Where Was The Lowest Temperature Ever Recorded - New satellite-based research found a new record low temperature anywhere on Earth: a super cold -144°F (-98°C), significantly exceeding all previous measurements.
No specific date could be pinpointed for the record low, measured on the East Antarctic Plateau, which includes the South Pole, but was based on analysis of data collected by satellites between 2004 and 2016 to show that this low temperature always occurs when the conditions are right. .

It surpassed the previous lowest land temperature recorded on July 23, 1983 by a ground station at Vostok Station in Antarctica. It also surpassed the previous satellite-based estimate of -135°F obtained in 2013 using a similar approach.
Scientists Detect Coldest Temperature Ever Recorded On Earth's Surface
In an article in Geophysical Research Letters, multi-institutional researchers led by Ted Scambos, senior scientist at the University of Colorado-Boulder's National Snow and Ice Data Center, found that under the right conditions, temperatures fall much more than previously expected . Day with exceptionally clear skies, light winds and very dry air.
A few miles above sea level (about 3,500 m) on the ice sheet covering the East Antarctic Plateau — actually near the Vostok Station measurement — the temperature is typically below -130 °F (-90 °C). ). However, pockets of very dense, very cold air sink down and become trapped in small troughs only 6 to 9 feet deep. This very low air temperature allows the snow in these cavities to radiate even more heat, resulting in extremely low ground temperatures.
This new research combined data from several NASA satellites, including one that was recalibrated in 2016, with new information from ground stations.
Researchers assume that with clear skies it would take weeks, not days, for the air temperature to drop further and for the snow to cool even further in these low-pressure areas.

However, they have developed new ground-based measuring devices that can withstand extreme cold and which they plan to use in the next two years.

In 2013, scientists announced that they had discovered the lowest temperature ever recorded on Earth's surface. That temperature -- minus 93 degrees Celsius (minus 135 degrees Fahrenheit) -- has been observed at several locations on the East Antarctic Plateau, a snow-capped plateau that encompasses the South Pole.
Now, after re-examining weather records for the region, the same researchers have found that temperatures in some areas did indeed drop lower than previously thought between 2004 and 2016, in several cases to a record minus 98 degrees Celsius (minus 144 degrees Celsius). Fahrenheit). .
Are You Closer To The Hottest Or The Coldest Place Ever Recorded?
The findings, to be published in the journal Geophysical Research Letters, could change scientists' understanding of how low temperatures can reach the Earth's surface.
For the study, a team led by Ted Scambos of the University of Colorado Boulder's National Snow and Ice Data Center reanalyzed temperature data for the East Antarctic Plateau collected during the southern hemisphere winter between 2004 and 2016.
This was the same data set that the researchers examined in 2013, which resulted in the previous record low. However, it has since been updated to include more recent weather station readings and give the team a better idea of the true surface temperature.
The updated information showed that the record low was about 5 degrees Celsius (9 degrees Fahrenheit) colder than the temperature they reported in 2013. The coldest of these temperature readings were taken in small cavities two to three meters deep during the polar night. covering the Antarctic Ice Sheet. According to the researchers, these ice collapses can trap super-cold, dry air.

When the team made their first findings in 2013, they suggested that persistently clear skies and light winds were needed for temperatures to drop that low. However, the new results show that the air must also be extremely dry, since water vapor traps heat in the air.
In 2013, scientists announced they had found the coldest spot on Earth - measured at multiple points on the East Antarctic Plateau. But new measurements have shown that it is even colder in the area than originally thought. Ted Scambos/University of Colorado Boulder
Then, for the mercury to reach minus 98, all of these conditions must last for several days. In order to sink, they would have to stop for several weeks, which scientists say is extremely unlikely.
Because once the temperature falls below a certain level, the air cools so slowly that it cannot get much colder before the weather conditions inevitably change. Against this background, Scambos suspects that minus 98 degrees Celsius is probably as cold as the earth's surface will ever get.

"There's a limit to how long conditions allow you to cool to these extremely low temperatures, and a limit to how much heat you can shed into the atmosphere, because water vapor has to be almost non-existent to shed at those." Temperatures conduct heat away from the surface," Scambos said in a statement.
The president said he remains committed to "growing the economy from the middle down, not top down." .
Amazingly, 88 below low isn't even the record low in this remote, diamond-rich Russian region of Yakutia, which is part of Siberia.
Residents there were drawn to the cold, as evidenced by images of cold-weather selfies on social media and stories of stunts performed in extreme temperatures, the Associated Press said. Women posted photos with frozen eyelashes, while Yakutia Media published a photo of Chinese students undressing to bathe in a hot spring.

The cold had serious consequences. Over the weekend, two men froze to death trying to walk to a nearby farm after a car broke down. And although students regularly go to school when the temperature is below 40 degrees, classes were canceled across the region this week.
By and large, however, bitter temperatures did not bother the hardy residents of Oymyakon (population 500), some 5,300 kilometers east of Moscow. Local officials said Tuesday all homes and businesses in the area have working central heating and access to backup generators.
Although the official temperature on Tuesday was "only" 74 degrees below zero, some residents recorded temperatures in their homes as high as 88 degrees below zero.
Reported. That's no less than 89.9 degrees Celsius, the coldest temperature ever officially recorded for a permanently inhabited settlement on the planet and the coldest in the northern hemisphere.
Where Is The Coldest Place On Earth?
According to Christopher Burt of Weather Underground, unofficial temperatures of as low as minus 108 degrees have been recorded in Oymyakon.
And the winter there is long and brutal, he said: There have been no records of temperatures above zero degrees Fahrenheit there since December. March 1st and 1st.
As for the world's coldest-ever temperature, it will almost certainly be in Antarctica, which was measured at 128.6 below zero in 1983 at the Vostok Research Station. In 1983, the Soviet Antarctic base at Vostok experienced the coldest temperatures ever recorded on Earth, according to the World Meteorological Organization. The Vostok station, which lies on about 3.7 kilometers of ice, is one of the most isolated research stations in the world.
It's hard to believe that this snow-covered desert experienced an extreme temperature drop of -89.2°C (-128.6°F), which is 30 degrees colder than the next lowest temperature ever recorded.

Located at the frigid North Pole of the Arctic Circle, Oymyakon is considered the coldest permanently inhabited place on earth. The lowest temperature ever recorded was -67.8 °C (-89.86 °F) in 1933. Schools in a settlement of 500 permanent residents are only likely to close when the temperature drops below -55°C (-67°F). This is usually the average minimum winter temperature, but only when the population is less than 500.
The Klinck Weather Station boasts of being the coldest place in the Arctic Circle. Located in central Greenland, the climate surpassed the Oymyakon record of December 1991 by about 2 degrees, reaching -69.6 °C (-93.28 °F). Despite these cold temperatures, the Greenland ice sheet is melting rapidly.
According to the world map, the ten countries with the lowest recorded temperatures are as follows.
Inadequate weather records from the past may explain why the past few decades have seen the highest and lowest temperatures on record in developing countries, particularly in Africa. Weather data from developing countries have only recently become available.

As in most places in the Northern Hemisphere, the months of January and February consistently produced the lowest temperatures on record in the history of weather model documentation. In the southern hemisphere, on the other hand, the lowest measured temperatures were recorded in June and July.
