Short summary
Satellite wind data were used to understand surface wind variability in the eastern austral Pacific Ocean, a region dominated generally by strong westerlies, but the empirical orthogonal function demonstrated that wind variability was dominated by a synoptic scale. Nighttime heatwave events were detected to produce air temperature maxima which exceeded the normal midday maxima caused by solar radiation. Downwelling conditions prevailed in the study region due to onshore Ekman transport.
