Trop. Agric., 3. Energy load and instantaneous intensity of rainstorms at Samaru, Northem Nigeria / Kowal, J. M.
Titre de série : Trop. Agric., 3 Titre : Energy load and instantaneous intensity of rainstorms at Samaru, Northem Nigeria Type de document : texte imprimé Auteurs : Kowal, J. M. ; Kassam, A. H. Année de publication : 1976 ISBN/ISSN/EAN : CI-04513 Note générale : Using a specially designed instrument to give a continuous record of the number and size of raindrops on a time seale, the instantaneous intensity and energy load of tropical rains were assessed. Both the intensity and drop size of rains in the west African savanna are much greater than in temperate climates. The hig intensity of tropical storms is due to the lmarger size and greater nimber of raindrops falling per unit time. Because the predominant drp size of tropical rains is large, the energy load of storms is high. A high correlation between the average drop volume of rainfall and the amount of rainfall allows for a reliable and convenient estimate of the energy load of storms from the amount of rainfall. The seasonnal distribution of the energy load of rains in the west African savanna is similar to the annual distribution of rains.

Titre de série : Agricultural Meteorology, 12 Titre : A simple device for analusing the enrtgy load and intensity of rainstorms Type de document : texte imprimé Auteurs : Kowal, J. M. ; Kijewski, W. ; Kassam, A. H. Année de publication : 1973 ISBN/ISSN/EAN : CI-04512 Note générale : A simple apparatus is described for evaluating the energy load and intensity pf rainstorms relevant to studies of soil erosion and surface run-off. The instrument records graphically, on a time scale, the amplitude of electric pulses originating from the impact of raindrops on the surface of a tansducer dise, by making use of the piezo-electric effect. The size distribution of raindrops is calculated by analysing the graphic records of pulses on the chart from the number and the amplitude of pulses, and from the measured volume of total rainfall. The apparatus can be assembled using commercially available materials and recorders. It combines easy handling with acceptable accuracy.
