The panorama image shows the view from the tourist attraction Touchal,
located at an altitude of 3800 m, to the South over Teheran that
is approximately 15 km away. The (uppermost) inversion can be recognized
as a sharp line between the blue sky and the layer of air pollution
below. This inversion is located at an altitude of more than 3000
m. There are further inversions at lower altitudes. |
Therefore a brownish haze layer can be noticed at the bottom of
BLTop1.jpg to BLTop17.jpg. Boundary layer clouds of the kind of
Cumulus humilis which in this case are called boundary layer top
clouds are formed at the upper limit of the haze layer (i.e. at
the inversion). |
