Core Viewpoint - The Shandong Meteorological Bureau has issued a yellow high-temperature warning, predicting temperatures above 35°C in inland areas from August 19 to 23 due to the influence of the subtropical high-pressure system [1]. Summary by Relevant Sections High-Temperature Forecast - From August 19 to 23, inland areas of Shandong are expected to experience high temperatures ranging from 35°C to 39°C, with some areas potentially reaching 40°C. Coastal regions will see temperatures between 30°C and 34°C [1]. Daily Weather Conditions - On August 19, cities such as Liaocheng, Dezhou (eastern), Binzhou (southern), Dongying (southern), Jinan, Zibo, Weifang, Tai'an, Heze, Jining, Zaozhuang, Linyi, Rizhao, and northern Qingdao will have temperatures between 35°C and 37°C, while other areas will range from 30°C to 34°C. The forecast for August 20 to 22 indicates similar high temperatures in inland areas [4][6][9]. Weather Patterns and Influences - The formation of high temperatures is attributed to specific weather systems, particularly the subtropical high-pressure system, which is known as a "messenger of high temperatures." Urban heat island effects and global warming are also contributing factors to the increasing frequency of extreme heat events [11].
