MOISTURE, SENSIBLE HEAT AND KINETIC ENERGY BUDGETS DURING THE HEAVY RAINFALL

In this paper the kinetic energy, sensible and latent heat budgets over limited area are calculated during the heavy rainfall in July 1977.In the heavy rainfall system sensible and latent heat, supplied from surroundings, are converted into kinetic energy, which is transported out of the area at upper levels by horizontal flux divergence. Subgrid-scale motion leads to increase of sensible heat and decrease of latent heat of the grid scales of motion.Transfer of kinetic energy from subgrid to grid scales of motion is observed in the area with most intense rainfall, but an opposite transfer occurs in its surroundings. Some results of this paper are useful for designing numerical models of precipitation.
