Dynamics thermocline

With these stipulations, the model reduces to one more variable than there are relationships. Therefore, if temperature is considered constant, the model would become invariant otherwise we may consider a dynamic situation with temperature varying independently (as a function of meteorological conditions, heat flow, etc.). The actual temperature distribution of the Great Lakes (except for Lake Erie and shallow areas of other lakes) is quite limited relative to volume distribution, and to a first approximation it approaches a constant of about 5°C. This conclusion may be readily ascertained by realizing the typical depth of water above the thermocline (where there is a temperature gradient) is from 10-20 meters, whereas depth equivalent to water below the thermo-... 

The dynamics behind the Kelvin wave front changes completely. The divergence of the Ekman offshore transport is balanced by the divergence of the coastal jet in the surface layer and the divergence of the Ekman compensation current in the sub-thermocline layer is balanced by the longshore divergence of a coastal undercurrent flowing in opposite direction to the upper layer coastal jet.

This chapter has presented a theoretical derivation of continuous particle size distributions for a coagulating and settling hydrosol. The assumptions required in the analysis are not overly severe and appear to hold true in oceanic waters with low biological productivity and in digested sewage sludge. Further support of this approach is the prediction of increased particle concentration at oceanic thermoclines, as has been observed. This analysis has possible applications to particle dynamics in more complex systems namely, estuaries and water and waste-water treatment processes. Experimental verification of the predicted size distribution is required, and the dimensionless coeflBcients must be evaluated before the theory can be applied quantitatively. 

Dynamics of the Mixed Layer and Thermocline of the South China Sea... 

The thermocline was ventilated in the NSCS, which was accompanied by the occurrence of potential vorticity with a specific circulation pattern. The thermocline ventilation is a seasonal phenomenon in the SCS actually. The potential vorticity in winter has a high value center and its distribution looks like a thin and fiat ellipsoid. Around the edge of this center, a horizontal circulation movement can be tracked. Water subducted into a thermocline from the mixed layer moves southward in the path of the cyclone along the edge of a seasonal potential vorticity pool. Research shows that signals in terms of the monthly temperature increment seem to come from the intrusion of the Kuroshio into the SCS. These show that seasonal variation in the SCS can deeply effect the thermocline. Thus, a study of the SCS upper circulation should include thermocline dynamics. Moreover, research into the dynamics of the thermocline and the mixed layer can help interpret the seasonal variation in the SCS circulation.
