Based on the results of our numerical simulations presented so far,
we now discuss the following issues.
Since the observation of wind and temperature
by the Viking lander was performed at the height of 1.6 m,
it may be informative to compare them with the data
obtained at the lowest level of our
numerical model (about 1.5 m height).
Our numerical simulations show that surface wind associated
with the km-size thermal convection
of the dust-free case can raise dust from the surface.
We can suggest that,
it is necessary to incorporate
the effect of the km-size thermal convection
into a Martian GCM
to improve it to be more like that of the Mars,
i.e., with the emergences of dust storms.
