Key message This paper aims to provide evidences of the influence of physical atmospheric parameters on the growth of the endemic tree Schinopsis brasiliensis, and their consequent teleconnection with large-scale modes of climate variability affecting rainfall in semi-arid region of the Brazilian Northeast. Abstract The Brazilian Northeast is a region of low rainfall and high temperatures and evaporation...
A tree-ring width chronology was developed from samples of thirteen Poincianella pyramidalis trees from the Caatinga semiarid region of northeastern Brazil, where the climate is characterized by marked seasonality in precipitation levels.
