The coldest place on the surface of the Earth broke its own record.
It turns out that the small valleys above the Antarctic ice cap recorded temperatures of -98 ° C, five degrees lower than the estimate so far, according to one study published in the scientific journal Geophysical Research Letters.
Scientists announced in 2013 the discovery of the site with the lowest temperatures on Earth, thanks to the launch of several satellites. Observation of the planet
This was from several points of the eastern Antarctic plateau [19659005] a region where snow is abundant, where the south pole is also and where temperatures of -93 ° C have been recorded.
But now researchers have used new data to conclude that the temperatures are even lower and that they are observed during the night of the South Pole, mainly in the jungle. ulio and august
How is this possible?
In the previous study, the experts explain the conditions necessary for the temperatures to fall dramatically as well.
And they came to the conclusion that light winds and clear skies are not the only key factor; also plays a crucial role extremely dry winds, which must be maintained for several days.
To achieve the new results, the experts observed small depressions or shallow holes in the Antarctic Ice Sheet, where cold, dense, and descending air accumulates on the surface and can remain there for several days
so that the surface and air above cool down even more, until clear, calm and dry conditions are broken down and Air is mixed with warmer air in the atmosphere.
"In this area we see incredibly dry air periods, allowing the heat of the snow surface to be" Ted Scambos, lead author of the study, explains in a statement

The new record at -98 ° C could be beat again if the conditions Scientists have remained constant for several weeks, although Scambos considers that is very unlikely
In case this happens, the team of researchers is already working on designing the instruments that allow them to survive and work in even colder places. air and snow
The experts expect these means of work to be ready for two years from now
