Sea-surface temperature, 2020 hurricanes , Colombian Caribbean, upwelling, La GuajiraAbstract
The Colombian Caribbean Sea had sustained surface water temperatures above 29 oC between July and December 2020. The geographic statistics calculated for the Colombian Caribbean Sea, examined from thermal images of that season in the upwelling area of La Guajira, showed that these values exceeded the monthly averages and the average for the hurricane season, and had not been previously observed. These temperatures occurred during the development of hurricanes Eta and Iota, which reached categories 4 and 5 as they passed through the San Andrés Archipelago and Central America. The review of the climatology indicates that this condition occurred at the inverse peak of the El Niño (La Niña) phenomenon. During this condition, the surface wind regime inverts as the Chocó jet arriving from the west strengthens.
