Its intensity and behaviour also have a delayed influence on the actual weather layer – the troposphere. After a period of weakness in November, the polar vortex recovered, and now something is happening again. Here is an update! Klaus Marquardt 30.01.2026 13:44 weather international Weather NewsFlash World Every day, the weather makes headlines somewhere in the world, whether it's due to storms, new records or unusual phenomena. We cover the most significant events in detail in our own MeteoBlogs. We continuously summarise exciting and important weather news that is also relevant to the current situation in this NewsFlash. Reto Vögeli 27.01.2026 18:00 weather international The great cold wave of 2012 Fourteen years ago, one of the most severe cold spells in Europe began, with the first two weeks of February 2012 dominated by Frost. The cold spell hit Eastern Europe and the Balkans hardest, claiming several hundred lives. Klaus Marquardt 27.01.2026 13:14 weather international Significant snow and ice storm in the USA Arctic air masses are increasingly flowing into the United States from Canada. This is resulting in heavy snowfall in many places, while freezing rain is occurring in a transition zone. These ice accumulations in particular are likely to cause significant problems in some regions, with widespread power outages. Michael Eichmann 25.01.2026 19:00 climate international El Niño goes, La Niña comes El Niño conditions have prevailed in the equatorial Pacific in recent months. However, more and more cool deep water is currently reaching the surface off the west coast of South America and cooling it down. The transition from El Niño to La Niña is in full swing and will take place in the coming months. Klaus Marquardt 21.01.2026 12:27 weather international Harry Brings Storms and Heavy Rain to the Mediterranean Region Storm system Harry is currently bringing exceptionally large amounts of precipitation to wide parts of the Mediterranean region. In some areas, the measured 24-hour rainfall totals exceed the January average by three times. This precipitation event is accompanied by strong winds and high wave activity. Michael Eichmann 20.01.2026 14:26 astro international Strongest solar storm in over 20 years – Northern lights visible in the Alps Last night, there was a particularly strong solar storm –. According to the Space Weather Prediction Center (SWPC), it was the strongest storm in over 20 years. The colorful spectacle could be observed in many regions. Michael Eichmann 20.01.2026 03:12 weather lexicon Goodbye snow! What's happening there? Snow is a special element, a very special whim of nature. It's not just children who enjoy thick flakes and plenty of fresh snow for building snowmen. Most drivers, on the other hand, are less enthusiastic about it. How long a blanket of snow can last depends on several factors. In addition to the air temperature relative humidity also plays a role, and wind and rain are other possible snow killers. Klaus Marquardt 14.01.2026 12:25 weather lexicon Cold sum and Lake Freezing In cold winters, the freezing of lakes becomes a topic of interest. What does it take for a lake — large or small — to freeze over? The clear answer: sustained cold over a long period. As such very cold winter phases have become rarer in recent decades, complete lake freeze-ups have also become an increasingly rare phenomenon. Klaus Marquardt 07.01.2026 13:15 weather lexicon Cold air pools – Still pools, cool air A cold air pool is an accumulation of cold air in a depression. Temperature differences of up to 30 degrees can sometimes be observed within a few hundred meters. In addition to meteorological factors, the topography and the shape and depth of a valley are also decisive for the formation of a cold air lake. Michael Eichmann 06.01.2026 12:32 weather international Current sea ice extent in the Antarctic and Arctic The low point of summer sea ice extent is typically reached in the Antarctic between mid- and late February, while the winter maximum is reached in the Arctic in March with a slight delay. Conversely, the lowest sea ice extent is recorded in the Arctic in mid-September, while the greatest extent is recorded in the Antarctic. Currently, we are experiencing the lowest level of global sea ice extent on record. Michael Eichmann 19.12.2025 12:54 weather lexicon Wegener–Bergeron–Findeisen process The Wegener–Bergeron–Findeisen process describes the growth of ice crystals in mixed-phase clouds and is the main cause of precipitation in our latitudes. It also forms the basis for special cloud formations that arise through the transformation of supercooled water droplets into ice.
