February 26-28: Extreme Artic Cold In Europe

It’s Tuesday and light snow is falling. There is a pale sunlight at the same time as the sky is mostly overcast. Shortly before the begin of the “meteorological spring” winter arrived in Europe. Seen from my window the nice winter setting outside doesn’t tell about the extremes which befell Europe over the last days.

After a moderate winter in Middle Europe, a Siberian cold front reached Europe. It happened what had been forecasted in weather models days before. However, there is a surprising intensity of extreme weather these days in Europe: The UK was hit by lots of snow, and Rome is seeing snow for the first time in many years. Last night temperature was – 27 Celsius on top of the Zugspitze, Germany’s highest mountain. In Eastern Europe, there are very low temperatures and the danger increases particularly for homeless people. In Germany, there isn’t a lot of snow so far but the strong wind from the North-East makes it a bit of a challenge to stay outside for a longer time.

The blast of cold air from the artic has been already labeled: “The Beast From The East”. Scientists say that this happened due to “a freak warming around the North Pole”. They are somewhat alarmed about the retreat of Arctic ice during winter and the high temperatures. This weather pattern allowed the cold air on the other side to reach huge parts of Europe. There are now condition in Europe in some places which would normally apply to the polar region. It is not clear if global warming is causing this strange pattern or if other reasons are responsible.

However, very cold temperatures are not so unusual in February but what’s unusual is these sudden drops in temperature. They occurred also over Northern America in the last years and remind us sometimes on the “Day After Tommorrow” scenario in Roland Emmerich’s movie, even we can’t compare this to the “new ice age”.




In this weather-conditions, there are many things to see. Even if there is not a frozen-waterfall nearby, wind, snow, and ice create interesting patterns or sculptures.

It is always promising to look what happens at a lake or a river. Here are some pictures which were taken at the Bavarian lake Ammersee.

Weather services announced warmer temperatures for the end of the week, but in these times we never know what exactly will happen. Thus, there is still time to do more pictures. Staying outside is normally not a big problem with the right clothes, however, some common problems need attendance: cameras and tripods get extreme cold and it’s painful if you have to take off your gloves. Batteries don’t last too long in the cold, but these problems could be handled with a little preparation, for example, do apertures settings and other settings before going outside if possible.

In the surrounding hills around lake Ammersee there are many open fields and spruces. The wind and the ice led also to bizarre formations.

Berlin, August 1, 2017: Spectacular Evening Sky

On August 1 again a hot air mass met a cold air mass over Germany. Subsequently, there was an air mass limit. Air mass limits are often the reason for severe weather events like extreme thunderstorms with tornados and flooding or downbursts.

(A good definition what an air mass is could be found at the UK met office:http://www.metoffice.gov.uk/learning/learn-about-the-weather/how-weather-works/air-masses.)

Severe storms were expected, the weather service also issued a warning for Berlin. In the afternoon and evening, a line of thunderstorms appeared. There was severe weather in Brandenburg and many other areas. However in Berlin after a short time of rain, the turbulent sky opened a bit and a red evening sun was illuminating the dramatically structured clouds.




Many people stopped and took pictures of the unusual weather situation. Of course, evening-glow happens a lot but this dramatic sky was extraordinary. One reason for this impressive sky is that if you have a weather situation with thunderstorms close or developing there is a chaos in the atmosphere. There are several levels in the lower and higher atmosphere with different clouds and there is a lot of circulation.

 

The impressive scenery lasted till it became dark. There was only a little wind and it was still very warm in the city during the night. Some sheet-lighting could be seen later but the bigger storms happened more in the South.

It was a relief after two severe storms with extraordinary flooding hit the city two times before.

But summer 2017 is very unpredictable in Europe. Two days later a very strong cell did damage in the South of Berlin and later in August Austria suffered from storms with heavy rain followed by mud-slides.

On the south-side of the Alps in Italy there are still heat-waves. As mentioned before these weather-patterns fit in the scenarios developed by scientists about effects of climate change.

 

There is a good-viewpoint between railway station “Gesundbrunnen” in Berlin and the well-known Bornholmer Straße. The pictures below were taken from a small bridge named “Schwedter Steig”. I had seen that bridge a couple of times when using the train. Its always useful particularly if you want to do weather-pictures to have an inventory of good view-points before, since if an interesting weather pattern occurs there is no time to search for a good place with a lot of open skies to take pictures or videos.

Berlin, July 22, 2017: The Flood Again

Again scenes looking like from Roland Emmerich’s “Day After Tomorrow”. Roughly three weeks after the flooding with lots of damage the German capital was again hit by severe weather. A thunderstorm and torrential rain hit the city on Saturday afternoon when many people were celebrating the Christopher-Street-Day-Parade. Luckily it didn’t affect much of the parade, but also this time there was a state of exception.

In some parts of the city particularly in the North and North-East but also in the South-West a lot of rain came down, and in Pankow, a storm left a trace of destruction. Trees fell on cars, the S-Bahn Linie 2 commuter train was interrupted in the North for some time, also the tracks of a street-car were affected.

Also again there was a lot of water on some streets turning them into canals like three weeks before. It’s noteworthy that often car drivers are obviously not conscious about the danger for their cars and perhaps also for themselves: if you drive into a puddle of water and the level of water is high enough its possible the water is sucked into the air filter. Subsequently, the engine could be completely destroyed. Cars could also become deadly traps if the car is drowning in a flooded underpass and the doors cannot any longer be opened.

If possible try to avoid driving when these type of flash-floods occur which are a novelty in Germany with this kind of intense rain and also the fact that we have now repeated events of that kind in shorter time-periods during summer.

It certainly looks like one of the predicted effects of climate change; for a long time, scientists warned of higher levels of moist air in the atmosphere during summertime. These wet air masses can lead to more extreme weather like heavy thunderstorms and extreme rain.

Obviously, it’s not yet possible to have a more precise forecast or nowcast about thunderstorms with extreme flooding. Forecasts were very precise this day about the time when the bad weather was supposed to arrive around 3-4pm in the afternoon, and there was also a warning about heavy rain, but it’s, of course, impossible to say where exactly the most extreme events do happen.

For example, the south-west of Berlin is usually less affected by severe thunderstorms as the North but there are exceptions from the rule. This time an underpass in Zehlendorf (South-West) got flooded. During the last event, the biggest mass of rain hit quarters in the west (Wilmersdorf) and a city north of Berlin, Oranienburg, where thunderstorms are more often.

Luckily the rain didn’t last as long as two weeks ago. Therefore it was another extreme day for police and fire-starters but it should be less damage as during the previous extreme weather event.
