The police had warned urgently on Tuesday of another night of traffic jams and asked drivers to bypass the A2 and A30 widely.
In other federal states, the police only reported sporadic ice accidents. In Schleswig-Holstein, the A7 in the Rendsburg-Eckernförde district in the direction of Hamburg was temporarily completely closed after a clearing vehicle had burned.
The re was only a short backlog because there were comparatively few cars on the road. “People have adjusted to the weather,” said a police spokeswoman.
Hoch »Gisela« brings very severe frosts of minus 20 degrees
The re should be less snow overall, but the temperatures will stay in the ice cellar. “High› Gisela ‹with a north-easterly to easterly current ensures widespread frosty temperatures during the day and at night for severe frosts of minus 20 degrees when clearing up,” explained DWD meteorologist Jens Bonewitz. From Thursday on – unlike before – the cold air will also completely prevail in southern Germany.
Early on Wednesday morning, the DWD reported severe frost between minus 10 and 15 degrees from northern Bavaria to the Mecklenburg Lake District, especially in central Germany, occasionally minus 25 degrees. In Thuringia, lows of down to minus 26 degrees were measured on Wednesday night. It was coldest in Olbersleben in Northern Thuringia, as a spokesman for the weather service announced. However, that was still a bit far from a Thuringian cold record. According to the DWD, this was measured on February 2, 1830 in Jena at minus 30.6 degrees.
The CSU politician told the German Press Agency on Tuesday: “In many regions of Germany the situation is gradually starting to calm down. It may take a while before everything goes back to normal. In some ways and in certain areas there are still impairments. ”
In the case of the railway, traffic on the important east-west connection between Berlin via Hanover and the Ruhr area rolled again. “However, restrictions and delays are still to be expected,” it said. Still nothing worked on some connections. From Dresden there were no long-distance trains in the direction of Leipzig, Frankfurt, Hanover and Cologne on Tuesday until further notice, as the railway announced on its website. Accordingly, no long-distance trains rolled between Hamburg and Kiel, between Hamburg and Lübeck and between Hamburg and Westerland on Sylt.
Shipping on the Mittelland Canal and Elbe Lateral Canal stopped
The massive onset of winter is now also having an impact on inland shipping in northern Germany. From Wednesday evening (6 p.m.) the Mittelland Canal and the Elbe Lateral Canal will be closed to shipping, as the responsible waterways and shipping office announced on Tuesday in Braunschweig. As a precaution, the icebreakers that are otherwise on these canals are withdrawn onto the Weser in order to break ice floes there in front of weirs – this is how the pressure that the ice loads on these facilities should be reduced, said a spokesman.
With a view to the announced permafrost period with up to minus 20 degrees, which should last for several days, the icebreakers could probably keep the Mittelland Canal and the Elbe Lateral Canal free anyway, according to the spokesman. As soon as the ice situation relaxes, the canals should be reopened for shipping.
Climate researchers consider more cold waves due to climate change to be conceivable
According to the climate researcher Stefan Rahmstorf, cold waves like the ones currently in Europe can become more frequent in the course of climate change – and the winters still warmer. “This can also be attributed to the fact that the polar vortex has become unstable,” said the head of the Earth System Analysis department at the Potsdam Institute for Climate Impact Research (PIK) of the German Press Agency.
The polar vortex normally rotates around the Arctic in the stratosphere, the second layer of the atmosphere, counterclockwise and also influences the weather in the troposphere, the lower layer of the atmosphere.
The n the cold air, which is normally trapped in this vortex above the pole, can go astray and migrate to the adjacent continents.” According to the researcher, it can happen that it gets very cold in North America or Northern Europe. “
The cold air is shifting, ”explained Rahmstorf. “For once, that extends to Spain or, in the USA, to Florida.”
According to the Potsdam researcher, evaluations of data from the past decades have shown that the number of days with unstable polar vortices has increased significantly. He therefore assumes that there may be more cold waves in the future. “We are already counting on the fact that the phenomenon will probably continue to increase,” said Rahmstorf.
