Highland temperatures

Dear Diary
I don’t know how we managed to avoid a frost last night but we did with a minimum of 0.3°C at 0017 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).. After that I imagine the cloud must have increased because the wind remained very light from the W’SW. The unusual thing is that although you would expect the minima to occur at around sunrise (0831 this morning) it didn’t. Instead the overnight cloud quickly dispersed and we were left with blue skies, but temperatures continued to fall back from 3.9°C at 0700 UTC to just 1.2°C at 1100 UTC. This is because as the name suggests StrathpefferStrathpeffer Strathpeffer (Scottish Gaelic: Srath Pheofhair) is a village and spa town in Easter Ross, Highland, Scotland, with a population of 1,469. is in a strath and from about the end of November the sun never gets over the Cats Back (a long ridge to the south of the village). The sun eventually struggle over the ridge but it takes till mid morning to do it. The Highlands are full of glens and straths like this, many of them won’t see direct sunshine again until the end of February.

No Beast from the East

Dear Diary,
The UKMOUKMO 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 are trying their very hardest to dissuade people from thinking that they’re not looking down the jaws of another Beast from the East in the coming few days, temperatures they say will only fall slightly below the seasonal average. It might come as news to them that temperatures have today been lower than the 5°C they promise for this coming Saturday. Today the minimum in the dip 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., and despite a mainly sunny day, was just 3.9°C so it’s already cold. It may well warm up of course once the easterly gets going and maybe brings some milder air up off the Cromarty Firth.

They’re in trouble when Berry Head and the Needles are in the list

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 an executive agency and trading fund of the Department for Business, Energy and Industrial Strategy are loathed to mention wind speeds from mountain sites such as CairngormCairn Gorm Cairn Gorm (Scottish Gaelic: An Càrn 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. 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.

It’s a funny old game

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!

Surprising North American anomalies

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.

Fog persists across Easter Ross

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.

My shadow cast a faint gloryGlory A glory is an optical phenomenon, resembling an iconic saint's halo around the shadow of the observer's head, caused by sunlight or (more rarely) moonlight interacting with the tiny water droplets that comprise mist or clouds. The glory consists of one or more concentric, successively dimmer rings, each of which is red on the outside and bluish towards the centre. Due to its appearance, the phenomenon is sometimes mistaken for a circular rainbow, but the latter has a much larger diameter and is caused by different physical processes. as I walked along the ridge.

Mild November in Iceland

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.

Recent temperatures in Qatar

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.

Bridge of Dee

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.

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.

Cold spreads its icy fingers eastward

The cold air over Scandinavia is squeezing it’s way eastward between low pressure over 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. 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.

2022 still on track for warmest year in central England

The year 2022 is still currently the warmest year in the CETCET Central 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 LTALTA Long 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.
