The cold air over Scandinavia is squeezing it’s way eastward between low pressure over IONAIONAIslands 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. and high pressure over northern Sweden and Finland this lunchtime. Wind chill figures across the northeast are further reduced by heavy rain and strong to gale force southeasterly winds. The deeper colder air remains further east but there’s no denying that it’s icy fingers are forecast to permeate eastward in the next five days.

Weather patterns in Autumn may lead to flooding in February, Met Office warns. I’ve put a watch on this bit of news. I’ll revisit it at the start of March, if I remember and am still around, to see if the prediction holds water. The Guardian has made it impossible to directly share any of it’s articles with WordPress(?), so the only way around it was to share the article as a tweet and then embed the tweet in WordPress.
Spare a thought for those people working on the rigs in the North Sea tonight. The severe gale force southeasterly has whipped waves of 7 M in height in the last few days, with gusts well in excess of hurricane force 12 thrown in for good measure.
The 12 month rate of change in CO2CO2Carbon dioxide (chemical formula CO2) is a chemical compound made up of molecules that each have one carbon atom covalently double bonded to two oxygen atoms.

It’s the only way you can detect if something underlying is going on with CO2, because a plot of monthly values is relentlessly increasing by 24.8 ppm per decade, if you believe the simple linear trend.
According to the latest run of the GFSGFSThe Global Forecast System is a global numerical weather prediction system containing a global computer model and variational analysis run by the United States National Weather Service. model, The cold air to the east over the Baltic and Scandinavia is never very far away from the northeast of Scotland in the next five days.
We might think we’ve had a very mild November so far but it’s been exceptionally mild across southern Scandinavia with anomalies for the first two weeks +6.9°C above the 1991-2020 LTALTALong Term Average. This is usually defined as a 30 year period by the WMO.. The central Atlantic remains slightly colder than average despite the above average SSTSSTSea Surface Temperatures.
How’s this for a confusing bit of gobbledygook from the Met OfficeUKMOThe 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 about the 1.5°C rise in global temperatures. The title seems to suggest that 1.5°C will be realised in 2100 but that’s not what the article says. It may reach it before then and overshooting it, before falling back to +1.5°C by 2100. They seem to have side-stepped the $64,000 dollar question, which is of course when will global temperatures reach the much hyped 1.5°C higher than in pre-industrial times?
Another interesting satellite image this morning. After the rain stopped and the cloud cleared early yesterday evening here in the Strath, we promptly went into fog (sky discernable) which is only just thinning out now. A cold night with a minimum of just 1.4°C.

It is an executive agency and trading fund of the Department for Business, Energy and Industrial Strategy, but that didn’t prevent us getting the lawan cut and some leaves sucked up! Grass still growing in mid-November is something we can do without.
The year 2022 is still currently the warmest year in the CETCETCentral England Temperature series that started back in 1659. I make the mean temperature up to the 13th of November 12.08°C a massive +1.97°C above the 1961-1990 LTALTALong Term Average. This is usually defined as a 30 year period by the WMO.. It’s closest rival is the year 2014 with a mean of 11.72°C. I can’t see 2022 being beaten now, the only thing that might stop it is if we get a repeat performance of December 2010, which to be honest looks highly unlikely.
I can count at least twelve new daily maximums that have occurred this year (red diamonds), and another seven new daily high minimums as well. If you like me like snowy winters this graph does make pretty bleak viewing, with few in the way of air frosts.

It is an executive agency and trading fund of the Department for Business, Energy and Industrial Strategy. I’m sure we are going to hear a lot more about this particularly salient fact in the next few weeks, so I thought I would spend some time and write a viewer that displayed consecutive mean temperatures. I think I’ve come up with the best solution to visualise spells of above or below average climatic values, be they means of temperature, or totals of precipitation or sunshine.
It’s certainly true that there hasn’t been a longer, more incredible, spell of consecutive warm months in the gridded series since 1884, although there have been a couple of longer runs of consecutive cold months. The period between March 1885 and September 1886 saw 19 consecutive cold months for example. There are many ways of deriving statistics like this, using mean maximum or mean minimum, or perhaps changing the LTA.
Still a couple weeks left till the official end of the North Atlantic season, but it looks fairly certain that the 2022 has seen a slightly below average season using the ACEACEAccumulated cyclone energy (ACE) is a metric used by various agencies to express the energy released by a tropical cyclone during its lifetime. It is calculated by summing the square of a tropical cyclone's maximum sustained winds, measured every six hours. The resulting total can be divided by 10,000 to make it more manageable, or added to other totals in order to work out a total for a particular group of storms. as a measure. So many short lived tropical cyclones barely last more than 36 or 48 hours in recent years thanks to the intense forensic work of the NHC that counting the number of named storms (17) isn’t a particularly good way to measure just how active anyone season has been.
If you thought it was extremely mild across the north of Scotland take a look at southern Scandinavia. The solid returns of +6°C anomalies across the Lancashire plain are another indication that the Myerscough temperature was around 2°C too warm, but what do I know?

A truly extraordinarily mild day across the country today. Temperatures in the strath have already reached 18.6°C in this mornings sunshine, making it the warmest place in the British Isles, and even a touch warmer than along the Moray Coast. These high temperatures are being fueled by a super foehnFoehnA 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. effect that’s going on in the southwesterly flow in the broad and elongated warm sector, with winds over Ben Nevis and CairngormCairn GormCairn Gorm (Scottish Gaelic: An Cà rn Gorm) is a mountain in the Scottish Highlands. 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. close to hurricane force 12, and gusts in excess of 100 mph.
Ben Rich should have taken a look at the observations from mountain stations across Scotland, he might then have realised that you didn’t have to look at high level wind at 35,000 feet to find extremely windy conditions.
So a daytime maximum on Friday the 11 November 2022 of 18°C in the north of Scotland is termed Mild, whilst at the same time a maximum of 17°C in the southeast of England is termed Exceptionally Mild.
