Expert Answer
Low pressure area:
A low pressure area is created when the air pressure in that area drops below the regular atmospheric pressure.
Air flows into this area.
When air flows into the area it has no place to go, so it rises up. As it rises, it cools down and forms clouds leading to stormy weather.
High pressure area:
A high pressure area is created when the air pressure in that area rises above the regular atmospheric pressure.
Air flows out of this area.
When air flows out of this area, new air from above has to take its place. As air descends, it heats up leading to slightly hot weather.
