Wind speed trends over the southwestern Atlantic Ocean, between 33° and 50°S

Surface scalar wind speed trends (from 1979 to 2009) at the southwestern Atlantic Ocean, between 33° and 50°S and 55° and 70°W, were estimated from the NCEP/NCAR I (NR1) and the Climate Forecast System Reanalysis (CFSR) using Sen's slope. Trends were tested using the seasonal Mann-Kendall test....
