伶仃洋盐度高度层化现象及盐度锋面的研究

Numerical simulation of high resolution on the phenomenon of saline stratification in LinDinYang

根据1999年7月实测资料,首次发现珠江口伶仃洋出现盐度高度分层的现象。本文对实测资料进行了分析,并运用三维斜压模型对该区域进行了数值模拟,模型采用垂向最小0.5m的高分辨率计算模拟盐度高度分层现象。模拟结果与实测资料基本吻合,并很好的反映出伶仃洋盐度高度层化现象整体分布,给出了计算模拟的盐度锋面。

Based on the data of measure in July, 1999, the phenomena of the highly saline stratification was discovered in the Pearl delta sea for the first time. After analyzing the measured data, we apply the three-dimensional baroclinic model to this area. A high resolution model was applied, to simulate the high saline stratification phenomenon, which have a minimum about 0.5m in the vertical direction. The result of simulation agree with the measured data and the simulation result also show the integer distribution of saline stratification phenomenon of the sea water in the Pearl delta ocean.
