Surface temperature of Antarctica in winter and summer from the European Centre for Medium-Range Weather Forecasts. The climate of Antarctica is the coldest on Earth.The continent is also extremely dry (it is a desert [1]), averaging 166 mm (6.5 in) of precipitation per year.
The highest temperature ever recorded at McMurdo was 10.8 °C on December 21, 1987. There is enough snowmelt in summer that a few species of moss and lichen can grow. The average yearly temperature is freezing, but it can get as high as 8°C (46°F) in the austral summer and as low as -50°C (-58°F) in the austral winter.
The warmest recorded temperature at Vostok is −14.0 °C (6.8 °F), which occurred on 5 January 1974. [26] The coldest month was August 1987 with a mean temperature of −75.4 °C (−103.7 °F) and the warmest month was December 1989 with a mean temperature of −28 °C (−18 °F). [25]
The maximum recorded at Concordia on 17 March was -16.9 °C Pending the final data, in Vostok the value of -20.3 °C set the new monthly record but also exceeds the maximum of February (-22.2 °C ...
Casado said data from dozens of ice cores collected throughout the ice sheet has allowed him to reconstruct temperature patterns in Antarctica dating back 800,000 years.
Antarctica has the lowest naturally occurring temperature ever recorded: −89.2 °C (−128.6 °F) at Vostok Station in 1983. [4] It is also extremely dry (technically a desert , or so called polar desert ), averaging 166 millimetres (6.5 in) of precipitation per year, as weather fronts rarely penetrate far into the continent.
The latest data shows high temperatures in portions of East Antarctica – where the most abnormal conditions are ongoing – that are typically between minus 58 and minus 76 degrees Fahrenheit ...
Due to the partial melting of snow in summer due to above freezing daytime temperatures, animals as well as limited plant life (moss, lichens, and worts) are able to thrive during the warmer months of December, January, and February. Mean monthly temperatures range from −15.1 °C (4.8 °F) in June to −1.7 °C (28.9 °F) in December. [18]
