Abstract : The report is a preliminary analysis of digitized satellite cloud brightness data that will be used in developing a model for large-scale analysis over data-void tropical areas, which is based on Wallace's (1971) postulation that such data may be used to estimate vertical motion in the tropics. The relationship between satellite cloud brightness and large-scale 200 mb divergence on 5 degrees x 5 degrees grids in the tropical western North Pacific is examined from several angles. Correlation coefficients between the two fields are computed on a daily basis for the region of study and at each grid point for 8-month time series. (Modified author abstract)
