摘要
以走航ADCP(声学多普勒海流剖面仪)在胶州湾外湾口——南起薛家岛北至团岛,对春、秋两季的大、小潮连续一日观测资料,进行垂直断面余流分析。指出湾口春、秋两季的大、小潮一日平均余流,呈现北进南出,北进余流大于南出余流,余流在湾口中间偏北地区转流,上层余流大于下层余流,大潮余流大于小潮余流,秋季余流大于春季余流。
Residual current is analysed from ADCP data observed in cruises along the section from Xuejiadao at its south end to Tuandao at its north across the Jiaozhou Bay mouth. The ADCP cruises are repeated respectively during the neap tide and during the spring tide, and not only in spring but also in autumn. It is shown that the diurnal average of the residual current appears inflow in the north of the section while outflow in the south. The inflow is stronger than the outflow. The residual current direction is reversed at a short distance north of the central location of the bay mouth. The residual becomes stronger in the upper layer than in the lower, stronger during the spring tide than during the neap tide, and stronger in autumn than in spring.
