An attempt is made to investigate the relationship between the digitized satellite brightness data and the kinematically computed 200-mb divergence in the tropical western North Pacific during the period 19 April-20 December 1971. Both spectral and correlation analyses techniques are used. The power spectra of the two fields reveal two dominant period bands one centered at approximately 10 days and the other at approximately 5 days. Horizontal structures, as shown in the inter-longitudinal cross-spectra in the two bands, suggest that brightness is more organized than divergence, although the two fields resemble well each other whenever an organized divergence pattern is observed.
