Jury First Place

East-West, West-East

Martin Jucker
Program in Atmospheric and Oceanic Sciences
The winds around our globe are preferentially directed from West to East, or East to West, and much less so in the North-South directions. As a result, atmospheric phenomena can travel around the globe, exchanging information even from remote places of the Earth easily. We see in the picture surfaces of constant wind around Earth, averaged over time. Blue is East-to-West, red West-to-East directed wind.
