In the agricultural area, many studies related to precipitation have tried to evaluate the effects resulting from its occurrence in surface runoff. In this case the knowledge of not only the information relative to precipitation, its duration and intensity of the rains, but, also the profile of the precipitation is of great importance. With this objective, the present work was carried out to develop a model called CLIMABR, for the generation of synthetic precipitation series and of the instantaneous profile associated to these for the climatic conditions of the State of Rio de Janeiro. Pluviometric and pluviographic data from eleven stations of the Fundação Superintendência Estadual de Rios e Lagoas - SERLA and of Companhia LIGHT - Serviços de Eletricidade S.A. were utilized. In the generated synthetic series, the number of rainy days were obtained, according to the probabilities associated to the Markov chain and the total daily precipitation. The comparison of the data generated by CLIMABR with the observed data showed a good performance of the model for the estimation of these variables.
