Abstract
The article deals with calculations of the long term quasiperiodic variations of the solar constant influence on the excessive or deficit amount of thermal energy during the warming and cooling periods. Preliminary analyses of the influence of the factor in question on the climate of the Earth is carried out. The lack of equilibrium of planetary temperature due to both bicentennial and eleven-year cycles of the solar luminosity results in synchronic variations of the solar constant. The method of computing the changes of energy imbalance of the Earth between the planetary absorbed and outgoing energy fluxes under the influence of long-term periodical variations of the TSI is developed. The formula for the increment of the integrated heat energy over the time during the half-period of bicentennial variation of the TSI is obtained. Calculations are provided for a bicentennial period but the described method makes it possible to take in account a combination of bicentennial and eleven-year cycles.

Keywords: energy balance, periodical variations, solar constant, planetary temperature, thermal inertia, specific capacity of heat emission.
