A new study by researchers including those at the University of Tokyo revealed that atmospheric gravity waves play a crucial ...

That’s what happened to Texas last week: One of those Rossby waves brought cold Arctic air all the way south – and then stuck for a while. The jet stream itself didn’t stop.

The rotation causes the Coriolis effect, which influences the direction of winds and ocean currents. Rossby waves are large waves in the atmosphere that form because of the Earth's rotation.
