Large-Scale Precipitation and Outgoing Longwave Radiation from INSAT-1B during the 1986 Southwest Monsoon Season

摘要: Abstract Areally averaged precipitation and broadband outgoing longwave radiation (OLR) have been estimated from infrared window channel observations INSAT-1B, the Indian geostationary satellite, for period June–September 1986. The estimation techniques used were identical with those contained in previously published work using GOES (for precipitation) NOAA OLR) satellite data. fields of monthly mean OLR are quite similar, regions low flux corresponding to arm heavy precipitation. Two bands rainfall found, one near equator, possibly associated Intertropical Convergence Zone, another extending northwestward Indonesia through Bay Bengal over India. This latter feature exhibited a pronounced southeastward retreat during course season. estimates reasonably consistent both distribution magnitude India climatological derived rain gauge measurem...
