After the European heat wave of last week, the pendulum has swung to the other extreme.
Currently the weather pattern dominating Central Europe is bringing unusually cold air over the continent, and early this morning regions in a number of countries were hit by ground surface frost.
Parts of Belgium, Luxemburg, Germany, Switzerland, Austria and the Czech Republic saw surface frost – even down to the lower elevations (Belgium is hardly a mountainous region).
German site Wetter24 twittered here a map depicting the frosty areas gripping this 10th of July, 2015. Also see map here.
Swiss meteorologist Jörg Kachelmann here writes and supplies a link showing a German video reporting conditions that the German Eifel region woke up to early this morning. At the 1:50 mark the video reports:
We saw fields that were snow-white. That on the tenth of July I have never seen before. My colleague Fabian had also never seen this before. It just looked wonderful. We just thought that indeed we are not in autumn or spring; we are actually in July. These pictures impressed us, and that we found this frost.”
Apparently the “greenhouse effect” of atmospheric CO2 was unable to trap the heat and prevent frost from forming at ground level.
Yesterday Aonach Mor and Strathallan in Scotland saw frost. So did Blackpool and Exeter in England!
Central Europe and Great Britain were not the only places at the middle latitudes of the northern hemisphere that saw frosty conditions. ABC News here reports that “Tioga Pass was closed from 4 miles west of Jct 395 to the Yosemite National Park entrance gate, due to snow.”
Also the southern hemisphere has seen cold weather as well. The forecast for Australia is calling for below normal temperatures.

Looks like it may not have killed too many crops, at least not at 0300 UTC.
I didn’t see any comments about cold at the Tour de France site, it looks like they had a temperature of about 10C.
Eiffel region is an old volcano, elevated, they do mostly cattle crazing, not wheat production. The massive crop production happens in the plains of Northern and East Germany, which, due to the lapse rate, suffered no frost.
Hah, grazing, not crazing. Crazing is what they do in Berlin with the government politicians.
Groundfrost in eastern parts of The Netherlands too. -1.3 °C at the former Twente Airbase in Overijssel.
Re our Aussie cold snap I had a look at the southern jet stream location and the surface pressure map yesterday. They line up very well.
Jet stream location
That is one amazing loop of the southern jet stream right up from Antarctica to South Australia. No wonder the news is full of reports of good snow conditions in our ski fields this morning.
The sinuousity of the jet stream is enhanced in conditions of low solar activity. The heat waves and cold snaps that Europe has been getting lately is probably due to the same sinuousity and the blocking events which commonly occur in such circumstances. As usual the climateers try to ignore the Sun.
Pierre – A comment of mine has gone to spam, which I mention because you and Rick might be interested in it.
While on this, here is a link to the main menu page for CRWS Jet Stream Maps. Well worth looking at when you have interesting weather.
About half of my posts keep disappearing, or going into moderation.
Even the most benign posts. Very odd.
In the east of the Netherlands in the Twente area was also night frost and there it is even at lower altitude than Belgium.
Well, the unprecedented icy blast we been hearing about for 3 days passed through Adelaide last night, and the temperature this morning (in the Hills) is only 4℃ higher than it was 8 days ago.
I used to live near Canberra, and on November 22nd (1996 iirc) there was snow on the small hills between Canberra and where I lived.
(remember, in the SH this is pretty much the start of summer. Two days later it reached 35ºC during the day.)
A real Kodak moment.. wish I’d had one with me !
Little old cottage with smoke from the chimney, pine plantations covered with a coat of white powder.
Cool in more than one way !!
Cold in NZ also at the moment, snow in Auckland an unusual event. In south east Ozz it’s cold too, seems that polluting, greenhouse gas doesn’t work well in this hemisphere either?
This is why the slime balls are pushing hard for Paris. They know the climate is cooling. Once they have the agreement they think they will always get their $billions.
It would be comical, if the survival of mankind were not jeapordized by lock-step consensus models that have prevented us from understanding the fountain of energy that Copernicus reported at the gravitational center of the solar system in 1543 to start the scientific revolution.
Dr. Carl Rouse, was probably one of the most intellectually honest and certainly one of the most abused American astrophysicists of the past century.
He received a PhD in astrophysics from CalTech or Stanford in the late 1950’s, lived in LaJolla, CA with his lovely wife, and spent his career pointing out errors in the Standard Solar Model of a hydrogen-filled star.
Here are a few of his papers:
1964: “Calculation of stellar structure using an ionization equilibrium equation of state”, University of California, UCRL Report 7820-T.
1969: “Calculation of stellar structure”, in Progress in High Temperature Physics and Chemistry 2, ed. C.A. Rouse, Pergamon Press, Oxford, UK, pp. 97-126.
1975: “A solar neutrino loophole: Standard solar models”,Astronomy and Astrophysics 44, 237-240.
1983: “Calculation of stellar structure. III. Solar models that satisfy the necessary conditions for a unique solution to the stellar structure equations”,Astronomy and Astrophysics 126, 102-110.
1985: “Evidence for a small, high-Z, iron-like solar core”, Astronomy and Astrophysics 149, 65-72.
1995: “Calculation of solar structure IV. Results using a detailed energy generation subroutine”, Astronomy and Astrophysics 304, 431-439.
2000: “Inverse and forward helioseismology”, in Origin of Elements in the Solar System: Implications of Post 1957 Observations, ed. O. Manuel, Kluwer Academic-Plenum Publishers, New York, NY, USA, pp. 317-344.
