Observational analysis on 3-D distribution and seasonal variation of thermohaline characteristics in the Zhanjiang Bay

  • 摘要: 利用2017年1−12月的现场观测数据,分析了湛江湾温盐的三维空间结构及季节变化特征。结果表明:(1)2017年湛江湾各站位年平均温度为23~27℃、盐度为19~27、位势密度为11~17 kg/m3、浮性频率(N2)约为10−5~10−2 s−2。浮性频率的垂向结构及水平分布与温度分布类似,而密度则与盐度的变化趋势几乎一致;(2)温度季节变化明显,夏季最高,秋季次之,冬季最低,冬夏温差最大达15℃,而盐度季节平均值相当。相较于季节引起的变化,涨落潮对温度以及盐度影响较小。温度跃层夏季最强,10 m处温度最大梯度可达到0.7℃/m,春秋季温跃层抬升至5 m附近,冬季水体上下混合均匀。夏季和秋季存在明显的盐跃层,盐度梯度最大可达到1.1每米。跃层上下温盐的季节变化规律一致;(3)水平分布上,从湾顶区、湾颈区、大堤区、浅滩区到湾口区,温度递减,盐度递增,湾顶区和湾口区平均温度差为2.3℃,盐度差为2.7。θ-S图分析显示,不同季节水体呈现为不同的温盐条带,湾口区基本为低温高盐水体,而湾顶区基本为高温低盐水体,其他区域水体介于上述两者之间。
