With low pressure, air rises, cools, and condenses into storm clouds, which may lead to a rainy day. Since the rising column of air weighs less, the air pressure is lower.

The sinking air can create areas of high pressure at the Earth’s surface. When high pressure is in control, the air sinks. Sinking air compresses the atmosphere and inhibits clouds to form.

We just used sea breeze as an example to describe how pressure changes create wind. Let’s demonstrate how the air flows from high to low pressure in the fun experiment below!

Your optimal continuous positive airway pressure (CPAP) setting is the lowest amount of air pressure able to keep your airway unobstructed and prevent things like snoring or breathing pauses while you ...

Background Mechanical thrombectomy with stent retriever devices is associated with significantly better outcomes than thrombolysis alone in the treatment of acute ischemic stroke. Thrombus aspiration ...

The biggest way to improve air quality is to reduce emissions. You can work out where the emissions come from by looking at an emission inventory (see lesson 8 for more about this). Emissions ...
