Integration of the dust-free case is carried out for
six days from the initial condition.
Regular diurnal variations can be recognized
in the time series of total energy and kinetic energy
by day 6.
The model atmosphere can be regarded as in
an energetically equilibrium state on the time scale of
diurnal change by this date.
Hereafter, we are going to show the results obtained
in the sixth day of the simulation.
