Delineation of Precipitation Areas Using Meteosat Infrared and Visible Data in the Region of the United Kingdom

摘要: Abstract The relationship between precipitation and infrared visible satellite data is investigated in the vicinity of United Kingdom. investigation uses histograms Meteosat data, built up from many half-hourly fields, which represent frequency distribution pixels as a function temperature brightness. Separate are produced for classified “precipitation” “no precipitation” by coincident radar observations. study conducted separately four distinct synoptic types: cold fronts, warm cold-air convection, mesoscale convective systems (MCSs). A method presented that this information to delineate areas precipitation. It found use combined yields better results than using alone all types date majority. Use itself, except warm-front cases. r...
