Observed trends in indices of daily temperature extremes in South America 1960-2000
A workshop on enhancing climate change indices in South America was held in Maceió, Brazil, in August 2004. Scientists from eight southern countries brought daily climatological data from their region for a meticulous assessment of data quality and homogeneity, and for the preparation of climate cha...

This study presents an examination of the trends over 1960-2000 in the indices of daily temperature extremes. The results indicate no consistent changes in the indices based on daily maximum temperature while significant trends were found in the indices based on daily minimum temperature. Significant increasing trends in the percentage of warm nights and decreasing trends in the percentage of cold nights were observed at many stations. It seems that this warming is mostly due to more warm nights and fewer cold nights during the summer (December-February) and fall (March-May). The stations with significant trends appear to be located closer to the west and east coasts of South America. © 2005 American Meteorological Society. Fil:Barros, V.R. Universidad de Buenos Aires.
