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.
