Abstract. The paper describes simulating results of the phytoplankton vertical distribution in the aquatic ecosystems based on one-dimensional numerical model. The model is used to calculate the dynamics of the temperature, salt, limiting nutrient and phytoplankton biomass. The work shows some temporal variability of phytoplankton distribution in the surface layer of salt and freshwater lake ecosystems under the impact of hydrophysical processes. These results can be used for the satellite date interpretation.

Key words: numerical model, aquatic ecosystem, hydrophysical processes, phytoplankton, chlorophyll, biogenic element, rainfall, upwelling, turbulent diffusion, variability, inhomogeneity.
