风暴作用下渤海中污染物(COD)输运的研究

SIMULATION OF THE TRANSPORTATION OF POLLUTANT COD DURING STORM SURGES IN THE BOHAI SEA

本文利用三雏POM模式，分别就潮汐作用下和风暴作用下污染物输运进行了数值模拟；比较了两种驱动下渤海内污染物榆运的差异。通过比较发现：风暴潮（尤其是寒潮）平均每年使渤海污染物总量的减少量是潮汐作用的3～4倍；每次风暴潮过程对渤海内污染物重新分布的作用与潮汐30天的作用是同量级的。所以，在研究渤海的污染物榆运时，必须考虑风暴潮的作用，否则，会产生很大的误差。

The process of transportation of COD is added into the Princeton Ocean Model. Based on the satisfactory respective simulation of the tide and the storm surges, the variation of the amount and distribution of COD in the Bohai Sea are simulated, and the two results are compared and discussed. The mean decrement of the amount of COD per year due to storm surges is 3-4 times as that duo to tide. The effect of storm surges on the distribution of COD content is as strong as that by tide of 30 days. Therefore while studying the distribution and transport of pollutants in the Bohai Sea, the role of storm surges must be taken into account.
