Abstract:
This work is focused on the jet streams study. The jet stream consists of ribbons of very strong winds which move weather systems around the globe. Jet streams are found 9-16 km above the surface of the Earth, just below the tropopause, and can reach speeds of 200 mph.The position of a jet stream varies within the natural fluctuations of the environment. In this work the various physical parameters that are related to the jet formation and evolution such as thermal wind, potential vorticity and temperature variations at tropopause are analyzed. It has also been analyzed how the jet stream influences the air circulation and atmospheric patterns.
