Warm air is increasing to create low pressure zone; cool air is falling, creating a high pressure region. Air pressure and climate are rising warm air. Winds cause weather that moves across high-and low-pressure areas horizontally. The faster the wind moves, the higher the pressure difference between the pressure zones.
