Atmospheric Motion Vector (AMV)
Outline
Atmospheric motion over a wide area can be derived by tracing the movement
of individual cloud or water vapor patterns in successive MTSAT images.
This product is called Atmospheric Motion Vector (AMV), and also includes
information on wind speed and direction.
At the MSC, AMVs are derived every hour over the Northern Hemisphere and
four times a day over the Southern Hemisphere. Derived wind data are disseminated
to National Meteorological and Hydrological Services (NMHSs). AMVs are
useful for numerical weather prediction, especially over ocean areas where
other wind observations are very sparse.
