Study: Probability of high temperatures reaching 40 degrees Celsius increases in some parts of Northern Europe Xinhua News Agency, Helsinki, November 3 (Reporters Joe Haochen and Shu Qian) A new study by the Finnish Meteorological Institute shows that due to the impact of global climate change, the probability of extreme high temperatures of 40 degrees Celsius in the three Nordic countries of Finland, Sweden and Norway has increased significantly, and now It increased to 1981 times. The Finnish Meteorological Institute recently published a bulletin saying that many places in Europe have experienced high temperatures over 40 degrees Celsius in recent years, but the three Nordic countries mentioned above have yet to experience such extreme high temperatures. The highest temperature recorded in the region is 38 degrees Celsius, measured in Sweden in 1933 and 1947. However, the risk of breaking this historical record is increasing. The study analyzed seasonal forecast data from the European Center for Medium-Range Weather Forecasts from 1981 to 2025. The study estimates that under current climate conditions, the probability of a temperature of 40 degrees Celsius or higher somewhere in the region is about 0.53%, about six times the probability of a temperature of 3 degrees Celsius existing in the existing region. per year is about 4%, which is equivalent to happening about once every 25 years. The researchers noted that although the probability of extreme high temperatures of 40 degrees Celsius is still relatively low, this does not mean that it is impossible to happen. The study also sheds light on possible causes of unusually high temperatures in northern Europe. Researchers believe that the combination of high pressure, extremely strong blocking and abnormally dry land could raise local temperatures to unprecedented levels. Blocking high pressure contributes to continued high temperature weather; While dry soil will reduce water evaporation, which can further increase the temperature. Researchers noted that many countries mainly formulate high-temperature response indices based on historical observational data, but extreme weather that has not appeared in history may now have the conditions to occur. Relying on historical experience can lead to an underestimation of extreme high temperature risks. There is a need for the Nordic countries to reassess high temperature risks and prepare for a response in advance. Relevant research articles were published in "Nature Cooperation Journal-Natural Disasters".
