Core Viewpoint - The recent high-temperature weather in China, with some regions exceeding 40°C, is expected to have significant impacts on social and economic activities, particularly during the critical "three summers" agricultural period [1][2]. Group 1: Affected Regions and Duration - The high-temperature center from June 1 to 7 was primarily located in Xinjiang Turpan and Huanghuai, with Turpan reaching a maximum temperature of 46.8°C [2][4]. - High temperatures were reported in provinces such as Henan, Hebei, Tianjin, Beijing, Shandong, Xinjiang, Shanxi, and Hubei, with Henan experiencing temperatures above 37°C for most of the week [2][4]. - The high-temperature weather in Xinjiang is expected to last until June 13, while Henan's high temperatures are predicted to continue, with a slight decrease on June 10 [2][3]. Group 2: Causes of High Temperatures - The occurrence of high temperatures is attributed to global warming and the influence of warm high-pressure systems, leading to dry and sunny weather conditions [4]. - Some weather stations, such as Linzhou in Henan, recorded historical temperature extremes, indicating that while the current heat is unusual, it is not unprecedented for this time of year [4]. Group 3: Impacts on Society and Economy - The high temperatures are causing increased electricity demand due to higher usage of air conditioning and cooling systems, which poses risks to energy system stability [5]. - Health risks are heightened, with increased chances of heatstroke, prompting adjustments in outdoor work schedules and the opening of cooling centers [5][6]. - The high temperatures also raise fire risks in forests and grasslands, necessitating preventive measures [6]. Group 4: Agricultural Implications - The ongoing high temperatures are occurring during the "three summers" agricultural busy period, with over 65% of winter wheat harvested by June 8 [7]. - While the heat can accelerate the drying and harvesting of winter wheat, it poses risks to crops in critical growth stages, such as wheat in Xinjiang, potentially affecting yield [8]. - Soil moisture levels are declining, which could exacerbate drought conditions and impact summer planting, with recommendations for timely planting and protective measures for agricultural workers [8].
