1987年7月份的温、盐分布特征表明:夏季本海区表层水向外海扩散,底层水则向岸边涌升。 调查期间,因风力和缓,上匀和层的厚度由浅水区的0m逐渐增大到外海的30m。温、盐密度跃层的强度在浅水区大,而在深水区则较小。温度和密度跃层的厚度分布为:由浅水区的小于30m增至深水区的大于90m;而盐度跃层厚度则由浅水区的大于40m逐步向外海减至10m左右。本海区的跃层分布主要与天气状况、水团配置以及环流有关。 温度和盐度跃层的周日变化明显,其强度和厚度均有一定变化幅度。
The characteristics of temperature and salt in July 1987 showed that the surface water in this area of the sea spread to the outer sea in summer and the bottom water rises to the shore. During the survey, due to the gentle wind, the thickness of the upper layer and the layer gradually increased from 0 m in the shallow water area to 30 m in the open sea. The strength of the thermocline and salt-density thermocline is large in the shallow water area and smaller in the deep water area. The thickness distribution of temperature and density thermocline increased from less than 30m in shallow water area to more than 90m in deep water area, while the thickness of saltwater thermocline gradually decreased from about 40m in shallow water area to 10m in outer sea. The thermocline distribution in this area is mainly related to the weather conditions, water mass configuration and circulation. Changes in temperature and salinity thermocline obvious changes in the intensity and thickness have a certain extent of change.
