Resumo: The intense rainfall is characterized by its peculiarly irregular temporal and spatial distribution. A maximum recorded during a 24-hour interval starting at any time will be set to a 24-hour maximum. It should not be confused with the 1-day classification which refers to the maximum classification observed in 1 day, always collected at the same time, considered here from 9:00 am to 9:00 am the following day. The objective of this work is to determine intense rainfall disaggregation constants for the state of Bahia from 19 historical rainfall series, comparing them with the coefficients obtained for other regions of Brazil. For modeling the frequency of heavy rains of different durations, the probability distribution was used. To determine the disaggregation constants, the duration relations method is used. This method consists of two aspects: a) the tendency of the probability curves of different durations to remain parallel to each other; and b) for different locations, there is a great similarity in the relationships between maximum mean precipitations of relationships. The following mean disaggregation constants for the state of Bahia were selected: h10min/h30min = 0.48; h20min/h30min = 0.79; h30min/h1h = 0.74; h40min/h1h = 0.87; h50min/h1h = 0.94; h1h/h24h = 0.59; h2h/h24h = 0.69; h3h/h24h = 0.76; h4h/h24h = 0.80; h6h/h24h = 0.85 e h12h/h24h = 0.92. Such constants are an important tool for applications that demand the estimation of intense rains of duration in the state of Bahia.

Un máximo registrado durante un intervalo de 24 horas que comienza en cualquier momento se establecerá en un máximo de 24 horas. No debe confundirse con la clasificación de 1 día que se refiere a la clasificación máxima observada en 1 día, recolectada siempre a la misma hora, considerada aquí de 9:00 am a 9:00 am del día siguiente. El objetivo de este trabajo es determinar las constantes de desagregación de lluvias intensas para el estado de Bahía a partir de 19 series históricas de lluvias, comparándolas con los coeficientes obtenidos para otras regiones de Brasil. Para modelar la frecuencia de lluvias intensas de diferentes duraciones, se utilizó la distribución de probabilidad. Para determinar las constantes de desagregación se utiliza el método de relaciones de duración. Este método consta de dos aspectos: a) la tendencia de las curvas de probabilidad de diferentes duraciones a permanecer paralelas entre sí; y b) para diferentes ubicaciones, existe una gran similitud en las relaciones entre las precipitaciones medias máximas de relaciones. Se seleccionaron las siguientes constantes medias de desagregación para el estado de Bahía: h10min / h30min = 0,48; h20 min / h30 min = 0,79; h30 min / h1 h = 0,74; h40 min / h1 h = 0,87; h50 min / h1 h = 0,94; h1 h / h24 h = 0,59; h2 h / h24 h = 0,69; h3 h / h24 h = 0,76; h4h / h24h = 0,80; h6h / h24h = 0,85 y h12h / h24h = 0,92. Tales constantes son una herramienta importante para aplicaciones que demandan la estimación de lluvias intensas de duración en el estado de Bahía.As chuvas intensas são caracterizadas por sua distribuição temporal e espacial peculiarmente irregular. A precipitação máxima registrada durante um intervalo de 24 horas, iniciando a qualquer momento, será definida como precipitação máxima de 24 horas. Não deve ser confundida com a precipitação de 1 dia que se refere à precipitação máxima observada em 1 dia, sempre coletada no mesmo horário, considerada aqui das 9h às 9h do dia seguinte.

Para a determinação das constantes de desagregação, utiliza-se o método das relações de durações.
