Core Viewpoint - The article discusses the reasons why people feel hotter than the temperature reported by meteorological agencies, particularly during the ongoing high-temperature weather in China. It highlights the differences between measured temperatures and perceived temperatures due to various environmental factors. Group 1: Temperature Measurement and Perception - Meteorological temperature is measured in a standardized environment, specifically in a Stevenson screen located 1.5 meters above grass, which may not reflect ground-level temperatures in urban areas [3] - Urban surfaces like concrete and asphalt can be 4 to 5 degrees Celsius hotter than the temperature recorded in the Stevenson screen due to direct sunlight and heat absorption [3] - Perceived temperature, or "feels-like" temperature, is influenced by multiple factors including air pressure, wind, and humidity, making it subjective and variable among individuals [3] Group 2: Weather Patterns and Conditions - This year, the subtropical high pressure has moved northward earlier and has a larger influence, leading to significant moisture transport and higher humidity levels, resulting in a "sauna-like" environment in cities like Beijing [4] - The ongoing high-temperature weather is characterized by a long duration and wide impact, particularly in southern regions where humidity is notably high [5] Group 3: Public Health and Safety Recommendations - Experts advise the public to minimize outdoor activities during high temperatures and for those working outdoors to take necessary protective measures [5] - A national-level heat health risk warning system has been established, categorizing risks into five levels, allowing the public to take appropriate actions such as staying cool indoors and ensuring adequate hydration [5]
