Antarctic declared extremely low temperature



The coldest place on Earth has not surprisingly been found in the Antarctic, but it has become colder than previously thought.

This has led researchers to investigate how low surface temperatures can reach this planet. The coldest spot on Earth is on the East Antarctic Plateau between Dome Argus and Dome Fuji.

According to a new analysis published in Geophysical Research Letters temperatures dropped to -148 degrees Fahrenheit or -100 degrees Celsius, a new mark for the coldest temperature anywhere in the world

The situation in the Antarctic

The results were even colder than the analysis of satellite data in 201

3, which was only -135 degrees F or -93 degrees C in the region.

The new study analyzed satellite data collected during the winter of the Southern Hemisphere from 2004 to 2016, with the dataset updated to reflect updated weather station measurements.

Antarctica receives very little direct sunlight and is surprisingly high, with a portion positioned about 14,000 feet above sea level. The higher the value, the lower the atmospheric pressure and the more heat energy is distributed, as explained by IFL Science.

Ice also has an extremely high reflectivity and melts very little with the evaporation taking place there. All these factors ensure that parts of the Antarctic will easily be the coldest parts of the earth.

Is there a limit to how cold it can get?

It is interesting to note that although the coldest areas in the area were scattered hundreds of kilometers, the lowest temperature was practically the same. The authors asked themselves: is this a limit to the cold on the plateau?

The team found that air temperatures were -137 degrees F in the coldest places that did not have weather stations. From the difference between satellite measurements of the lowest snow temperatures at the station Vostok and three automated and the air temperatures at the same time and at the same place, the conclusion was drawn.

"In this area, we see periods of incredibly dry air, and this allows the heat from the snow surface to shine more easily into space," Dr. Ted Scambos, study author and senior researcher at the National Snow and Ice Data Center of the University of Colorado Boulder.

DR. Scambos added that record lows are about as cool as possible on the earth's surface. Such levels can only be achieved if a clear sky persists together with dry air for a few days.

While the temperature might drop a little more if such conditions persist for a few weeks, they are unlikely to occur.
