Variability of extreme climate indices at Rio claro, São Paulo, Brazil

Variability of extreme climate indices at Rio claro, São Paulo, Brazil

Linear trends in climate extreme indices derived from precipitation and temperature data at the Rio Claro station, São Paulo-Brazil, are examined for the 40-year period 1966-2005 and the dataset is available at the Instituto de Pesquisas Meteorológicas (IPMET) of the State University of São Paulo (UNESP). The precipitation based climate indices did not show statistically significant trends. When correlated with the SST related indices in the Pacific and Atlantic Oceans, the analysis shows some weak but positive influence of El Niño and the TNAI (Tropical North Atlantic Index) over the rainfall behavior of the Rio Claro region. Overall, the temperatures are rising in the last 40 years with an indication of increasing the diurnal temperature range, especially in the recent past due to an increase in the maximum temperature.
