Ionosphere Damaged By Bombing During World War 2

Posted on September 27, 2018

The bombs used by Allied forces during World War II were so large, they weakened the Earth’s upper atmosphere. The air raids turned towns to rubble and ash, but now new research shows shockwaves could be felt up to 1,000 km above the UK. Chris Scott, from the University of Reading said: “I was absolutely astonished [when I found out]. “Each raid released the energy of at least 300 lightning strikes.” It’s now hoped the research will give us a better understanding of how natural forces such as lightning, volcanic eruptions and earthquakes can affect Earth’s upper atmosphere.  Researchers studied daily records kept at the Radio Research Centre in Slough, UK. They looked at how the concentration of electrons changed in the upper atmosphere around the time of 152 Allied air raids in Europe – including raids on Berlin and those in support of the Normandy landings.  The data showed the concentration of electrons fell significantly when a bomb was detonated, which in turn heated the upper atmosphere. This caused a small but significant depletion in the ionosphere above Slough, even though the bombs were deployed hundreds of miles away. But Chris Scott admits “these were very temporary effects which heated the atmosphere very slightly.” “The effects on the ionosphere would only have lasted until the heat dissipated.”
