Winter so far dominated by intense Azores High

Winter 2022-23 [DJFDJF Meteorological Winter comprising the months of December, January & February] has been dominated to a large extent by a more intense Azores high than usual. This has kept things fairly mobile especially the north and has also provided a good deal of dry and quiet weather across southern parts, with increased numbers of overnight frost and fog. Anomalies have been generally between 4 and 8 hPahPa A Hectopascal is the SI unit of pressure and identical to the Millibar above the LTALTA Long Term Average. This is usually defined as a 30 year period by the WMO.. The only time the Azores high did relinquish its hold was in December of 2022, when the flow across 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. reversed and we saw the only spell of anticyclonic easterlies we’ve seen so far this winter.

Autumn 2022 [SON] – Days of Frost

Dear Diary,
The days of air frostair frost An air frost occurs when the temperature of the air falls below 0.0°C and ground frost were well down on their respective LTALTA Long Term Average. This is usually defined as a 30 year period by the WMO. for all regions, thanks to the very mild weather. I would have like to have added a colour contoured map but the Met OfficeUKMO The Meteorological Office is the United Kingdom's national weather service. It is an executive agency and trading fund of the Department for Business, Energy and Industrial Strategy don’t seem to generate them anymore for frost. Still plenty of sites still to report their first frost, some of them inland as well. My SYNOPSYNOP SYNOP (surface synoptic observations) is a numerical code (called FM-12 by WMO) used for reporting weather observations made by manned and automated weather stations. SYNOP reports are typically mad hourly and consist of groups of numbers (and slashes where data is not available) describing general weather information, such as the temperature, barometric pressure and visibility at a weather station. records are never guaranteed to be 100% complete, so I may have missed the odd one because either the value or the whole observation at 06 UTCUTC Coordinated Universal Time or UTC is the primary time standard by which the world regulates clocks and time. It is within about 1 second of mean solar time (such as UT1) at 0° longitude (at the IERS Reference Meridian as the currently used prime meridian) and is not adjusted for daylight saving time. It is effectively a successor to Greenwich Mean Time (GMT). was missing.

Autumn 2022 [SON] – Third warmest since 1659

Dear Diary,
Unsurprisingly, Autumn 2022 [SONSON Meteorological Autumn - September, October and November] ended up the third warmest since 1659 in Central England, with a mean temperature of 12.4°C, which was +2.4°C above the 1659-2020 LTALTA Long Term Average. This is usually defined as a 30 year period by the WMO.. There were only a few colder than average spells with warm spells dominating for long periods.

Some of the wetter places this Autumn

Here are some of the wettest places in the SYNOPSYNOP SYNOP (surface synoptic observations) is a numerical code (called FM-12 by WMO) used for reporting weather observations made by manned and automated weather stations. SYNOP reports are typically mad hourly and consist of groups of numbers (and slashes where data is not available) describing general weather information, such as the temperature, barometric pressure and visibility at a weather station. reports this meteorological Autumn so far. They may not have seen as much rainfall as the likes of Capel Curig or Tulloch Bridge, but their POAPOA Percentage Of Average put them in the top ten wettest places in the whole of 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.. Despite the local flooding in places, I reckon this wet Autumn has got to be looked upon as a good thing to replenish rivers and aquifers, but as you can see from the accumulations plotted in the map not all places have been as wet as these particular four sites. With a couple of weeks still left to go this could end up as one of the wettest Autumns on record.
