In the Second World War, the bombs dropped by the Allies were so powerful that they temporarily raised the upper layer of Earth’s atmosphere – writes BBC News.
The bombs left ruins and ashes on the ground, but according to a survey, the wave of explosions could be felt even more than 1,000 kilometers above Britain.
Chris Scott, a scientist from the University of Reading, said that the discovery was completely overwhelmed. “All air strikes have released at least 300 lightning strikes,” he emphasized.
Researchers have analyzed daily reports of the Radio and Space Research Station in Slough, England. It was studied how the concentration of electrons in the upper atmosphere of electrons changed in the 152 European air raids of allies, during the bombing of the Berlin bombings and in the support of the Normandy invasion.
According to the data, the electron concentration dropped significantly when a bomb exploded and as a result the upper layer of the atmosphere warmed up. Slough was small, but the weakening of the ionosphere was perceptible, but the bombs were thrown hundreds of miles away.
Scott admitted, however, that this was a temporary effect and caused only a slight increase in temperature in the atmosphere. The effect on the ionosphere just kept on until the heat was gone.
Research, according to Scott, may help to better understand the impact of natural forces such as lightning, volcanic eruptions and earthquakes on the upper layer of Earth’s atmosphere. At the same time, it may be important to study the whole ionosphere as well.
The study was published in the journal Annales Geophysicae of the European Geological Society.
