Rossby Wave

Rossby waves are planetary waves of winds in the atmosphere. These are meandering jet streams, in the North Atlantic region, caused due to the rotation of the earth. It is formed due to variation of the Coriolis Effect with latitude and pressure gradient. They flow from west to east. Recently, scientists discovered their influence on Indian monsoons. The Rossby Waves disrupts the flow of monsoon winds and may lead to non- El Nino droughts.
