Waves, Rossby

NASA RESEARCHERS AT the Goddard Institute for Space Studies describe Rossby Waves as “slow-moving waves in the ocean or atmosphere, driven from west to east by the force of Earth spinning.” These are naturally occurring phenomena first recognized in 1939 by a Swedish-American meteorologist named Carl-Gustav Rossby. These waves, which are found in both the atmosphere and the oceans, are important mechanisms for the redistribution of energy around the globe. In three sections, this essay describes the formation of atmospheric Rossby Waves, oceanic Rossby Waves, and the connection between Rossby Waves and global climate change.
