an area where the measured pressure is lowest relative to
the surrounding area. Moving away from a low-pressure
center in any horizontal direction results in increased
pressure. Winds flow counterclockwise around low-
pressure centers in North America.

an area where the measured pressure is highest relative to
the surrounding area. Moving away from a high-pressure
center in any horizontal direction results in decreased
pressure. Winds flow clockwise around high-pressure
centers in North America.
