“…This area of the Coastal Lowlands of the State presents low PRCPTOT, but it can be concentrated in short periods, especially during austral spring and summer. Even in the face of extreme precipitation values in a single day, given by the RX1day indicator, high rainfall often occurs in a few hours, causing inconveniences such as floods and overflowing rivers, especially in large cities such as Rio de Janeiro (Armond and Neto 2019 ). This fact means that the climatological values of 110 mm for RX1day in the Metropolitan Region of Rio de Janeiro are usually recorded in 2 or 3 h by heavy precipitation (Fig.…”

This paper presents a synthesis of the main characteristics of precipitation in the State of Rio de Janeiro (Brazil) based on extreme rainfall indicators. Daily precipitation data are derived from 56 rainfall stations during the second half of the twentieth century and the 2000s. Eight indices related to extreme precipitation were analyzed. The Mann–Kendall nonparametric test and the Sen's Curvature were employed to evaluate the significance and magnitude of trends. The primary climatological aspects and identified trends throughout the last decades are discussed, besides the hydrometeorological impacts associated with them. Lower values of annual total precipitation are recorded in northern Rio de Janeiro (around 800 mm) and higher in the southern State (up to 2,200 mm). The Serra do Mar affects the frequency of heavy precipitation, and the areas near the sea and high relief present the highest values of consecutive days with expressive rainfall (more than 150 mm in 5 days). These areas also showed a high concentration of flood and landslides events. Most of Rio de Janeiro exhibits precipitation intensity of about 13 mm/day. The maximum number of consecutive dry days shows a gradient from the coast (about 30 days) to the State's interior (around 50 days). Regarding trends, there is a growth of accumulated extreme precipitation in various stations near the ocean. The extreme rainfall in 24 h displays an increase in most Rio de Janeiro (+ 1 to + 5 mm/decade). The consecutive dry and rainy days present similar signs of decreasing trends, suggesting irregularly distributed precipitation in the State. This study is especially relevant for decision-makers who need detailed information in the short and long term to prevent natural hazards like floods and landslides and the related impacts in the environmental and socioeconomic sectors of the Rio de Janeiro.

“…Este apartado del libro parte con el manuscrito The urban climate system and the impacts of flooding on Rio de Janeiro, Brazil (Armond & Sant'Anna Neto, 2019). Esta contribución analiza la relación espacial entre sociedad y naturaleza, con las diferentes morfologías urbanas, y como ello genera diferentes climas urbanos.…”

Presentamos el reciente libro Urban Climates in Latin America, editado por la prestigiosa editorial internacional Springer. Este libro viene desde América Latina a aportar al conocimiento de los climas urbanos con una mirada desde el Sur, donde la producción en estos temas ha sido relativamente nueva, pero con bastante energía desde la disciplina geográfica. Además, el libro ha sido editado por dos geógrafos y doctores especialistas en climatología, como son el profesor Hugo Romero Aravena y el profesor Cristián Henríquez. El libro, tal como revela su lectura, tuvo su génesis en 2015, durante la novena conferencia internacional sobre climatología urbana (9th International Conference on Urban Climate-ICUC) celebrada en Toulouse (Francia) y duodécimo Simposio sobre medio ambiente urbano de MeteoFrance (2th Symposium on the Urban Environment). Ello es relevante, pues hablamos en el primer caso de la principal conferencia mundial sobre climatología urbana. El libro se estructura en 15 capítulos, la introducción y luego 14 capítulos, los cuales a su vez se agrupan en tres partes. La primera parte titulada Urban Heat Islands, Local Climate Zones and Thermal Comfort, la segunda Air Pollution and Urban Climates y finalmente Climate Disasters, Healh, and Urban Resilience. Ya al observar las partes del libro notamos el énfasis de la investigación latinoamericana en temas tan fundamentales como: las islas de calor urbana (Manley, 1958), confort térmico (Mayer & Höppe, 1987) y zonas climáticas locales (Stewart & Oke, 2012); la importancia de la calidad del aire urbano y su relación con el arbolado y los desafíos de la sustentabilidad de las ciudades (
