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. and the corresponding 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. for each of those weeks. It’s evident that the last anticyclonic spell occurred in the third week of September and since then the circulation has been mobile and usually from the W or SW.

It’s certainly been, and still is across the west of Wales, a very windy day with coastal gales and some strong gusts on the cold front, but nothing very exceptional for a late November day. There were gale or severe gale force winds and comparable gusts for several consecutive days last week in the Northern Isles without any warning at all. You know the Met Office are trying to justify their warning when they roll out gusts from non-standard exposure, cliff top sites like Berry Head and the NeedlesNeedles A non-standard WMO class 3 anemograph site, stuck on top of a near 300 foot limestone cliff, on the Isle of Wight. Old battery. What tickles me is the UKMOUKMO The Meteorological Office is the United Kingdom's national weather service.

It is part of the Cairngorms range and wider Grampian Mountains. With a summit elevation of 1,245 m (4,085 ft) above sea level, Cairn Gorm is classed as a Munro and is the seventh-highest mountain in the British Isles. but have no qualms at all using readings made atop a 300 foot chalk cliff.
As for today’s rainfall totals [06-18] nothing that excessive either, even if most of it was on the front itself. The warning mentioned 10 to 15 mm in 1 to 2 hours and 20 to 25 mm in a few places, both too excessive. There was just 0.2 mm here in the NENE North East of Scotland.
If the UKMO can take a hard line with the issuing of warnings in Scotland why can’t they do the same for everywhere else?
It seems we’re fast becoming a Nanny State even with regard to weather.

As Greavsie once said “It’s a funny old game Saint” and the same is true of weather as it is of football. We had to wait all Autumn till Sunday night before we saw our first air frostair frost An air frost occurs when the temperature of the air falls below 0.0°C, and now we’re looking at getting four frosts in a row here in StrathpefferStrathpeffer Strathpeffer (Scottish Gaelic: Srath Pheofhair) is a village and spa town in Easter Ross, Highland, Scotland, with a population of 1,469.. It’s just the luck of the draw with the timing of these frontal systems this week being early morning rather than in the early hours I suppose. Three cold days in the Highlands. The mean temperature in my AWSAWS Automatic Weather Station on Monday [00-00] was just -0.6°C. Temperatures never exceeded 5.2°C today and they are already falling as skies clear late this afternoon. Here’s hoping for a frost tonight anyway!

A rather surprising chart of temperature anomalies for North American for the first 20 days of November 2022. Well it was at least for me. The cold air and mountains of snow at Buffalo gave me the impression that the whole of November had been very cold but not so. For the first two weeks of November eastern America was extremely mild with anomalies as high as +8°C. The third week saw the opposite conditions and it was much colder, which reduced the magnitude of the warm high that you can see in the anomaly chart close to New York (+4°C). It’s just how climate is with extremes of temperature cancelling each other out within the space of a year or less.

Not quite as cold as 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 expected across large parts of central and eastern England overnight. If you’re not sure what the minimum temperatures will be over the highlands of Scotland, simply don’t add a temperature for Inverness, Braemar or Aviemore and then you can’t be wrong.

The overnight fog has been persistent across the Cromarty Firth and Straths and glens of Easter Ross this morning. In fact temperatures are still subzero after a moderate overnight frost. Here in StrathpefferStrathpeffer Strathpeffer (Scottish Gaelic: Srath Pheofhair) is a village and spa town in Easter Ross, Highland, Scotland, with a population of 1,469. temperatures fell to -3.5°C in the first frost of the Autumn. The fog looks to be around 300 feet thick or so and is blowing up the strath from the east. Higher up above the inversion at around 750 feet there’s a 5 to 10 knots wind blowing from the south. So as well as fog blowing up the strath from the east some is blowing up and over the ridge of the Cat’s back from the south. You can barely see what all the fuss is about in the lunchtime satellite image.

Undoubtedly the last couple of weeks in November have been very mild across Iceland, but don’t forget the cold weather back in October that brought the red warning for heavy snow from the IMOIMO Icelandic Meteorological Office (Icelandic: Veðurstofa Íslands) is Iceland's national weather service and as such a government agency under the Ministry of Environment and Natural Resources. It is also active in volcano monitoring, volcano seismology, and together with other institutions, responsible for civil protection in Iceland. This is climate in action, some weeks are warmer than average and some are colder. I reckon the 7 to 8 degrees are the result of foehnFoehn A foehn, is a type of dry, relatively warm, downslope wind that occurs in the lee (downwind side) of a mountain range. It is a rain shadow wind that results from the subsequent adiabatic warming of air that has dropped most of its moisture on windward slopes (see orographic lift). As a consequence of the different adiabatic lapse rates of moist and dry air, the air on the leeward slopes becomes warmer than equivalent elevations on the windward slopes. winds at stations in the north of the island like we saw in Snowdonia in the last week. I would like to have produced a thermograph with anomalies for Reykjavik but they don’t publish daily extremes so this will have to do a town on the south coast.

The town of Umm Said in Qatar lies around 60 km to the south of Doha the capital of Qatar where the 2022 World Cup is being held this year.
Umm Saʿīd, also called Musayʿīd or Mesaieed, town and port situated in Qatar, on the east coast of the Qatar Peninsula, in the Persian Gulf. It was established in 1949 as a tanker terminal by the Qatar Petroleum Company on an inhospitable, previously uninhabited site, along the sabkhah (salt flat) terrain characteristic of the coast.

This is a thermograph for the last 48 hours from Umm Said.
That weather in Qatar doesn’t look too severe at the moment for playing football, that’s if you can keep out of the sun which is easier said than done. Humidities are certainly higher because coming off the Persian Gulf but football beats coal mining and these are getting mighty well paid for running around kicking a ball for 90 minutes.
I hadn’t realised that the final wasn’t till the 18th of December – so we’ll never hear the end of it on TV for the next four week!!. As for the weather that looks set fair for the start of the completion.

With regard to global temperature the IPCCIPCC The Intergovernmental Panel on Climate Change is an intergovernmental body of the United Nations responsible for advancing knowledge on human-induced climate change. It was established in 1988 by the World Meteorological Organization and the United Nations Environment Programme, and later endorsed by United Nations General Assembly. uses the reference period 1850 to 1900 to represent pre-industrial temperature to measure the degree of global warming that has occurred. They say about this reference period in their 2018 report:-
In principle, ‘pre-industrial levels’ could refer to any period of time before the start of the industrial revolution. But the number of direct temperature measurements decreases as we go back in time. Defining a ‘pre-industrial’ reference period is, therefore, a compromise between the reliability of the temperature information and how representative it is of truly pre-industrial conditions. Some pre-industrial periods are cooler than others for purely natural reasons. This could be because of spontaneous climate variability or the response of the climate to natural perturbations, such as volcanic eruptions and variations in the sun’s activity. This IPCC Special Report on Global Warming of 1.5°C uses the reference period 1850–1900 to represent pre-industrial temperature. This is the earliest period with near-global observations and is the reference period used as an approximation of pre-industrial temperatures in the IPCC Fifth Assessment Report.
Global Warming of 1.5°C – IPCC Report
I thought I would look and see how the CETCET Central England Temperature series was doing and see if it was getting close to the magic +1.5°C. The daily mean maximum and minimum only began in 1878 so it’s not possible to calculate mean values using this data, but daily mean temperatures are available back to 1772, and so it’s possible to calculate a mean for 1850-1900. It’s also possible to go back further and calculate a mean from 1772-1900, or better still calculate a mean for the period 1772-1850, which in my opinion is a better start for the dawn of the industrial era or the industrial revolution.
The anomalies in the bar chart are larger than you would normally see because I’ve based them on a long-term average for the period 1851-2000. Annual mean anomalies nearly exceeded 1.5°C back n 1949, and in recent years the 1.5°C barrier has been breached at least six times including this year (2022) which looks likely to become the warmest year on record. So we’ve not quite reached the +1.5°C mark globally but we are not far off in central England. I wonder what Gordon Manley would make of it all?
What caused the cooling between 1950 and 1980 in global as well as temperatures in central England? Maybe it was the airborne testing of thermonuclear weapons that followed the second world war and which continued till around 1976 according to Wikipedia. Natural variability or man made? My money’s on the latter in this case.

So far Autumn 2022 has been relatively frost free 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..

I make the wettest place in Aberdeenshire, using estimates from weather radar, the bridge of Dee with 143.6 mm of rain since the start of Wednesday (16 November) till now. That’s the wettest residential site but there are some deep purple pixles and a couple of white ones indication totals above 225 mm. Here’s a league table of wettest residential places, and as you can see there are other sites outwith Aberdeenshire.
It looks like the rain that continues to fall across Aberdeenshire has slackened off in regards to intensity and is now more of an orographic nature than frontal.

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.
