The weather in Antarctica can be highly variable, and the weather conditions can often change dramatically in short periods of time. There are various classifications for describing weather conditions in Antarctica; restrictions given to workers during the different conditions vary by station and nation. [19] [20] [21]
Ice cap climate is the world's coldest climate, and includes the coldest places on Earth. With an average temperature of −55.2 °C (−67.4 °F), Vostok, Antarctica is the coldest place in the world, and has also recorded the lowest temperature, −89.2 °C (−128.6 °F). [3]
The station is at 750 m (2,460 ft) and the surrounding mountains at 1,100 m (3,600 ft), causing cold air to pool in the valley: recent studies show that winter temperatures in the area "increase" with elevation by as much as 10 °C (18 °F). [6] The average temperature in Oymyakon has risen about 2.7 degrees Celsius since preindustrial times.
During the Antarctic winter, the surface of central Antarctica becomes cooler than middle layers of the atmosphere; [26] this means greenhouse gases trap heat in the middle atmosphere, and reduce its flow toward the surface and toward space, rather than preventing the flow of heat from the lower atmosphere to the upper layers. This effect lasts ...
By 2009, researchers were able to combine historical weather-station data with satellite measurements to create consistent temperature records going back to 1957 that demonstrated warming of >0.05 °C/decade since 1957 across the continent, with cooling in East Antarctica offset by the average temperature increase of at least 0.176 ± 0.06 °C ...
Once the preserve of explorers and sea dogs, the Drake is today a daunting challenge for an ever-increasing number of travelers to Antarctica — and not just because it takes up to 48 hours to ...
Ahead of international climate talks, U.N. Secretary-General Antonio Guterres visited globally-important Antarctica, where ice that's been frozen for millions of years is melting due to human ...
Japanese stations in Antarctica Dome Fuji (ドームふじ Dōmu Fuji ), also called Dome F or Valkyrie Dome , is an Antarctic base located in the eastern part of Queen Maud Land . With an altitude of 3,810 metres (12,500 ft) above sea level, it is the second-highest summit or ice dome of the East Antarctic Ice Sheet and represents an ice divide .
