It is the South West African heat that is coming !!
but www.dlsc.ca at 1000m altitude, it is very cold, -15 ° C last night, and they heat up with the summer heat kept warm at 55 ° C for the winter !!!

Glaglagla! -17 ° C here! -14 ° at 9am!

There is once again an "inversion" of the winds: the icy polar air is at the origin of the current cold wave which is falling on Europe (exactly as in December 2010).

A theory of explanation was made above last winter: modified polar albedo which generates anticyclone and depression in places where they were not used to be and therefore it results in different weather winds: from the North East instead of West!

This kind of reversal has already existed; here is a .pdf on the coldness of winter 56 with nice photos! and a map of the isobars of the time (probably obtained by a current model in retro processing starting from the actual measured values)

It was much worse and may be from a similar phenomenon but probably with different causes ... a solar flare / overactivity?

We, with the "progressive but permanent" melting of the sea ice and permafrost, we can expect such phenomena of more frequent cold waves ...

In 1956 it was 10 ° C lower, over almost a month !!

I remember the Seine transformed into polar pack ice, huge blocks of ice 3m in size !!!

We have short memories;

Currently classic cold remaining much hotter than before !!

That in the past I don't know: not all winters of the XXI century were that of 56 !!!

The .pdf talks about it with photos, look at it!

Here this morning, on the Basque coast, we are far from your -14 ° Christophe, the fleet and the greyness are linked in positive temperatures between the gusts of wind, and not yet seen the snow this year .... (except on the Pyrenees of course). : Mrgreen:

In my childhood in Lorraine we had much more snow and cold than today.
We had up to -25 under shelter near Metz. I saw my mother emptying a can of fuel oil on the portal taken by the ice to be able to open it.
We stayed in the harbor with the school bus between Orny and Mécleuve in the open country because the gas oil had frozen.
In short the cold can be much more biting than today.

New article to explain this particularly cold "spring" 2013 in northern Europe ... here it is the coldest weekend at the end of March since 1916 ...

The explanation here we already gave in this subject more than 2 years ago ...

The Pole heats up, Europe quails

The cold prevailing here does not contradict global warming.

Weather and climate are worlds of apparent paradoxes. Thus the source of the cold which freezes our countries and makes spring a distant prospect is undoubtedly to be found in ... the warming of the Arctic due to the greenhouse effect. "The persistent cold that we know has its origin in a powerful anticyclone based on Russia and Siberia, explains David Dehenauw, meteorologist at the IRM. This high pressure which sends us freezing air blocks the depressions which usually arrive from the Atlantic and brings us this season softer and humid air. From time to time, one of them manages to cross the barrier of the high pressure; but it is not powerful enough to drive out the cold. Result: it is snowing. The high pressure is particularly strong because it has snowed heavily on Siberia and it has been very cold there. "

And what makes you think that it has to do with the Gulf stream?

Earlier in this subject, we spoke of a modified polar albedo ... which modified the prevailing winds ...

This is exactly what is happening in Europe these days: North East polar wind ...
