GOES-West Full Disk - Derived Motion Winds

Derived Motion Winds key:

Red barbs: High level winds: 100 - 400mb, altitude approximately 23,000 - 46,000 ft. (7-14 km)

Cyan barbs: Mid-level winds: 400 - 700mb, altitude: approximately 10,000 - 23,000 ft. (3 - 7 km)

Yellow barbs: Low-level winds: > 700mb, altitude: approximately < 10,000 ft. (< 3 km)

Derived Motion Wind Vectors (DMW) are produced using sequential ABI images and as such they can provide important information about winds at different levels during asynoptic times. Areas of wind shear or jet maxima can be identified. Wind Vectors are computed using both visible and infrared (including water vapor) imagery. DMWs are used to identify regions of strong winds or wind shear to confirm model forecasts and/or to anticipate the result of strong winds or shear.
