Normal sea-level pressure has a value of:
1013.2 mb or 760 mm of mercury.
Which of the following statements best describes the friction force?
It decreases with height above the surface.
The combined effect of the Coriolis force and the pressure gradient force in the upper atmosphere produces:

Geostrophic winds.
Between 20° and 35° north and 20° and 35° south latitudes, you find:
Arid and semiarid desert regions.
The east side of subtropical high-pressure cells (off continental west coasts) tend to be:

Dry, stable, and warm
Land-sea breezes are caused by:

Onshore (toward the land) airflows which develop in the afternoon as the land heats faster than the water surfaces.
Monsoonal winds are:

Regional wind systems that change direction seasonally.
Which of the following statements is true?
Three-fourths of the atmosphere occurs below 10,700 m (35, 105 ft).
The pressure gradient force:
Initiates air flow and causes winds.

Straight across isobars.
From which direction do the prevailing winds come in the midlatitudes?

West.
In the Northern Hemisphere from which direction do the trade winds come?
The north-east.
Which of the following accurately describes air flow in a Northern Hemisphere low pressure cell?
