0 Aircraft brings snow?

As airplanes fly through clouds, they often punch holes through the ones that contain super cooled water, or water that has remained in liquid form below its freezing point. Latest findings say this might result in more snowfall near airports. Scientists used images from NASA’s satellite and weather forecasting models to examine how often this type of cloud seeding may occur within 100 km of six commercial airports, writes Kalyan Ray
Many times, these holes were mistaken for mysterious unidentified flying objects (UFOs), even though they are actually caused by airplanes flying through clouds. Now, researchers say, this phenomenon can lead to increased snowfall around many major airports around the world. The findings were published in the July 1 issue of the journal Science. As airplanes fly through the clouds, they often punch holes through the ones that contain super cooled water, or water that has remained in liquid form below its freezing point. The effect is similar to cloud seeding. Numerous private and commercial flights have been drilling holes and canals through clouds all along and in the process influencing the snow and rainfall below them. Led by scientists from National Center for Atmospheric Research, the new research focuses on these hole punch and canal clouds that form when planes fly through certain mid-level clouds, forcing nearby air to rapidly expand and cool. This, the scientists said, might result in more snow fall near airports compelling the authorities to de-ice the planes more. The consequences would be more pronounced in mid-and high-latitudes rather than a tropical country like India. Piercing of the cloud causes water droplets to freeze to ice and then turn to snow as they fall toward the ground, leaving behind odd-shaped gaps in the clouds. “Whether an airplane creates a hole or a canal in the clouds depends on its trajectory. When they climb through a super-cooled cloud layer, they can just produce a hole. But when they fly level through the cloud layer, they can produce long canals,” said NCAR scientist Andrew Heymsfield who led the study.
