Neural models may be very precise but, being numerical, provide only limited contribution to the understanding of the phenomenological process, contrary to phenomenological models. In this paper we use neural techniques to evaluate and to provide information on the sub-models that composes a phenomenological model. We also show how some hybrid(More)
This paper deals with an investigation of dynamic characteristics of rainfall rate in the Amazon Region. Experimental data from 3 (three) selected locations pertaining to different climate subtypes identified in this tropical rainy region constitute the basis of the analysis carried out here. Details about the annual clock hourly rainfall accumulation and(More)
Based on rain gauge and radar measurements this paper discusses the variability of the spatial distribution of precipitation in the Amazon region. Regarding the horizontal behaviour, the emphasis is given to the dimension and statistical characteristics of rain cells. On the other hand, the problem associated to the vertical extent of rain is stressed with(More)
