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 ...
Peaking with maximum sustained winds of 75 mph (121 km/h) and a minimum barometric pressure of 989 mbar (29.2 inHg), the hurricane made landfall near McClellanville, South Carolina, about eight hours later. By the evening of October 8, the cyclone weakened to a tropical storm and fell to tropical depression intensity by late on October 9.
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 ...
The central pressure rapidly dropped 54 millibars (1.6 inHg) from 0000 to 0600 UTC, and at 0800 UTC, a hurricane hunters flight recorded a minimum central pressure of 884 millibars (26.1 inHg) in a dropsonde near the center of the extremely small eye. As the dropsonde did not reach the calm winds in the center, the pressure was estimated at 882 ...
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 ...
The first low-pressure system from the storm weakens and moves northeast from the Great Lakes into eastern Canada and New England. [27] [28] The system stalls over the Ohio River basin and triggers more rain and thunderstorms. [27] [28] A second low-pressure system that developed in Colorado merges with a third low that forms over western Texas ...
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 .
