Topical Collection on the International Conference of Marine Science ICMS2018, the 3rd Latin American Symposium on Water Waves (LatWaves 2018), Medellin, Colombia, 19-23 November 2018 and the XVIII National Seminar on Marine Sciences and Technologies (SENALMAR), Barranquilla, Colombia 22-25 October 2019


In order to look for climatological changes on significant wave height and wind magnitude distributions, two decades of altimeter data were analyzed in a monthly 1° × 1° grid at the Southeastern Pacific Ocean, offshore of Chile. Both wind magnitude and significant wave height shown significant growing medians, at a rate of up to 0.2 m dec−1 and 1 m s−1 dec−1, respectively. Nevertheless, the shape of both statistical distributions shows regional differences from North to South. We conclude that both significant wave height and wind magnitude distributions experienced significant changes during the last two decades and also that their behavior is not uniform along the Southeastern Pacific Ocean.
