Abstract
The wide band high resolution radiometer on the NIMBUS 7 satellite provides a detailed view of the net outgoing long wave radiation around the 11.5μm band. The availability of this data during 1979 made it possible to explore a statistical relationship among the radiance data and the divergent circulations based on the 200mb wind from the analysis of the Global Experiment data sets. This study reveals a very strong relationship between these fields at a horizontal resolution of wave number 8 (two dimensional). Examples of the monthly averaged and daily maps of the divergent wind, observational and statistically derived at this resolution, are compared. The use of this relationship, especially over the data sparse tropical latitudes, for numerical weather prediction and climate studies is suggested.
