Altitude decreases with air molecules in the upper layers compressing the layers below them is what makes barometric pressure high.
A barometric pressure reading over 30.20 inHg is generally considered high, and high pressure is associated with clear skies and calm weather
Correct and normal barometric pressure is in the 29.9; range ~29.6 - 30.2 inches Hg (752-767 mm Hg)… at SEA LEVEL!
Any barometric reading in the range of 29.80 and 30.20 inHg can be considered normal, and normal pressure is associated with steady weather.
If the barometric reading falls between 29.80 and 30.20 inHg (100914.4–102268.9 Pa or 1022.689–1009.144 mb): Rising or steady pressure means present conditions will continue.
Adjusted to sea level, a barometric pressure reading that is above 30.2 inHg is considered to be high pressure, and below 29.8 inHg is considered low.
Most of the time, in human-inhabited places, the barometric pressure will stay close to the normal range (29.8 inHg-30.2 inHg), and will rarely exceed 30.5 inHg or fall below 29.4 inHg.
The barometric pressure also known as atmospheric pressure is the pressure within the atmosphere of Earth.
The standard atmosphere is a unit of pressure defined as 101,325 Pa, which is equivalent to 1,013.25 millibars, 760 mm Hg, 29.9212 inches Hg, or 14.696 psi.
Barometric pressure often drops before bad weather.
Lower air pressure pushes less against the body, allowing tissues to expand.
Expanded tissues can put pressure on joints and cause pain.
When the barometric pressure drops, it can also cause a decrease in oxygen and blood flow to the brain, leading to headaches.
Low barometric pressure can cause fatigue and lethargy, particularly in people who are sensitive to changes in pressure. T
his is because low pressure can cause a decrease in oxygen levels in the body.
The ideal barometric pressure typically falls between 29 and 31 inHg.
This barometric pressure is comfortable for most people and will possibly allow them to live with less joint pain, especially if the area they reside in does not fluctuate rapidly throughout the day or week with barometric pressure readings.
