4.a.ii. Horizontal mean temperature and potential temperature
Figure 11c and
Figure 11d show the time development
of vertical profiles of horizontal mean temperature and
potential temperature during the daytime
of the first day and the second day
of the dusty case.
The results of the first day are similar to those of the
dust-free case
(Figure 3a).
In the second day,
horizontal mean potential temperature from 10 to 15 km
height becomes vertically uniform after LT=13:00.
This indicates that there exists vertical mixing
in the levels from 10 to 15km height.
Vertical mixing is caused by the
vertical contrast of solar heating associated
with dust
(see also Figure 11h).

from LT = 8:00 to 18:00 on the first day of the dusty
case.
