Accepted Answer

Geostationary satellites are equipped with water-vapor sensors that can profile the distribution of atmospheric water vapor in the middle and upper troposphere in order to help observe the movement of air in regions where there are no clouds. Special radiometers, ultraviolet imaging sensors, computer enhancement software, and reflected light imaging capabilities are not designed specifically for this purpose.

Question 14

When a cloud forms over and extends downwind of an isolated mountain peak,it is called a ____ cloud.
A)lenticular
B)banner
C)​cap
D)​pileus
E)​mammatus

Accepted Answer

Banner clouds form specifically in the lee of isolated mountain peaks, appearing to extend downwind from the peak, resembling a flag or banner. This phenomenon occurs when moist air flows over the mountain, cooling and condensing on the leeward side to form a cloud.
