Análise rítmica em climatologia aplicada a eventos extremos de precipitação no município do Recife - PE.

Abstract

Investigating extreme precipitation events has become essential in the current context of climate behavior changes triggered by anthropogenic activities, which often occur in a predatory manner and disregard the limits the planet can withstand. Extreme precipitation events pose potential risks of material and human losses. Accordingly, extreme precipitation events occurring in the municipality of Recife were analyzed, establishing a historical series from 1994 to 2023. This investigation, grounded in the Rhythmic Analysis technique, primarily aimed to analyze climate dynamics by examining the variation in the rhythm of climate elements and extreme precipitation events in Recife-PE. Data used in this study were gathered from climate research and monitoring institutions, including the Pernambuco Water and Climate Agency (APAC), the National Institute for Space Research (INPE), and the National Institute of Meteorology (INMET). The results showed that the standard habitual period (2006) was marked by the influence of the Tropical Atlantic Air Mass, the Intertropical Convergence Zone, and the Breeze System. The rainy standard period (2011) highlighted the predominant influence of the Equatorial Atlantic Air Mass, as well as the Eastern Wave Disturbances and the ITCZ, which contributed to the substantial rainfall amounts received by the municipality in the analyzed months. In the dry standard period (2018), the Equatorial Atlantic and Tropical Atlantic Air Masses and the Eastern Wave Disturbances were also predominant. The application of Rhythmic Analysis proved to be an important tool for analyzing climate dynamics and the spatiotemporal variation of meteorological components impacting the municipality of Recife.
