From the NASA Goddard Space Flight Center. A fascinating set of 3 synchronized movies showing evaporation, water vapor, and precipitation on a flattened image of the globe.
NASA doesn’t go into a whole of detail about exactly what the animations are showing – or to what extent they capture real events or are mathematical models. Only that…
The three animations of atmospheric phenomena were created using data from the GEOS-5 atmospheric model on the cubed-sphere, run at 14-km global resolution for 25-days. Variables animated here include hourly evaporation, water vapor and precipitation.
As someone mentions in the comments on NASA’s Flickr page, in layman’s terms they are, well, kind of hypnotizing.
