Pishniak D. Thermodynamic and energy conditions of mesoscale processes in frontal zones of the atmosphere

The object - mesoscale structure of atmospheric fronts; the aim - establishment thermodynamic laws of frontal zones and frontal mesoscale disturbances development, creating new quantitative energy parameters for diagnosis and prediction mesoscale properties of atmospheric fronts; methods - numerical modeling, computational post-processing of simulation, physical analysis, spatial and temporal generalization; the results - implemented a numerical scheme for energy conversion evaluation in the atmosphere, based on the semi-Lagrangian advection; developed a method for calculating the spatial distribution available potential energy, important for processes of various sizes, as well as the integral parameter FAPE based on it; established general and individual regularities of mesoscale processes; the novelty - is in developed method for diagnosing the atmospheric processes energy and conclusions about their behavior in the mesoscale of frontal zones, obtained from high spatial and temporal resolution; the introduction degree - is introduced; the branch of using - forecast centers, scientific and education organizations.
