Forest fires are currently raging in the western United States. Dry thunderstorms are partly to blame. A meteorologist explains the phenomenon – and creates a gloomy forecast for Europe too.
- In California and other US states are raging Forest firesthat have already claimed numerous lives.
- In the United States is a debate about that causes flared up – and at the highest political level.
- A meteorologist explains one Weather phenomenon, which he also expects as an increasing danger for Germany.
California – That in the western United States Forest and bush fires rage is not uncommon. The duration and extent of the devastation, however, reach year after year worse dimensions. The current forest fires, which started in California and have now spread to other US states, have been going on since mid-August and the flames have not yet been extinguished.
Dry thunderstorms: weather phenomenon is becoming more and more dangerous due to climate change
Meteorologist Jan Schenk describes the opposite Focus Online a Weather phenomenon, which allegedly played a major role in the fire in California and can increasingly encourage serious forest fires in Europe and Germany: Dry storm. These would be favored by increasing global warming and also come to bear in the events in the western United States. So be with them Forest fires in North America Over 13,000 lightning strikes have been registered within ten days, says the scientist from Weather Channel.
The dangerous: lightning and thunder occur without rain and arise through Clouds of fire due to heat development on the earth’s surface. Schenk explains: “Fire clouds are created by extreme heat that is released in forest fires, for example. The heat ensures that very large air masses rise within a very short time and clouds form even when the sky is actually clear, including soot and ash. “
These clouds of fire would then Dry storm that already generate liquid, but this evaporates due to the extreme heat before it reaches the bottom. The striking lightning this meteorological peculiarity reignite new fires – so in Schenk’s opinion also with the raging fire in the United States.
The warmer and drier the region, the bigger it is Danger of dry thunderstorms: a dangerous cycle for humans. As a result, the natural occurrence occurs more frequently in areas that suffer from extreme heat. In the United States, 35 people have already been killed in the current forest fires, and many more are missing.
Forest fires due to dry storms are also a danger for Europe – and Germany
Is a similar scenario also in Europe possible? Definitely, says Jan Schenk in the Focus-Items – and not only in southern countries such as Spain or Portugal: For Germany, too, fire clouds represent an increasing danger: “However, it depends on the intensity of the forest fire. With increasing drought, especially in East Germany, fire clouds and thunderstorms are becoming more and more likely, ”reports the meteorologist.
Meanwhile, US President has Donald Trump when visiting the Forest fire areas in California again the Climate change denied. “It will be cooler again. You will see, “said Trump. The opposition presidential candidate Joe Biden then described Trump as “Climate arsonist“.
Climate change favors dry thunderstorms: the risk of forest fires increases – and so does human risk
According to the unanimous opinion of scientists, the forest fires in the western United States, which have been increasing in size for years, are the Warming of the earth’s climate jointly responsible. Of the Climate change therefore leads to always more drought in nature, which in turn is the Spread of flames accelerated.
Peter Wohlleben, forest expert, revealed in an interview with the Deutschlandfunkhow measures should look like so that the increasing fire risk can be put to a halt. And that shouldn’t please climate change deniers like US President Donald Trump:
Of the #Climate change be the trigger of the forest fires in the #UNITED STATESsays forest expert @PeterWohlleben. In the interview he suggests arming the forests against it. #Trump had in #California the #ClimateChange again denied. Here is the interview with Wohlleben: https://t.co/0O6UpFH1Zb

Another problem with regard to climate change: the Rise of the sea level. The Thwaites Glacier in Antarctica is one of the largest in the world. But it melts extremely quickly.
The main cause of forest fires is still people. Often carelessness is the result, sometimes arson. As with what happened in Moria, the largest refugee camp in Europe. (PF) * tz.de is an offer from the Ippen Digital Network
