Analyses of maximum precipitation in Brazil and the variability of diurnal cycle
Published: 16 March 2023 by MDPI in The 7th International Electronic Conference on Water Sciences session Hydrological Extremes, Hazards and Disasters
According to recent works, the diurnal cycle is more geographically pronounced in places such as South America, and this analysis aims to observe how climate variability is associated with meteorological phenomena at different scales. For this, a set of hourly data from rain gauges throughout Brazil was collected, and through 411 automatic rain gauges, the data were selected between January 1, 2008, and December 31, 2020. clustered multivariate statistics were performed for regional characterization of the data, with sets of 4, 5, and 6 groups. The identification of the occurrence of different daily cycles on the sub-daily scale demonstrates intense rainfall associated with different meteorological phenomena and spatial variations.
