What is a high pressure system?

Back

A high pressure system is an area where the atmospheric pressure is higher than the surrounding areas, usually bringing clear skies and calm weather.

Front

What is a low pressure system?

Back

A low pressure system is an area where the atmospheric pressure is lower than the surrounding areas, often leading to cloudy skies and precipitation.

Front

What happens when a cold front passes?

Back

When a cold front passes, it typically brings cooler temperatures and can cause thunderstorms.

Front

What happens when a warm front passes?

Back

How does temperature affect air pressure?

Back

Warm air is lighter and rises, leading to lower pressure, while cold air is denser and sinks, leading to higher pressure.

What is the significance of isobars on a weather map?

Back

Isobars are lines that connect points of equal atmospheric pressure; they help indicate wind speed and direction.
