It can Christmas in Europe we have combined them with snow and cold, but this is not going to happen this year, nor in Greece. An important and large-scale meteorological phenomenon is underway in the North American region, which is expected to have significant effects on the weather in Europe during Christmas, according to the latest data, as reported by the meteo of the National Observatory of Athens.
On the weekend of 24-25/12 and until at least the middle of next week, high pressure is expected to prevail over most of mainly southern Europe, as well as significant rise in temperature in most of Europe, including Greece.
A significant absence of precipitation is expected mainly in the Mediterranean region, including our country, while more rainy weather is expected mainly in West/Northwest and Central Europe.
Snowfalls they are expected to occur only at high altitudes mainly in the Alps, while it is also possible that snowfalls will occur even at low altitudes in northern parts of Great Britain.
The explanation
But how is this year’s warm Christmas explained? The atmospheric circulation over North America during Thursday 12/22, “steered” by the position and intensity of a jet stream (a strong current of air at a height of about 10 kilometers from the Earth’s surface), favors the transport of very cold gas masses , of polar origin, from the Canadian region to the southernmost latitudes of the USA to the Gulf of Mexico.
At the same time, the specific arrangement of atmospheric systems will favor the formation of an explosive cyclogenesis (a deep barometric low) in the greater Great Lakes region on the US-Canada border on Friday 12/23.
According to the latest forecast data, the formation of this strong barometric low in the North American region is expected to have significant effects on the more easterly atmospheric circulation over the North Atlantic and Europe during the coming days. More specifically, the explosive cyclogenesis over North America is expected to cause a significant oscillation of the jet stream over the North Atlantic region and Europe. This strong stream oscillation is often associated with extreme and prolonged weather conditions over large areas.
