Chart created in MetX showing the Jet Stream on the 300 hPa level with wind barbs based on u and v wind components:
This parameter denotes the vertical wind shear between 850 hPa and 200 hPa and describes how the wind changes with height. The vertical wind shear is often used to assess favorbale environmental conditions for tropical cyclone formation and thunderstorm development.
