Low Pressure Wind Model
Air around a LOW pressure rises in a counter-clockwise rotation, moving in toward the center of the LOW. The winds around a LOW pressure always move in a counter-clockwise rotation in the Northern Hemisphere. As the air rises it expands, cools, and condenses into clouds.

High Pressure Wind Model
Air around a HIGH pressure FALLS in a clockwise rotation, moving away from the center of the HIGH. The winds around a HIGH pressure always move in a clockwise rotation in the Northern Hemisphere. As the air Falls it compresses, warms, and water vapor evaporates. Clouds disappear!
