Don’t get the idea that the positive 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. anomalies across the SW of England of +13.8 hPahPa A Hectopascal is the SI unit of pressure and identical to the Millibar so far this February are in anyway exceptional – on looking at all February’s back to 1948 using reanalysis data, I think I can safely say it’s not. Put it down to my naivety, I never realised just how varied the month of February, or any month for that matter, can be in IONAIONA Islands Of North Atlantic. Yes I know there's an island called Iona, but this is so I don't have to use the term 'British Isles' when referring to the whole of Ireland and the UK.. Take a look at the very anticyclonic nature and anomalies of Februaries in 1959 and 2012 are for example, or the anomalies and AEAE Anticyclonic Easterly of 1986, but there I’m straying off topic.
