Pressure altitude is used to determine your aircraft’s performance in non-standard conditions, which are any time the barometric pressure is anything other than 29.92 Hg at sea level.

Atmospheric pressure Whenever rain or bad weather moves into a region, it’s often associated with the appearance of a system of low atmospheric pressure. But what exactly is atmospheric pressure?

As barometric pressure falls, tissues around joints can expand or swell, leading to pain, especially for those with arthritis. If colder temperatures accompany the pressure drop, that can lead to ...

At sea level, the average pressure is 1.013 bars. We use the sea level pressure standard to determine if air pressure will be relatively high or low as weather systems move over us.

Atmospheric pressure changes could be driving Mars' elusive methane pulses Simulations will help Curiosity search for signs of past or present life on the Red Planet Date: January 24, 2024 Source ...

In low pressure systems, the rising air can carry water vapor into the colder reaches of the atmosphere, where it can condense and turn into rain. But the high pressure system affecting Texas is ...

Temperatures may reach 70 degrees early next week. A weather system connected to an atmospheric river will start impacting Northern California late Wednesday.
