跃层

内波模型是结合非线性孤立波KdV方程解建立起来的，用于模拟发生在海洋密度跃层处具有巨大前导波和较小、较慢线性曳尾波特征的海洋内波。

在春季，表层热含量和表征台湾暖流的底层盐含量的同步提加，提高了密度跃层的强度，是中层冷水得以维持的重要因素。

In spring , the sea surface heat content increases with increasing bottom salt content to strengthen the pycnocline , which is a main factor for maintaining ICW .

20°N以南研究海域，温跃层季节变化不明显。逆温跃层主要出现在冬、春季节（10月-翌年5月）。

It reveals little seasonal variations in the study area south of 20 ° N. The inversion thermocline is found in winter and spring ( Oct. - May ) .

盐度跃层下界深度为60～100m，厚度约50m。

The lower boundary of halocline lies between 60 m to 100 m with a thickness of about 50 m.

春季，层化开始出现，上混合层厚度约5m，跃层的强度比较弱，区域差异比较小；

In spring stratification appears , mixed layer depth is about 5 meters , and the thermocline is weak .

夏季，层化加强，上混合层厚度加深至约10m，温跃层强度比较大，并且黄海强度大于东海；

Summertime , stratification strengthens , and mixed layer depth is deeper ( about 10 meters ), and the thermocline is stronger .

由于两季节层化程度的不同，营养盐跃层深度也不同，春季在30m以深，夏季为30m以浅。

The stratification depth in two seasons is different that which is below 30m in spring and above 30m in summer .

从年平均的纬向平均温度和盐度的断面分布可以看出，温跃层深度呈W型分布，在亚极地海区有一个梯度比较大的盐度锋区。

It is shown from the annual mean zonally averaged temperature and salinity distributions that the thermocline depths show a W-shaped pattern , and there is a salinity front in the subpolar sea area .

最后作为该模型的一个实用性试验，选择了美国犹他州EastCanyon水库，利用该模型探讨了温跃层对风、人流及出流变化的响应情况。

Finally , as a example of its application , this model was applied in East Canyon reservoir , Utah , USA. The efficiency of the prediction of thermocline corresponding to the wind forcings and inflow and outflow has been discussed .

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；

The distribution of thickness of the thermal and density layer increases from less than 30m in shallow water to more than 90 m in the deep water layer .

稳定性分析表明，北太平洋较大面积区域存在斜压不稳定性或正压不稳定性，有利于ENSO相关的温跃层异常信号以Rossby波形式有效地西传；

The instability analysis shows that there exists a large area with baroclinic instability or barotropic instability in the North Pacific , which helps the thermocline anomaly related to ENSO cycles propagate westward effectively in forms of Rossby waves ;

在缺乏高分辨率资料且长江径流量不大时，夏季东海浅海海区也可以运用S-T法计算温跃层和密度跃层上界深度。

The depths of the thermocline and pycnocline can also be calculated correctly by using the S-T method in the shallow shelf areas when the Yangtse River runoff is normal or less than normal .

以长江口以东H断面为例，描述了夏季溶解氧的断面分布特征，在20～30m水层出现一氧跃层，30m以下垂直分布比较均匀。

The description of DO vertical distribution in H section was done in summer with H section in the east of Yangtze estuary as an example . A layer DO occured at 20 ~ 30 m , and the vertical distribution was even below 30 m.

而其内部高浓度的PO4-P水平，更对冬季跃层消失后，整个海区PO4-P浓度的提升，发挥了巨大作用。

After the disappearance of the thermocline in winter , the higher content of PO4-P in Yc play a significant role in upgrade the concentration in the whole area .

化学要素垂直分布如温度一样出现了强跃层，并于350m层出现了异常的营养盐垂直分布，但盐度无明显跃层存在。

The vertical distribution of chemical elements emerges a strong spring layer like temperature and abnormal vertical distribution of nutrient turns up at 350m layer . However , there is not almost obvious spring layer in salinity .

在中国陆架海区调查获得的CTD资料表明，陆架区的水文要素垂直结构大都可以理想化为三层垂直结构模式：上均匀层、跃层和下均匀层。

It is shown from the CTD data collected in Chinese shelf sea area that most of vertical structures of hydrographic elements can be idealized as a 3-layer structure pattern , namely , upper homogeneous layer , thermocline and lower homogeneous layer .

温跃层的存在是底层高悬浮体含量的海水难以到达表层的主要原因V.C高；

The thermocline is the main season that the higher suspended matters in the bottom could not reach up to the sea surface .

长江径流量偏小和正常的年份，在东海的浅海海区（水深200m）运用S-T法计算的跃层上界深度与垂向梯度法的结果比较一致，都与实际跃层深度符合较好。
