High pressure

High pressure is like being squished by someone or something really hard. Just like when you squeeze a balloon, it gets harder and harder until it pops. In the atmosphere, high pressure means that there is a lot of air pushing down on the earth's surface, like a heavy weight. This can happen when there is a lot of cool air in one place that sinks down and presses on the ground. High pressure weather is usually associated with clear skies and nice weather, but it can also cause dryness, drought, and heat waves. So think of high pressure like a big hug that's squeezing you - it can feel really nice, but it can also be too much sometimes!
