摘要

摘要: 利用三维高分辨率有限体积的近海海域模型FVCOM来分析2001年秋季期间风作用对坦帕湾区域盐度平衡的影响。为了区分风的影响，分别设计了两个实验：一个由潮汐和河流作为驱动，另一个由潮汐、河流以及风场共同驱动。结论如下：首先，风作用会使盐度产生变化，能够明显地使坦帕湾内的盐度增加，并导致水平和垂直方向上盐度梯度的减少；随后，本文分析了坦帕湾区域内的盐度平衡，主要的盐度平衡来自于全部（水平和垂直方向上）平流的盐度流量分歧以及除去海峡底部的垂直方向上盐度流量分歧；最后，对由风引起的盐度变化进一步进行分析，结果表明风作用不能改变盐度平衡地位的相对重要性，由风引起的盐度平衡改变高度依靠于特殊的地形，除此之外，全部平流盐度流量分歧和垂直散布盐度通量分歧能够抵消，并且两者都远大于水平散步盐度流量分歧。

Abstract: A three-dimensional, high resolution, Finite Volume Coastal Ocean Model (FVCOM) is used to diagnose the influences of winds during the fall of 2001 on the salt balance of the Tampa Bay. To distinguish the wind effecting, two experiments are designed:one is driven by tides and rivers; the other is driven by tides, rivers and winds. First, the salinity change induced by wind is provided. Wind forcing can significantly increase the salinity inside the Tampa Bay, along with decreases of horizontal and vertical salt gradients. Subsequently, the salt balance principles are detailed addressed. The primary salt balance is between the total (horizontal plus vertical) advective salt flux divergence and vertical diffusive salt flux divergence except at the channel bottom where horizontal diffusive salt flux divergence comes into play. At last, the salt balance variation induced by winds is further addressed. Wind forcing does not change the relative importance of salt balance terms. The variations of the salt balance terms influenced by winds are highly dependent on the specific locations. Besides, the variations of the total advective salt flux divergence and the vertical diffusive salt flux divergence are nearly couterbalance, and both of two terms are much greater than that of the horizontal diffusive salt flux divergence.
