Sea surface temperature (SST) and rainfall erosivity in the Upper Grande River Basin, southeast Brazil

Abstract: Relationships between regional climates and oceanic and atmospheric anomalies are important in understanding the rainfall regime of a given region. This work aimed to analyze rainfall erosivity in the Upper Grande River Basin, Southern Minas Gerais State, Brazil; namely the two most representative environments, the Mantiqueira Range (MR) and the Plateau of Campos das Vertentes (PCV). These areas can be affected by the El Niño Southern Oscillation (ENSO) phenomena, which can be evaluated by indicators such as S… Show more

“…É constituída por zonas fisiográficas importantes do ponto de vista de "produção de água", notadamente, Campo das Vertentes e Serra da Mantiqueira. O clima é do tipo Cwa em grande parte da bacia e Cwb na sua cabeceira, conforme Köppen (Mello et al, 2012). Seu relevo é ondulado, apresentando declividade superior a 15 % em aproximadamente 90 % da área da bacia.…”

“…According to Mello et al (2012), the region presents an average annual rainfall of 2100 mm, with predominance of the Cwb climatic type, as classified by Köppen. The average annual temperature is 18° C, with the average minimum under 11° C in the winter (from May to September) and average maximum 21° C in the summer (from November to March).…”

“…According to Mello et al (2012), local climate is super-humid by the Thornthwaite classification, meaning a highly positive water balance during the whole year. Alternatively, local climate can be classified as Cwb (rainy temperate or altitude subtropical) type by the Köppen classification, with cool winters, with lesser rainfall than the summer.…”

“…Soil organic matter (SOM) contents under native forest are high at the 0-20 cm depth, and pH is accordingly very low (Table 1). Such conditions are favored by local high precipitation (~2,000 mm per year) and mildly cool temperatures, even during the summer (Mello et al, 2012). There were losses of ~50% and of ~28% of SOM contents at the 0-20 and 20-50 cm depths, respectively, upon land use change to pasture.…”
