Les données collectées pendant trois ans ont servi à obtenir des modèles de ces distributions pour divers types de pluie : bruine, averse, pluie étendue, orage. La distribution lognormale constitue un bon ajustement pour tous les types de pluie en des lieux tropicaux, sauf pour la bruine où le modèle exponentiel convient. On discute aussi les conséquences de ces modèles pour des calculs de l’affaiblissement linéique dû aux pluies tropicales. The raindrop size distributions had been measured at three locations in Nigeria - Calabar, Ile-Ife and Zaria. The data collected over a period of three years have been utilized to obtain models of drop size distributions for drizzle, shower, widespread and thunderstorm rain. The lognormal distribution provides a good fit for all the rain types at these tropical locations except drizzle, where the exponential model is adequate. The implications of the models for specific attenuation calculations for tropical rain are discussed.
