The Coriolis effect is strongest at the equator and diminishes in strength poleward.
The pressure gradient force is the driving force behind wind.
A southwest wind blows toward the northeast.
An isobar is a line connecting places of equal humidity.
Anticyclones characteristically have winds blowing out from their centers.
The ultimate cause of a sea breeze is the unequal heating of land and water.
Horizontal movement of air is called wind.
A mountain breeze is best developed in the hottest part of the day.
The region where the trade winds meet is also called the DOLDRUMS
Most of the people living in the United States are under the influence of the wind belt known as the westerlies.
Closely spaced isobars indicate high wind speeds.
In the Northern Hemisphere, winds blow clockwise and outward from the center of anticyclones.
