Description:
The thermocline model suggested by ERTEL (1953) is used to describe thin surface layers that had been observed in the Western Baltic. The layers have typical vertical scales of a few decimeters, and their temperature exceeds the temperature of the underlying water by a few tenth °C. Advection is taken into account by means of a source function (including heat sources and sinks). The special case of the mixing coefficient of heat sinks and sources being equal to the coefficient of turbulent heat conduction can be used here if the coefficients are close to the molecular coefficient of heat conduction (approx. 10-3cm 2s-1). The results show that this special case of the model is applicable here. Using the above assumption the vertical temperature distribution during the heating period can be well approximated by using coefficients (10 to 40 10-3cm2s-l) which are sufficiently close to the molecular value.
