boxman: Well, maybe someone can teach those experts to read? I hear those audio books take a long time to listen to. Hope your humor has improved. Summer still is here, so stop looking longinly at those ice skates for awhile....

Real clear meteorology: Real clear meteorology put into practice: What is the point in posting that?? This thread is about temperatures hare and how the jet stream has caused change over north western Europe. I said last summer how a similar pattern caused your heat wave, while it caused the exact opposite here. The fact is still that global warming theory predicted the opposite trend with jet streams moving northwards instead of southwards. Now for several years in a row it has been more south and more unstable than normal. I am still expecting it will be a few years before temps really start dropping on a global scale.

Boxman, it seems obvious (as the simple graph tells you) that the ridges of hot and cold air will extend further than in the past in either direction. The ridges as whole will also represent higher and lower air pressures. This will cause all kinds of woes, such as extreme frontier systems between the two, with the associated extreme rain.

Met Office reports Britain has had the wettest summer since 1912 and a frost is expected tonight in parts of the Midlands, highly unusual for August.

boxman: From all appearances, it will be several years before you get to enjoy "heat" again.
Keep the woolies in good shape.

"And it has now been over a damn year since we had even ONE single summer day with temps of 25c or higher. " You have in fact had one day, Aug 16th, when the temp was 26C in Trondheim (Vaernes). In June you reached 24C on one day. www.wunderground.com/history/airport/ENVA/2012/8/8/MonthlyHistory.html--- If I may, let's review some other European locations: the Dolomites, and the Alps in general. The summer 2012 heatwave melting at the Italian Alps has revealed some WWI ammunition on a 3,200 meters peak Cima Ago di Nardis: www.primaguerra.it/index.php?option=com_content&view=article&id=341:cima-ago-nardis-ritrovamento-munizioni-grande-guerra&catid=3:ultime-notizie&Itemid=213Google Translate is doing its best on www.ilsecoloxix.it/p/italia/2012/08/31/APkxg0KD-arsenale_scongelato.shtml: Trento - with exceptionally hot summer. And the glaciers are melting. Not only with consequences for the climate. Also return relics of the past. S crimson are 200 weapons of the First World War. He found the Guardia di Finanza of Trentino in the mountains at almost 3,200 meters above sea level. Were not far away as the crow flies from the popular holiday destinations of Pinzolo and Madonna di Campiglio. But they were in a place not easily accessible, where the mountain rescue of the financial police (SAGF) was doing an exercise, under the Top Ago Nardis.
It is another of the many obvious signs of how the hot, extremely strong in the north of Italy and also at high altitudes, has caused changes in the alpine landscape, Dolomites included. This year seems to be more than usual. On Mount Pasubio, on the border between the provinces of Trento and Vicenza, were recently recovered the remains of trenches, posts and a system of tunnels of the same conflict. But that is now history.
From the scientific point of view, the data confirm an excellent dissolution and also the Finance explains the discovery of the bombs with thermal stress, ie the strong heat: it is 200 grenades 85-100 mm in size, weighing in at 7 or 10 pounds each. (my emphasis) Heatwave in Rhone-Alpes in France: www.guide2rhonealpes.com/news/379/Rhone-Alpes-News---Heatwave-in-the-Rhone-Alpes "The recent heatwave saw new seasonal highs set in several areas, including Burgundy, Jura and the Alps. The temperatures passed the previous records set in the heat wave of 2003, the hottest on record since at least 1540, and which claimed the lives of almost 15,000 people." www.thelocal.fr/page/view/france-heatwave-starts-to-cool

Actually we did not. It is true that we had ONE day were station measured 26c on værnes, but that station is located outside of trondheim where the hottest day was in may with 24.6c: Last 12 full months: Highest temperature was 24.5 °C (24. May. 2012) and the lowest -13.7 °C (1. Feb. 2012). Highest daily precipitation was 38.9 mm (23. Mar. 2012). So yeah that is over a year without a single summer day by international standards, which has not happened during my lifetime.

"Actually we did not. It is true that we had ONE day were station measured 26c on værnes,"
I think you have some internal discord in your statement.
As stated, 26C was the maximum for the summer 2012 as officially measured for Trondheim Norway, and that exceeds 25C, even if for one day only.
If you have a better official station that weatherunderground does not list, by all means let's have a look.

"In general the værnes one is pretty accurate though, but sometimes there is differences. " The airport's height (30 kms to the east along the same fjord) is 17 meters, the "city centre" station is at 127 meters. With the lapse rate of 1C per 100 meters, that alone should create a difference of about 1 C cooler for the "city centre" station. As I'm a stubborn person by nature, I surveyed through weatherunderground some private weather stations transmitting over the interwebs in Trondheim city centre (the elevation would seem to me be pretty low, but this is Norway after all so I can't tell) There is something weird in their software and for some stations it will always revert to the airport data seemingly no matter what I do. Anyways: Kalvskinnet, Trondheim (as close to the city centre as you can get I'd think): 26.7C farm9.staticflickr.com/8295/7967781624_de29404229_c.jpgVikhammer (about halfway to the airport on the coast): 25.7C farm9.staticflickr.com/8320/7967801558_6a5e6b1771_c.jpg

There is another variable that you should take into account besides the lapse rate. I don't know the formal name for it, but up here in the north, proximity to the ocean plays a larger role then the lapse rate. Think about it this way. Anchorage, AK is on a peninsula. Palmer, AK is just 40 miles away, and at about the same altitude. Just a few feet above sea level. Yet in the Winter Palmer is usually 10 to 15 degrees colder (f) then Anchorage. In the Summer they are almost always warmer then we are by the same amount. The ocean is a heat sink in the summer, and gives it up in the Winter...
