Interactive atmospheric pressure map. ICON and GFS models. Shows global forecasted mean sea-level pressure.
Air pressure above sea level can be calculated as. p = 101325 (1 - 2.25577 10-5 h)5.25588 (1) where. 101325 = normal temperature and pressure at sea level (Pa) p = air pressure (Pa) h = altitude above sea level (m) Example - Air pressure at Elevation 10000 m. The air pressure at altitude 10000 m can be calculated as.
Atmospheric pressure, also known as air pressure or 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 1,013.25 millibars, [1] 760 mm Hg, 29.9212 inches Hg, or 14.696 psi. [2]
This web app graphs the barometric pressure forecast and history of any location, along with relevant current weather data such as temperature, humidity and wind.
Mean Sea Level Pressure charts with fronts, air pressure centers, weather symbols. In addition: The access to further medium-range multiple forecast charts (height / temperature 500 hPa, Mean Sea Level Pressure) from the European and the American model is offered in the right column. Here the link to the official ECMWF page.
Map of global mean air pressure at sea level in July, where high-pressure centers are more pronounced, especially over the North Atlantic and North Pacific oceans. Near Earth’s surface, atmospheric pressure decreases with height at a rate of about 3.5 millibars for every 30 meters (100 feet).
24 maj 2024 · A constant height map (also known as a "constant height chart") shows the distribution of pressure at sea level. Isobars, lines connecting points of equal air pressure are used to show pressure patterns on constant height maps.
