Hot Air Rises Air can hold less water at higher altitudes 1. Hot air rises over land due to heating by the sun. 2. The rising air leaves less air in one spot, low pressure forms. 3. Generally, from 3,000 to 5,000 feet, the air cools, high pressure develops. 4. Meanwhile, over the cooler water, air sinks, leaving less air aloft. 5. More air piles up at the surface of the water, high pressure forms. 6. Air moves from high pressure to low pressure. 7. The sea breeze generally forms during the afternoon. This creates a mini cold front that helps lift air upward to create thunderstorms.
