| Zusammenfassung |
| Climate is usually considered to depend on a large number of parameters, this
being essentially a functional in multi-dimensional parameter space. We
propose a low-dimensional model of a climate where the temperature field on a
thermally conducting planet depends on the external energy input and very
limited number of internal parameters, like thermal conductivity and
reflectivity. Equilibrium temperature and quasistatic variations of climate
following slow variations of the energy input are studied. The single phase
model exhibits adiabatic behavior and stability with respect to small
axisymmetric perturbation. The two phase model shows a non-trivial response
to the variations of the external parameter. History dependence, global
instabilities and hysteresis behavior characterize the surface temperature
evolution. |
