Aplicação da análise rítmica na interpretação de extremos de chuva em janeiro de 2020 em Belo Horizonte - MG

Abstract

Extreme rain events can be characterized by the occurrence of high totals in a short period of time, and the impacts are often amplified negatively by changes introduced in the environment (changes in the hydrological network, unavailability of green areas, etc.). Using as an example the episodes of concentrated rain in January 2020 in Belo Horizonte (Minas Gerais - Brazil), the objective of this article was to apply the "rhythmic analysis" to understand the relationship between atmospheric dynamics and the rainfall impact produced in the city . The data were obtained from local meteorological stations from the official INMET network and from information transmitted over the internet. The results reinforced the need to consider deviations in variations of this attribute and the adoption of preventive measures.
