Contrails coming from battle aircrafts have been shown to affect the English weather and it has traces as back as the World War II

During World War II, bombing raids were all across the English sky and behind them, huge contrails could be seen delaying there.

According to modern science and the researchers involved in a new study, those contrails contributed greatly to the change of the English climate. As you can imagine, the researchers analyzed data from a period when the English sky was covered with bombing raids. Between 1943 and 1945, after the United States Army Air Forces joined the battle against the German Nazi, Adolf Hitler and even though in the early years of the 1940s the English sky was clean, since this moment, it all turned black with bomb raids. According to the scientists involved in this new study, the aircrafts which raided the English sky have doubtlessly changes the weather especially because they affected the energy coming into and out of the Earth at that location.

For those who do not know, contrails are actually straight, white lines which delay behind aircrafts due to the condensation of the droplets which are exhausted by the aircraft’s engine. The trick with these contrails is that they can last for days and given that they look so much like clouds, after a few days they cannot even be told apart from each other. According to the scientists, contrails have very complex effects on the surface of the Earth. First of all, they can reflect the sun light and thus cause cooling. Secondly, they can trap long-wave radiation for a long time and thus, cause the surface of the Earth to get hotter and hotter.

Rob MacKenzie, the lead researcher of the study, along with his colleagues got to the conclusion that the best day to show how these contrails affect the Earth was the 11th of May, 1944, when a huge raid took place on the English sky. Of course, the scientists analyzed data from many more aircrafts raids, but this one shows the effects the contrails have on the Earth surface the best. During this particular raid, 1,444 aircrafts took off into a clear sky and their contrails remained on the sky, suppressing the morning temperatures and thus, causing a change in the English weather. According to the scientists, more studies have to be made on the issue in order to determine exactly what and how the English weather changed and how would have it looked were not for the huge aircraft raids during the World War II.
