The United Nations’ World Meteorological Organization acknowledged a brand new document excessive temperature for Antarctica on July 1. On February 6, 2020, Esperanza Station (Argentine Research Center in Trinity Peninsula) skilled 18.3 °C.
“Verification of this most temperature document is necessary as a result of it helps us construct an image of climate and local weather in one among Earth’s remaining frontiers. Even extra so than the Arctic, the Antarctic is by way of steady and steady climate and local weather observations and forecasts. is poorly lined, regardless that each local weather and sea patterns play a big position in driving and sea degree rise,” stated WMO Secretary- General Prof. Petri Talas stated in an announcement.
“The Antarctic Peninsula is one of the fastest warming regions of the planet, about 3 °C over the past 50 years. So this new temperature record is consistent with the climate change we are seeing.” The earlier document excessive temperature was 17.5 °C, recorded on 24 March 2015 on the identical station.
A WMO committee performed in depth research to know the climate situations in the course of the time of the reported document and famous that a big excessive strain system within the space precipitated the Föhn situations.
“Föhn or Foehn winds are normally categorised by the motion of sizzling dry air that descends or descends down a mountain. When the wind hits the mountain in its path, it rises up and over the mountain. causes precipitation on the facet of the mountain, whereas the decrease facet of the mountain turns into dry and sizzling. These winds can heat the air floor temperature downstream by a number of levels over a protracted time period,” stated Goa’s National Center for Polar and Ocean Research, Atmosphere-Ocean Interaction Studies Division Sourav Chatterjee defined.
“Although ice melting occurs mostly in the presence of sunlight in the summer, these Fohn winds can also cause significant melting during the dark polar winters,” he stated.
“Rising global air and ocean temperatures are threatening ice sheets and glaciers in the polar regions. Warmer temperatures and the increasing strength of westerly winds may increase the melting of the Antarctic ice sheet due to the influence of the Fohen wind even in winter,” he stated.
