| Abstract: | In this paper, considering stochastic forcing action in land-air system, the second order stochastic fluctuation climate model of land-air interaction is derived by using the thermodynamic equilibrium equation. It is found that there are two kinds of quasi-periodic oscillations in subsurface temperature departure, one is the oscillation of quasi-six months ranging from four to nine-months; the other, from two to three-years, and that there is a minimum period with the changes of some climate parameters. It is also found that the relative importance of both the interaction and self-feedback action in , land-air system for above-mentioned two periodic oscillations is different. |
