photos of high altitude rocket trails at the vandenberg air force base in california, formed as water and unburned particles of the rocket propellant condense, freeze and then expands in the less dense upper atmosphere. winds high in the atmosphere then pull, twist and turn the exhaust of the rocket into the streaks seen here.
while the exhaust plume hovers in the stratosphere and mesosphere, it becomes illuminated by the high altitude sunlight. they are rare because they require a launch time around sunrise or sunset, as well as clear skies. the particles in the exhaust must also be of a certain size to create the pinks, blues, greens, and oranges.

a waterfall of mist flowing over golden cliffs of west bay in dorset. noted the videographer, “when i walked on to the beach i couldn’t see anything because of the fog. i could barely see the top of the cliffs. i sent up my drone well above the cliffs to see what was happening and i could see the fog just flowing over the cliffs like a waterfall.
normally, hot air will cool as it rises, but the opposite can sometimes occur in what is known as temperature inversion, where hot air high up acts as a seal to keep cold air and fog trapped below, creating the scene of a river of fog seeming to flow into the sea below. (x)
