Summary
[edit]DescriptionPatagonia Heatwave — Argentina, Chile (patagonia-heatwave-argentina-chile).jpg |
English: A strong heatwave is affecting Patagonia and the Antarctic Peninsula in the second week of February, with temperatures 10°C higher than average values of the period. In Punta Arenas, one of the major cities in the southern Chilean Patagonia, temperature has risen up to 25°, while the typical maximum value is about 15°C. According to the experts of the Dirección Meteorológica de Chile (DMC), this phenomenon is due to high pressure that allows the influx of warm subtropical air. Heatwaves are not unusual events in Patagonia, but their frequency is increasing every year. 2020 had been characterised by a lower number of heatwaves in the region, due to the presence of La Niña, but models suggest a new increase for the summer of 2021. These high temperatures result from a complex climatic situation, and they are mainly a consequence of the global warming according to climatologists from the University of Chile. This image shows the Land Surface Temperature (LST) map over Patagonia as recorded by the two Copernicus Sentinel-3 Satellites on 11 February 2021 LST is the temperature of the soil and should not be confused with the air temperature at ground level. This is why it is not possible to measure the temperature of the soil in areas covered by clouds. The Copernicus Sentinel-3 mission is composed of two twin satellite (Sentinel-3A and Sentinel-3B) that are both equipped with the Sentinel-3 Sea and Land Surface Temperature Radiometer, an instrument whose main objective is to provide global and regional Sea and Land Surface Temperature (SST, LST) with a very high level of accuracy (for both climatological and meteorological applications). |
