Earth air pressure mbar
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. Atmospheric pressure, also known as barometric pressure (after the barometer), is the pressure within the atmosphere of Earth. The standard atmosphere (symbol: atm) is a unit of pressure defined as 101,325 Pa (1,013.25 hPa), which is equivalent to 1013.25 millibars, 760 mm Hg, 29.9212 inches Hg, or 14.696 psi. … See more Atmospheric pressure is caused by the gravitational attraction of the planet on the atmospheric gases above the surface and is a function of the mass of the planet, the radius of the surface, and the amount and composition of the … See more Surface pressure is the atmospheric pressure at a location on Earth's surface (terrain and oceans). It is directly proportional to the mass of air over that location. For numerical reasons, atmospheric models such as See more The highest adjusted-to-sea level barometric pressure ever recorded on Earth (above 750 meters) was 1084.8 hPa (32.03 inHg) … See more One atmosphere (101.325 kPa or 14.7 psi) is also the pressure caused by the weight of a column of freshwater of approximately 10.3 m (33.8 ft). Thus, a diver 10.3 m underwater … See more The mean sea-level pressure (MSLP) is the atmospheric pressure at mean sea level (PMSL). This is the atmospheric pressure normally … See more Pressure on Earth varies with the altitude of the surface, so air pressure on mountains is usually lower than air pressure at sea … See more Atmospheric pressure varies widely on Earth, and these changes are important in studying weather and climate. Atmospheric pressure shows a diurnal or semidiurnal (twice-daily) cycle caused by global atmospheric tides. This effect is strongest in tropical zones, … See more

WebDec 3, 2013 · Pressure is usually around 1000hPa, and at sea level, it rarely gets lower than 950hPa or higher than 1050 hPa. So high pressure gives fine, dry weather – warm in summer (remember how glorious July was!) but with cold nights in winter. But on the other hand, low pressure brings clouds, rain and strong winds. The first barometers used a J ... WebAir Pressure: Air Pressure at Altitude Fomula: p = p0e- (h/h0) Where: p: Atmospheric pressure, in Pa. p0: Atmospheric Pressure at Sea Level, in Pa. h: Height (Altitude), in meter. h0: Scale Height, in meter. Note: The surface pressure on Earth is approximately 1 bar, and the scale height of the atmosphere is approximately 7 kilometers.
WebPlease enter the altitude in meters or the air pressure in hectopascals (= millibars). The other value will be calculated. The international altitude formula used for the calculation is: air pressure = 1013.25 hPa * [ 1 − 6.5 * altitude / (288150 m) ] 5.255 Example: on top of the mountain Zugspitze, at an altitude of 2962 meters, the average air pressure is just over … Webatmospheric pressure unit. millibar, unit of air pressure in the metric system, commonly used in meteorology, equal to 100 pascals, 1,000 dynes per square cm (about 0.0145 pounds per square inch), or slightly less than one-thousandth of a standard atmosphere. This article was most recently revised and updated by John P. Rafferty.
