Vertically integrated diabatic heating rate estimates (H) calculated from 32 months of European Centre for Medium-Range Weather Forecasts daily analyses (May 1985-December 1987) are determined as residuals of the thermodyanmic equation in pressure coordinates. Values for Global, distribution of H is compared with previous results and with outgoing longwave radiation (OLR) measurements. The most significant negative correlations between H and OLR occur for (1) tropical and northern hemisphere mid-latitude oceanic areas and for (2) zonal and hemispheric mean values for periods less than 90 days. Largest positive correlations are seen in periods greater than 90 days for the northern hemispheric mean and continental areas of North Africa, North America, northern Asia, and Antarctica. The physical basis for these relationships is discussed. An interyear comparison between 1986 and 1987 reveals the El Nino-Southern Oscillation signal.
