Met Office daily weather report supplementary chart of barometer over Europe on 24 January 1907, for 8 am 23 January with a high of 31.5 inches of mercury (1,070 hPa) over Latvia. Land-based records for Europe: Highest observed air pressure record:
Most intense ever recorded on land: 892 hPa (26.35 inHg); Craig Key, Florida, United States, eye of the Labor Day Hurricane, 2 September 1935. While other landfalling tropical cyclones potentially had lower pressures, data is vague from areas other than the Atlantic basin , especially before the invention of weather satellites .
The timeline of meteorology contains events of scientific and technological advancements in the area of atmospheric sciences. The most notable advancements in observational meteorology , weather forecasting , climatology , atmospheric chemistry , and atmospheric physics are listed chronologically.
The global models are run at varying times into the future. The Met Office's Unified Model is run six days into the future, [55] the European Centre for Medium-Range Weather Forecasts model is run out to 10 days into the future, [56] while the Global Forecast System model run by the Environmental Modeling Center is run 16 days into the future.

On weather maps, these areas show converging winds , also known as convergence, near or above the level of non-divergence, which is near the 500 hPa pressure surface about midway up through the troposphere, and about half the atmospheric pressure at the surface. [8] [9] High pressure systems are also called anticyclones.
After reaching a peak intensity with winds of 40 mph (65 km/h) and a barometric pressure of 1003 mbar (hPa; 29.62 inHg), the storm began to weaken again due to increasing wind shear and the unusually fast movement of Ana. In post-storm analysis, it was discovered that Ana had degenerated into a tropical wave once more on August 16, before ...
A wind gust of 194 mph (312 km/h) was recorded at Cairn Gorm on 19 December 2008 but was discovered too late to be verified by the Met Office. [ 14 ] The highest wind speed in England was a wind gust of 125.4 mph recorded at The Needles , Isle of Wight , on 18 February 2022 during Storm Eunice .
The UK Met Office released their forecast on May 21, predicting 13 named storms, 7 hurricanes, 3 major hurricanes, and an accumulated cyclone energy of 109 units. [10] On May 23, NOAA released their first prediction, calling for a near-normal season with 9–15 named systems, 4–8 hurricanes, and 2–4 major hurricanes. [ 11 ]
