Description
Summary:The aim of this study was to analyze trends in precipitation and temperature on Trindade Island, South Atlantic Ocean. Time series from 1984 to 2008 for precipitation and from 1958 to 2008 for air temperature were analyzed. The regression analysis and Mann-Kendall test were used to test the trend in annual and seasonal scale of precipitation – January, April, July and October, which represents the middle months of summer, autumn, winter and spring, respectively, as well as for maximum and minimum air temperature. Results indicated that for precipitation time series there was no significant trend, while for minimum air temperature there was a significant trend to decay. In addition, no significant trend was found for maximum air temperature.
