WebOct 22, 2016 · Higher pressure is lower altitude. So the smaller the mb, the higher we are in feet. 1000 mb is about sea level. The international standard is 1013.2, but "about 1000" is easier to remember. 300 mb is about 30,000 feet. An easy one to remember, most contrails in temperate areas like the US (excepting Alaska) happen above 30,000 feet, so ... WebAt the Earth’s surface the air pressure of the atmosphere is usually within the range 980 to 1030 hPa. The hectoPascal is the modern replacement unit for the millibar: one hPa = one millibar = one thousandth of a “bar”. The millibar was introduced by the British meteorologist Sir Napier Shaw in the early 1900s.
WebApr 24, 2024 · Air pressure is also known as barometric pressure, which is measured by barometers. Air pressure is lower at high altitudes, where there is less air pushing down. Air pressure is highest at sea level. Air … WebTo place this sea-level pressure in perspective, check out the barograph showing the range of sea-level pressures again.
