| Popis: | Turbulent fluxes of heat and moisture measured during the GARP Tropical Atlantic Experiment of 1974 (GATE) are analyzed with respect to magnitude, distribution with height, intercorrelation and relation to synoptic weather systems. Sensible heat transport on the average is small, whereas latent heat transport is large and nearly always directed upward. In and near convective cloud masses both fluxes become very large compared to clear air, especially sensible heat transfer. A qualitative model of cold and warm downdrafts is presented. There are not only warm, moist updrafts, but also warm, dry downdrafts sinking against buoyancy so that sensible heat fluxes up and down nearly cancel. The role of enhanced fluxes in the general circulation is discussed. DOI: 10.1111/j.2153-3490.1978.tb00869.x |
