根据在渤海石油平台上进行的为期两周的温跃层专题观测资料,对温跃层深度、上下两层海水的温度和盐度进行了数值模拟。本模式是以Stigebrandt模式为基础,并根据研究海区的特点作了重要的补充。模拟结果与实际符合良好。证明潮与风产生的联合卷挟作用,能产生很强的贯穿跃层的海水交换与混合。它使浅海夏季温跃层以下海水温度升高,并使上层海水营养盐得到补充,对海洋物理环境以及对海洋生物具有重要意义。 Based on the observations of the thermocline over a period of two weeks carried out on the Bohai Oil Platform, the temperature and salinity of the thermocline depth and upper and lower seawater layers were numerically simulated. This model is based on the Stigebrandt model and complements the characteristics of the study area. The simulation results are in good agreement with the actual ones. It is proved that the joint coercion of tide and wind can produce a strong exchange and mixing of seawater across the thermocline. It increases the temperature of the seawater below the thermocline in the shallow sea in summer and supplements the nutrients of the upper seawater, which is of great significance to the marine physical environment and to the marine life.
