NASA’s Aqua satellite captured long, narrow clouds Known as ship tracks or ship track clouds in the North Pacific Ocean.
The distinctive clouds form when water vapor condenses around the tiny particles emitted by ships in their exhaust. Ship tracks typically form in areas where thin, low-lying stratus and cumulus clouds are present. Some particles generated by ships, especially sulfates, are soluble in water and serve as the seeds around which cloud droplets form.
