The Cold’s arrive again. Only three weeks ago our post “The ‘Beast from the East’ – Off-Shore windfarms pave the way” discussed the sudden cold snap in Europe, because it is highly possible that human activities at sea, contribute to unexpected low temperatures influx from the Far-East. The explanation is simple: As soon as the reginal seas across Europe have lost too much of their heat stored during the summer season, cold air from Siberian can reach Europe and establish reign for days or weeks, respectively delay the arrival of spring.
The last few days weather development support the thesis. Europe’s spring, respectively the months April, May and June are likely to show sub-temperature, as indicated in Fig. 1. Already forthcoming April the forecast indicates a significant negative anomaly (Fig. 2), with the North Sea and Baltics in focus. Why does it happen exactly in the regions? The explanation presumably stems from the various anthropogenic activities at sea. Lengthy discussed HERE:
Temperature drops of 10 degrees Celsius can be expected as the cold air arrives Friday into the weekend. “Sunday will be the coldest day with maximum temperatures struggling to lift above freezing across the U.K., Belgium, the Netherlands, Germany, northern France and southern Scandinavia.” Wind chill values may dip as low as minus 10 degrees Celsius – equivalent to the mid-teens Fahrenheit.
With cold air blowing over the North Sea and an upper-level pocket of cold air, areas of snow showers and squalls are once again a likelihood to the U.K, Ireland, northern France and southern Scandinavia this weekend.
Difference from the cold snap three weeks ago.
The cold air will work its way south and west into most of the rest of Europe later in the weekend (17/18 March). It is in this part of Europe where the cold will persist the longest well into the week of March 19-23. This pattern will also generate areas of snow that will persist through much of that week in southern, central and eastern Europe. Some of that snow will be moderate to heavy, not simply in the Alps, but also from parts of Germany and Poland to the Ukraine.
The phrase “Beast from the East” refers to the fact this cold air arrives on strong winds blowing east-to-west from Scandinavia over the North Sea into the British Isles and western Europe.
