Standard sea-level conditions (SSL), [1] also known as sea-level standard (SLS), defines a set of atmospheric conditions for physical calculations.The term "standard sea level" is used to indicate that values of properties are to be taken to be the same as those standard at sea level, and is done to define values for use in general calculations.
Typhoon Megi (pronounced), known in the Philippines as Super Typhoon Juan, was the ... and a mean sea level pressure of 890 hPa (26.28 inHg) at 13:05 UTC. ...
The state weather agency of the Philippines said Mawar has “slightly intensified” while moving westwards over the Philippines sea”. ... (~195 km/h), and a pressure of 920 hPa.
After passing Guam, Tip rapidly intensified and reached peak sustained winds of 305 km/h (190 mph) [nb 1] and a worldwide record-low sea-level pressure of 870 hPa (25.69 inHg) on October 12. At its peak intensity, Tip was the largest tropical cyclone on record, with a wind diameter of 2,220 km (1,380 mi).
On October 29, both the highest wind gust of 130 km/h (81 mph) at 21:25 UTC and lowest sea-level pressure of 971.8 hPa (28.70 inHg) at 21:00 UTC were recorded at Casiguran, Aurora. Between 50 and 200 mm (2.0 and 7.9 in) of rain was estimated to have fallen over Northern Luzon, while 200 and 300 mm (7.9 and 11.8 in) of rain was estimated ...
The deepest point of the trench is more than 2 km (1.2 mi) farther from sea level than the peak of Mount Everest. [a] At the bottom of the trench, the water column above exerts a pressure of 1,086 bar (15,750 psi), more than 1,071 times the standard atmospheric pressure at sea level. At this pressure, the density of water is increased by 4.96%.
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.

Map of pressure systems across North America. A pressure system is a peak or lull in the sea level pressure distribution, a feature of synoptic-scale weather.The surface pressure at sea level varies minimally, with the lowest value measured 87 kilopascals (26 inHg) and the highest recorded 108.57 kilopascals (32.06 inHg).
