Indicates a low-pressure center, which is a region of relatively 

lower pressure. Moving away from a low-pressure center results 

in increased pressure. Winds flow counterclockwise around low-

pressure centers in the northern hemispheres.

higher pressure. Moving away from a high-pressure center 

results in decreased pressure. Winds flow clockwise around 

high-pressure centers in the northern hemispheres.
