Previously:27–28 December 2016, MeteoLux recorded the highest atmospheric pressures observed at the Luxembourg Findel Airport weather station since measurement began in 1947, a value of 1047.2 hPa was recorded twice (under the high pressure Yörn. The previous record to this was from February 15–16, 1959 at 1046.6 hPa.
The highest adjusted-to-sea-level barometric pressure ever recorded (below 750 meters) was at Agata, Evenkiyskiy, Russia, elevation: 261 m (856.3 ft)) on 31 December 1968 of 1083.3 hectopascals (hPa) (31.99
The Azores High also known as North Atlantic (Subtropical) High/Anticyclone or the Bermuda-Azores High, is a large subtropical semi-permanent centre of high atmospheric pressure typically found south of the Azores in the Atlantic Ocean, at the Horse latitudes. It forms one pole of the North Atlantic oscillation, the other being the Icelandic Low.
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 .

In meteorology, the polar highs are areas of high atmospheric pressure, sometimes similar to anticyclones, around the North and South Poles; the south polar high (Antarctic high) being the stronger one [1] because land gains and loses heat more effectively than sea, which the north has much less of.
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).

However, during the winter of 2010–11 in Northern and Western Europe, the Icelandic Low, typically positioned west of Iceland and east of Greenland, appeared regularly to the east of Iceland and so allowed exceptionally cold air into Europe from the Arctic. A strong area of high pressure was initially situated over Greenland, reversing the ...
