Índices de extremos de temperatura do ar na Amazônia brasileira

This paper aims to verify if there are changes in the trends of detection rates of climatic changes derived from the air temperature in 54 conventional meteorological stations (EMC’s) in the Brazilian Amazon. Employed databases from the daily series of maximum and minimum air temperature, with minim...
