Aircraft can change the weather

When the plane flies through and creates holes in the clouds, it can change the weather around the airport areas located in high latitudes, even causing rain and snow, according to a study. new research published in Science magazine.

Based on data collected from seven airports located in high latitude areas, scientists found that the planes created holes in the clouds with a diameter of several tens of meters or more, even expand tens of kilometers within a few hours.

New Scientist page quoted Andy Heymsfield - a research team member working at the US National Center for Atmospheric Research in Boulder, Colorado, USA said: ' This is a mystery'.

To clarify the issue, Mr. Heymsfield and his colleagues used Meteorological Satellite (GOES) in conjunction with the use of the Weather Research and Forecasting (WRF) computer model to track 92 holes. clouds in the sky in Texas for 4 hours on January 29, 2007, with the main agents causing them are aircraft, including large passenger aircraft and military aircraft.

The team found that, under normal conditions, clouds have temperatures ranging from 0 to 40 degrees Celsius and contain droplets of super-cold ' hanging ' liquid suspended on them. These supercooled liquid droplets persist for a long time without any impact.

However, an aircraft equipped with jet engines or propellers when flying through the sky will cool the clouds. At this time, the temperature in the clouds is reduced, ranging from - 10 to 20 degrees C.

The process of cooling these clouds is more than enough to activate, converging supercooled droplets and forming ice crystals. They grow heavier and heavier, causing rain or snow.

Scientists say that such holes will cause more snowfall during the winter months, and this sometimes leads to a flight delay. However, they believe that these holes will not have a big impact on climate change.

Below is a picture of the holes created by trans-plane aircraft and recently captured by scientists on Live Science.
