They are produced by tracking clouds or gradients in water vapour through successive satellite images. AMVs have been assimilated in forecast models since the 1980s. Traditionally they are generated using imagery from geostationary satellites, which monitor a constant region of the Earth. AMVs are produced at several centres including EUMETSAT in Europe, NESDIS in the USA, JMA in Japan, CMA in China and IMD in India.Full Disk from 105 degrees E-copyrightcopyrightCMA-AMV2009-03-2355.0 -50.0155.0 50.0
