摘要
该文基于水体平均存留时间的概念,数值模拟不同风场条件下胶州湾的水交换能力。结果显示:在无风状态下,整个胶州湾的水体平均存留时间为79 d,在夏季统计风场、冬季统计风场、SE风向异常大风和NNW风向异常大风条件下,整个胶州湾的水体平均存留时间相对于无风状态分别减少了15.2%、21.5%、3.8%和2.5%。异常大风持续作用一天,对胶州湾东北、西南海域的水体平均存留时间影响可达10%左右。
A numerical model is developed to investigate the effect of wind on the water exchange in Jiaozhou Bay by using the concept of average residence time（ART）. The ART of the whole bay is 79 d in the case of no wind. Under the condition of statistic SE wind, statistic NNW wind, anomalous SE wind, and anomalous NNW wind, the ART of the whole bay loses 15.2%, 21.5%, 3.8% and 2.5%, separately compared with the condition without wind. If the anomalous wind keeps working for one day, it will affect the ART of northeast corner and southwest corner up to about 10%.
