The temperature record was discovered nearly 30 years later by the climate detective of WMO’s weather and climate extremes archive. This temperature is lower than – 67.8 ° C recorded at verkhoyanksk station (February 1892) and oimekon station (January 1933) in Russia. The world minimum temperature record was – 89.2 ° C (- 128.6 ° f) on July 21, 1983, which was maintained by the high altitude Vostok weather station in Antarctica. WMO weather and climate extremes archive contains records of the world’s highest and lowest temperature, rainfall, heaviest hail, longest drought period, Maximum gust, longest lightning and weather related deaths. < p > < p > the weather station verkhoyanksk, which previously kept a record of low temperatures in the northern hemisphere, recorded a temperature of 38 ° C in a Siberian heat wave on June 20, making headlines. At present, WMO is verifying whether this is a new record of high temperatures north of the Arctic Circle (a new category in the archive). Guided by the assessment, the ongoing survey will also examine possible past high temperatures north of the Arctic circle. < / P > < p > “in the era of climate change, people’s attention is mostly focused on the new record of high temperature. This newly confirmed record of low temperature is an important reminder of the sharp contrast on the planet Professor Petrie Talas, WMO secretary general, said. “It is this testimony to the dedication of climatologists and meteorologists that now enables us to investigate many older records and strive for a more comprehensive understanding not only of current climate extremes, but also of historical climatic extremes,” Professor Talas said. Most of the extreme climate observations assessed by WMO “weather and climate extremes archive” have been carried out in recent years. However, climate historians occasionally find some meteorological data that have been ignored for a long time but contain important climate information and need to be analyzed and verified. This is the case with the just completed assessment of the weather records of a remote automatic weather station in Greenland called Klinck nearly 30 years ago, at an altitude of 3105 meters, close to the top of the Greenland ice sheet. < / P > < p > the automatic weather station, part of the University of Wisconsin Madison network, operated for two years in the early 1990s to record weather conditions around the Greenland peak during its Greenland ice sheet project. In 1994, it was sent back to the laboratory for testing and then sent to the south pole for use. < / P > < p > this occurred before WMO began to assess global extremes, as the world weather and climate extremes archive was established only in 2007. The record came to light only after the WMO International Polar scientists senior expert group tracked down the original scientists involved. The Committee praised the scientists of the station’s original project for their careful calibration and metadata maintenance of an observation so long ago. This diligence demonstrates a high degree of attention to detail and the high quality of observation. After extensive analysis of equipment, observation methods and weather conditions in December 1991, the expert group unanimously recommended that the observation be accepted as an effective observation. < / P > < p > “this survey highlights the ability of today’s climatologists not only to identify modern climate records, but also to act as’ climate detectives’ to discover important past climate records – thus creating high-quality long-term climate records for climate sensitive regions of the world,” said Professor Randall cerveny, WMO’s climate and weather extreme report. < / P > < p > according to George Weidner, who helped design the automatic weather station, all components of the station must be selected to work in extremely cold conditions. “In Greenland, all sites are installed by snowmobiles. So the automatic weather station must be well packed, so that it can be intact after crossing the rough snow surface. Our years of packing experience in Antarctica has helped make automatic weather stations safe and secure on snowmobiles He said. < / P > < p > Manola brunet [Center for climate change (C3), Department of geography, University of ravela welgili, taragonaro, Spain, and Institute of climate research, School of Environmental Sciences, University of East Anglia, UK; chairman of WMO CCL] < / P > < p > Matthew Lazzara [Madison District Institute of technology and University of Wisconsin Madison, Madison, Wisconsin, USA] < p > < p > George Weidner [Department of atmospheric and Marine Sciences, University of Wisconsin Madison, Madison, USA] < A= https://ibmwl.com/category/global-tech/ target=_ blank>Global Tech
