  We consider an environmental interface regarding as a complex system, in
which difference equations for calculating the environmental interface
temperature and deeper soil layer temperature are represented by the coupled
maps. First equation has its background in the energy balance equation while
the second one in the prognostic equation for deeper soil layer temperature,
commonly used in land surface parameterization schemes. Nonlinear dynamical
consideration of this coupled system includes: (i) examination of period one
fixed point and (ii) bifurcation analysis. Focusing part of analysis is
calculation of the Lyapunov exponent for a specific range of values of system
parameters and discussion about domain of stability for this coupled system.
Finally, we calculate Kolmogorov complexity of time series generated from the
coupled system.
