MSLPMSLP Mean sea level pressure is the pressure at sea level, or, when measured at a given elevation on land, the station pressure reduced to sea level assuming an isothermal layer at the station temperature. & 500 hPahPa A Hectopascal is the SI unit of pressure and identical to the Millibar gph
I can already see a few similarities in the first week of September with the memorable September of 1959. September 1959 had the third longest anticyclonic spell in the whole objective LWTLWT Lamb Weather Types are often used in UK-based analyses, with individual weather patterns based on the eight primary cardinal directions (N, NE, E, SE, S, SW, W, NW) plus cyclonic (C), anticyclonic (A) and unclassified (U) types. series that began in 1871. The heatwave in the first week of September 2023 looks poised to break a number of CETCET Central England Temperature record maximum temperatures that were set in 1959. In 1959 as well as possible heatwave conditions occurring between the 7th and 12th of September in central England, a second warm spell occurred between the 3rd and 7th of October. It will be interesting to see just how anticyclonic September 2023 proves to be, and if November turns out to be as cyclonic as that of 1959.
