SESSION I CURRENT SYSTEMS TO DERIVE ATMOSPHERIC MOTION VECTORS (AMVs)
ثبت نشده
چکیده
Session I contained seven presentations, which described the status of systems, used in the production of Atmospheric Motion Vectors (AMVs). Each of the major production centres described present and future plans. A common thread in many of the presentations was the emerging production of high-density winds. The use of high density winds and improvements in quality control procedures portend a major impact at the numerical weather prediction centres where preliminary tests already indicate improvements in forecast skill.

Derivation of Mesoscale Atmospheric Motion Vectors Using Coms Images at Kma/nimr
Communication, Ocean and Meteorological Satellite (COMS) is the first Korean geostationary satellite, which is located in 128.2°E launched in 2010, and it is currently under normal operation. Atmospheric motion vectors (AMVs) derived with high resolution satellite images are useful for analyzing mesoscale motion such as convective clouds and ageostrophic flow. National Institute of Meteorologic...

The advent of the Meteosat Second Generation (MSG) provides many new opportunities for improved derivation of Atmospheric Motion Vectors (AMVs) from geostationary satellite data. MSG will provide full field of view imagery data every 15 min. with a sampling distance of 3 km, already improving the capabilities to derive AMVs. Another main improvement is the large range of available channels that...

In order to examine the effectiveness of the NSMC scheme, a comparison was arranged under the cooperation frame between EUMETSAT and CMA (China Meteorological Administration). Two periods of data from Meteosat-5 including IR and WV channels were processed and compared by both the EUMETSAT and NSMC schemes. The comparison periods were one week long each, and in January and July respectively. The...
