Generation of Available Potential Energy due to the Long-wave Radiation Influx in the Atmosphere

N. A. Kalinin and I. L. Lukin

Investigated are the features of the distribution of the generation of available potential en¬ergy (APE) due to the influx of long-wave radiation in the atmosphere. The reanalysis (ERA-Interim) data of the European Center for Medium-Range Weather Forecast are used as the reference values of fields for computing APE generation. The obtained results indicate the influence of cloudiness and at¬mospheric stratification on APE generation due to the inflow of long-wave radiation which values are by 4–5 times smaller than the values of APE generation due to the phase transitions of moisture in the atmosphere.
