Winter 2005-2006: very cold in the East of France

[Former Oceano]

Indeed there were some in particular in the lower Dryas. If this topic interests you, we talked about it at the end of last year. You can refer to this subject:

Different theories are proposed to describe the climate on our coasts. Some speak of the effect of the Rockies on the Jet Streams causing ripples and preventing polar currents from reaching us. Others attribute this to the Gulf Stream (which I think is more likely given the enormous amount of water and heat energy carried by this 'sea river').

The concern is that it has already started to slow down and that at a certain point it will stop. Natural phenomena are often catastrophic (i.e. brutal) and we will surely not have a regular decrease of the kind -5% per year for 20 years ...

Likewise, the effects will surely be felt before the full stop, but beware, it will not be like in the movie 'The day after': nothing so brutal, luckily.

thank you ex-oceano.

I had taken a look at your exchanges, I remember.

It was just before I signed up for econology, and I found this information very interesting. There is surely a part of the answer to this prolonged dry winter! ??

An explanation of cooling 8200 years ago:

and another explanation on the Gulf Stream:

and again "the Gulf Stream is not weakening":

........Not easy to find ! between affirmations and contradictions, is there not haste in certain scientific affirmations?

Indeed it's hard to navigate, especially if we speak at different scales or locations.

This Article here shows the variation of the speeds of the different branches of the current.

In addition, their study seems to be based on the Feroes Islands and Iceland. Freshwater inflows in this region seem to be of glacial rather than fluvial origin. However, if we have cooling of the North Atlantic, we will have less melting and therefore less fresh water released ... On the other hand, the heavy rainfall in central Europe and northern Russia (with the gigantic floods of the latter years) are not taken into account. Indeed, they flow much further to the east, into the Baltic Sea, the North Sea and the Arctic Circle ... These freshwater discharges are monstrous and will not be slowed down by a cooling of the temperature of the water because they are of atmospheric origin ...

Last point, in the article that jean63 delivers to our knowledge, we can read:

The Gulf Stream is therefore not weakening, it should continue to circulate with the same force along the northern coasts for at least ten years.

They talk about the Nordic coasts (which) for a period of 10 years (barely 10 years - that's not much) ...

this part of your article is quite convincing:

at the edge of the ice cap, the cooled waters sink into the deep layers of the ocean. This deep North Atlantic water, which forms the Labrador Current descending along the American coast, has seen its flow drop at great depth (between 3000 and 5000 meters) by 50%.

Scientists have deduced that the North Atlantic drift, which reaches as far as Europe, recorded a decline in its flow from 20 million tonnes of water / second in 1957 to 14 million tonnes of water / second in 2004. .

«The heat it transports makes a substantial contribution to the moderate climate of maritime and continental Europe and any slowdown in ocean circulation would have profound implications for climate change, ”the study notes.

“Previous studies over the past 50 years have shown relatively constant ocean circulation and heat transport across the 25th parallel. This is why we were surprised that the ocean circulation figures in 2004 were so different from previous estimates, ”noted Professor Bryden..

So we can expect harsher and / or longer winters in France. The avalanche which occurred yesterday at Mont-Dore on the west face of Sancy and which completely covered the slopes until the cable car departure, is unheard of; there was already a fatal avalanche at the start of the season at Lioran. We never heard of avalanches in the Monts d'Auvergne.

Could this be the start of the festivities?
