The coldest place on Earth is unsurprisingly found in Antarctica, but it has become colder than previously suggested.
This led the researchers to probe how low surface temperature can get on this planet. The coldest point of the Earth is located on the East Antarctic Plateau, located between Dome Argus and Dome Fuji.
According to a new analysis published in Geophysical Research Letters temperatures go down to -148 degrees Fahrenheit or -100 degrees Celsius, a new mark for the coldest temperature ever recorded in the world.
The Antarctica Situation
The results were even colder than what an analysis of satellite data revealed in 2013, which was as low as -135 degrees F or -93 degrees C.
The New The study analyzed satellite data collected during the winter of the southern hemisphere from 2004 to 2016, with the dataset updated to reflect measurements updated by meteorological stations.
very little direct sunlight and is positioned surprisingly high, with a portion about 14,000 feet above sea level. The higher the atmospheric pressure, the lower the atmospheric pressure and the lower the temperature. Thermal energy is dispersed, as IFL Science explains
Ice also has an extremely high reflectivity and very little melting with evaporation. All of these factors ensure that parts of Antarctica will easily be the coldest spots on Earth.
Is there a limit to the cold?
It is interesting to note that even though the coldest sites in the region were scattered kilometers, the lowest temperature was practically the same. The authors wondered: does this set a certain limit to the cold on the set?
The team found that the air temperatures at the coldest sites, with no weather stations, were -137 degrees F or -94 degrees C. The inference was made from the difference between the satellite measurements of the lowest surface temperatures at the Vostok station and three automatic temperatures, and the air temperatures at the same time and at the same place. Incredibly dry air, and this allows the heat of the snow surface to radiate more easily in the space, "said Dr. Ted Scambos, author of the study and principal investigator at Boulder National Snow and Ice Data Center. Dr. Scambos added that record lows are about as cold as possible on the surface of the Earth. Such levels can only be reached when clear skies and dry air persist for a few days.
Although the temperature may drop a little more if such conditions persist for a few weeks, this is unlikely to happen.
