Abstract
Results are reported from experimental and theoretical studies of the energy and mass exchange of a body of water with the atmosphere. A new parametric model has been developed on the basis of experimental data that takes into account the influence of the depth of the basin on evaporation, its heat exchange with the atmosphere, and the water-surface friction at different wind speeds. Comparison of the model with measurements during the LITFASS-98 and LITFASS-2003 experiments (Germany) shows good consistency. The results indicate, on the one hand, that the depth of the basin has a large effect on the intensity of energy exchange under natural conditions. On the other hand, the examples shown in the paper illustrate good agreement of the model calculations with experimental data. On the basis of the experimental data on the influence of the basin depth on the intensity of the interaction between the basin and the atmosphere, a balance model of the energy exchange in the coastal zone has been developed. The balance model calculates the momentum, heat, and moisture fluxes at different distances from the shore. Results of using the new model to estimate the intensification of evaporation and the heat exchange of the northern Caspian and the Kara-Bogaz Gol are discussed.
