Places where air pressure is high are called high pressure systems. A low pressure system has lower pressure at its center than the areas around it. Winds blow towards the low pressure, and the air rises in the atmosphere where they meet. On weather maps a low pressure system is labeled with red L.
Regarding this, how does wind move between high and low pressure areas?
As the air rises, the water vapor within it condenses forming clouds and often precipitation too. Because of Earth's spin and the Coriolis Effect, winds of a low pressure system swirl counterclockwise north of the equator and clockwise south of the equator. This is called cyclonic flow.
What is a low pressure area?
Thermal lows form due to localized heating caused by greater sunshine over deserts and other land masses. Since localized areas of warm air are less dense than their surroundings, this warmer air rises, which lowers atmospheric pressure near that portion of the Earth's surface.
