Sea spray display
What looks like a scene from a Michael Bay film is simply water.
This false colour image of spray droplets being ejected from a breaking wave (left side of frame) was taken in a laboratory. The droplets are moving from left to right and the biggest are around one to two millimetres across.
It was taken as part of a study, published in the Journal of the Atmospheric Sciences, into how monitoring sea spray might help forecast hurricanes and tropical cyclones.
Evaporation of sea spray is thought to contribute to the transfer of heat from the ocean to the atmosphere, which accelerate winds in a storm.
