近期多地遭受热浪“烤”验，专家表示——副热带高压“惹的祸”，公众须防护

Core Viewpoint - The recent extreme heat wave in China is attributed to the stable maintenance of the subtropical high pressure and continental high pressure, leading to significant warming effects across various regions [1][2]. Group 1: Causes of the Heat Wave - The extreme heat in northern regions is primarily caused by continental high pressure and the formation of subtropical high pressure [2]. - The subtropical high pressure has moved northward rapidly this year, affecting areas like Henan, which typically would not experience such conditions until later in the summer [2]. Group 2: Temperature Records - As of July 13, 150 national meteorological observation stations recorded daily maximum temperatures that broke local historical records for July [1]. - In key high-temperature areas such as eastern Shandong and northern Jiangsu, 15 stations set new historical high-temperature records since their establishment [1]. Group 3: Future Temperature Predictions - Over the next 10 days, regions including central and southern North China, Huanghuai, Jianghan, and Guanzhong in Shaanxi are expected to experience sustained high temperatures, with daily maximums exceeding 35°C for 4 to 7 days [3]. - The peak of this heat wave is anticipated on July 15-16, with some areas reaching maximum temperatures of 39°C to 42°C [3]. Group 4: Public Advisory - Due to the significant temperature differences between northern and southern regions, the public is advised to take protective measures against the heat, especially vulnerable groups such as the elderly, children, and those with pre-existing health conditions [3].
