Given several different approaches to handle vertical transport of heat, mass and momentum in lakes and the air - lake interactions, a Lake Model Intercomparison Project was launched. The results from a modeling study of a thermodynamic regime of two mid-latitude shallow lakes are reported. These are Kossenblatter See, Germany (a polymictic lake with the mean depth of about 2 m), and Lake Valkea-Kotinen, Finland (dimictic, mean depth of 3 m). The capability of different lake models to develop, maintain and destroy temperature stratification and to reproduce other salient features of thermal regime of the above lakes are assessed. The heat and momentum fluxes computed with different surface-flux computation schemes are compared with data from eddy covariance measurements in the surface air layer over lakes.

Ключевые слова: air - lake interaction, turbulent fluxes, thermal regime, modeling, eddy covariance measurements
