Researchers say impact of WWII bombing raids felt at edge of space

Bombing raids by Allied forces during the Second World War not only caused devastation on the ground but also sent shockwaves through Earth's atmosphere that were detected at the edge of space, according to new research. University of Reading researchers in England have revealed the shockwaves produced by huge bombs dropped by Allied planes on European cities were big enough to weaken the electrified upper atmosphere -- the ionosphere -- above the U.K., 1,000 km away. The results were published Sept. 25 in the European Geosciences Union journal Annales Geophysicae.

Scientists are using the findings to further understanding of how natural forces from below, like lightning, volcanic eruptions, and earthquakes, affect Earth's upper atmosphere.

Chris Scott, Professor of Space and Atmospheric Physics, said: "The images of neighborhoods across Europe reduced to rubble due to wartime air raids are a lasting reminder of the destruction that can be caused by man-made explosions. But the impact of these bombs way up in the Earth's atmosphere has never been realized until now."

"It is astonishing to see how the ripples caused by man-made explosions can affect the edge of space. Each raid released the energy of at least 300 lightning strikes. The sheer power involved has allowed us to quantify how events on the Earth's surface can also affect the ionosphere."

In the study, researchers looked at daily records at the Radio Research Center in Slough, U.K., collected between 1943-45. Sequences of radio pulses over a range of shortwave frequencies were sent 100 to 300 km above the Earth's surface to reveal the height and electron concentration of ionization within the upper atmosphere.

The strength of the ionosphere is known to be strongly influenced by solar activity, but the ionosphere is far more variable than can be explained by current modeling. The ionosphere affects modern technologies such as radio communications, GPS systems, radio telescopes, and some early warning radar, however the extent of the impact on radio communications during the Second World War is unclear.

Researchers studied the ionosphere response records around the time of 152 large Allied air raids in Europe and found the electron concentration significantly decreased due to the shockwaves caused by the bombs detonating near the Earth's surface. This is thought to have heated the upper atmosphere, enhancing the loss of ionization.

Although the London "Blitz" bombing was much closer to Slough, the continuous nature of these attacks and the fact there is far less surviving information about them made it more challenging to separate the impact of these explosions from natural seasonal variation.

Detailed records of the Allied raids reveal their four-engine planes routinely carried much larger bombs than the German Luftwaffe's two-engine planes could. These included the "Grand Slam," which weighed up to 10 tons.

Professor Patrick Major, University of Reading historian and a co-author of the study, said: "Aircrew involved in the raids reported having their aircraft damaged by the bomb shockwaves, despite being above the recommended height. Residents under the bombs would routinely recall being thrown through the air by the pressure waves of air mines exploding, and window casements and doors would be blown off their hinges. There were even rumors that wrapping wet towels around the face might save those in shelters from having their lungs collapsed by blast waves, which would leave victims otherwise externally untouched."

"The unprecedented power of these attacks has proved useful for scientists to gauge the impact such events can have hundreds of kilometers above the Earth, in addition to the devastation they caused on the ground."

The researchers now need members of the public to help digitize more early atmospheric data to help understand the impact of the many hundreds of smaller bombing raids during the war, and to help determine the minimum explosive energy required to trigger a detectable response in the ionosphere.
