Timelapse footage of virga falling from clouds, causing localised microbursts. Virga is precipitation that evaporates before it reaches the ground. The evaporation cools the air, making it denser, and it forms a downrushing column of air that produces strong winds at the surface. Such conditions are hazardous for aircraft. Filmed in Colorado, USA, in spring. Mastered from originals, frame size 1280x1080.
