UN company confirms document warmth of 18.3 levels Celsius in Antarctica

The United Nations’ World Meteorological Organization, on July 1, recognised a brand new document excessive temperature for Antarctica. On February 6, 2020, the Esperanza station (the Argentine analysis station in Trinity Peninsula) skilled 18.3 levels Celsius.
“Verification of this maximum temperature record is important because it helps us to build up a picture of the weather and climate in one of Earth’s final frontiers. Even more so than the Arctic, the Antarctic is poorly covered in terms of continuous and sustained weather and climate observations and forecasts, even though both play an important role in driving climate and ocean patterns and in sea-level rise,” mentioned WMO Secretary-General Prof. Petteri Taalas in an announcement.
“The Antarctic Peninsula is among the fastest-warming regions of the planet, almost 3°C over the last 50 years. This new temperature record is therefore consistent with the climate change we are observing.” The earlier document for prime temperature was 17.5 levels Celsius, recorded on March 24, 2015, on the similar station.
A WMO committee carried out in depth research to grasp the climate state of affairs throughout the time of the reported information and famous that a big high-pressure system over the world has created Föhn circumstances.
“Föhn or Foehn winds are generally categorised by warm dry air motion descending in the lee or downwind side of a mountain. When the wind hits the mountain in its way, it rises above and causes precipitation in the upwind side of the mountain, while the downwind side of the mountain becomes dry and warm. These winds can warm the surface air temperature in the downwind side by several degrees for a prolonged time,” defined Sourav Chatterjee from the Atmosphere-Ocean Interaction Studies Division, National Centre for Polar and Ocean Research, Goa.
“Although the melting of ice mostly happens in summer in the presence of sunlight, these Foehn winds can cause significant melting during even dark polar winters,” he mentioned.
“Rising global air and ocean temperature are posing a threat to ice sheets and glaciers in the polar regions. The warming temperature and increasing strength of westerly winds can enhance the Antarctic ice sheet melting even in winter due to the Foehn wind effect,” he added.
