Chuvas máximas de 24 horas em Belém, probabilidade de ocorrência e tempo de retorno.
Rainfall characteristics such as seasonality and variability and occurrence of maximum 24-hour rainfalls are of great importance for the effectiveness of rainfall for agriculture, water balance and soil erosion. In order to analyse these rainfall characteristics to Belem where in general there is no dry season, various rainfall aspects were studied including: rainfall seasonality, observed and theoretical frequency distribution and recurrence interval for 24-hour rainfalls of a 30-year period. The degree of concentration of the largest rainfall events of each year on each month and the rainfall intensities within the observed largest storm were also analysed. The mean results indicated that although in Belém where annual totals usually exceed 3000mm, there is only a probability of 3 percent that annual-maximum 24-hour rainfall at Belem will equal or exceed 136mm, and that such event would be referred to as the 30-year, 24- hour rainfall
