The lowest confirmed barometric pressure reading, 955.0 mb (28.20 inHg), for a non-tropical system in the continental United States (CONUS) was recorded during this storm at Canton, New York. [2] [3] This broke the record low of this type set by the January 1886 Blizzard. The lowest pressure reading of this type was later equalled on March 7 ...
The 20th Century low pressure record onshore in the UK occurred on 20 December 1982 at Sule Skerry dropping as low as 936 hPa. 937.6 hPa was recorded at Stornoway on 20 December 1982 as the lowest barometric pressure observed anywhere in the British Isles since 1886. 931 [88] 1983, 5 January South of Iceland,
Christopher C. Burt, a weather historian writing for Weather Underground, believes that the 1913 Death Valley reading is "a myth", and is at least 2.2 or 2.8 °C (4 or 5 °F) too high. [13] Burt proposes that the highest reliably recorded temperature on Earth could still be at Death Valley, but is instead 54.0 °C (129.2 °F) recorded on 30 ...
A low pressure area detached from a stationary front and developed into a tropical depression on August 14 while located about 185 mi (298 km) west-southwest of Bermuda. [3] [4] The depression moved rapidly northeastward and intensified into a tropical storm on August 15. Thereafter, it peaked with maximum sustained winds of 45 mph (72 km/h). [4]
1667 – Robert Hooke builds another type of anemometer, called a pressure-plate anemometer. [22] 1686 – Edmund Halley presents a systematic study of the trade winds and monsoons and identifies solar heating as the cause of atmospheric motions. – Edmund Halley establishes the relationship between barometric pressure and height above sea ...
Barometric pressures in some areas began to rise, bringing hopes of an end to the storm. The low pressure area that had moved across Lake Superior was moving northeast, away from the lakes. [26] The Weather Bureau issued the first of its twice-daily reports at approximately 8:00 a.m.; it did not send another report to Washington, D.C., until 8: ...
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 .

South of the front warmer and moister air was present, but dewpoints in the upper 50s were confined to southern Oklahoma and Arkansas, far away from where the tornadoes were to later occur in eastern Nebraska and western Iowa. As the day progressed, the surface low ejected through Nebraska, with a dry line and trailing cold front. South winds ...
