On remarque un poussée d'air froid sur l'Est du Canada, mais bien moins féroce que la précédente. Chez nous aussi, en europe de l'Ouest, nous subissons une poussée mais rien de bien méchant.  Nous devrions retrouver un flux d'Ouest, doux et humide, en fin de semaine, mais c'est bien entendu à confirmer.

 

Les températures, ce soir, à 18h, en Europe. De faibles gelées sont à prévoir à l'intérieur des terres au petit matin. Plus froid en montagne, bien entendu....

Mise à jour du 22 Janvier au soir

 

Le Jet Stream laisse entrevoir une dégradation des températures pour les prochains jours.

Nous voyons une nouvelle poussée froide sur l'Amérique du Nord-Est; et une sur l'Europe. Le Jet sStream en est dévié vers le Sud ( flèche verte ), ce qui prouve que le courant est puissant. A terme, il devrait percer, mais sur du froid, et donner de la neige dans quelques jours.

 

Les températures, elles, baissent ( 22hUT, pour ce soir ).

View from space: World’s largest offshore wind farm

Satellite view of the London Array wind farm, 20 kilometers (12 miles) from England’s coast, where the River Thames meets the North Sea.
















The London Array, the planet’s largest offshore wind farm, became fully operational on April 8, 2013. It has a maximum generating power of 630 megawatts (MW), enough to supply as many as
500,000 homes.

NASA’s Landsat 8 satellite captured these images of the area on April 28, 2013. The top image is a closeup of the area marked by the white box in the lower image. The little white dots in the
top image are the wind turbines. You can also see a few boat wakes.


To date, the London Array includes 175 wind turbines aligned to the prevailing southwest wind and spread out across 100 square kilometers (40 square miles). Each turbine stands 650 to 1,200
meters apart (2,100 to 3,900 feet) and 147 meters (482 feet) tall. Each is connected by cables buried in the seafloor, and power is transmitted to two substations offshore and to an onshore
station at Cleve Hill.
