摘要: The application of methods modern theory Brownian motion to the calculation fluctua� tions soil moisture reserve is considered. Analytical dependences correlation time fluctuations and its mean on characteristics external stochastic deterministic impacts are obtained for a nonlinear hydrological model formation based Langevin equation generalized relationships. Variations lowfrequency part spectrum fast synoptic vari� ables (the difference between precipitation evaporation) because interaction with examined. A new effect—an increase in intermediate domain intervals characteristic times—is explained by variations reserve. problem determining nonsteady response fluctuation moistening regime used demonstrate potentialities apparatus statistical physics—fluctuation theorems.
