Abstract : Digitized cloud brightness data for July 1969 are examined to determine the degree of relationship between organized brightness patterns and the large-scale convection field in the tropical western North Pacific. Correlation coefficients between kinematically computed vertical motion fields and cloud brightness are generally low, except for a few notable days. Examination of time-longitude sections reveals a close association between propagating brightness patterns and vertical motion fields, indicating that the former are reflections of synoptic wave passages, rather than simply inactive clouds advected by zonal flow. In view of the potential usefulness of such satellite data, a technique is proposed that uses satellite cloud data to objectively determine the large-scale tropical flow. (Modified author abstract)
