Low Pressure Systems

Brings lousy weather.

- The air rises to create clouds, that will bring rain, storms, and low temperatures. The air rotates COUNTERCLOCKWISE.

High Pressure Systems

Brings happy weather. There is no moisture in the air to create clouds so the air just sinks. The air rotates CLOCKWISE.
