Vapour trails are artificial clouds that are the visible trails of condensed water vapour made by the exhaust of aircraft engines. As the hot exhaust gases cool in the surrounding air they may precipitate a cloud of microscopic water droplets. If the air is cold enough,this trail will comprise tiny ice crystals. Vapour trails may be visible for only a few seconds or minutes,or may persist for many hours depending on atmospheric conditions | |
