Core Viewpoint - The article discusses the discrepancies between forecasted temperatures and perceived temperatures during high heat events, emphasizing the role of humidity and individual factors in shaping personal comfort levels [1][2]. Group 1: Weather Forecasting - The China Meteorological Administration (CMA) predicts sustained high temperatures in various regions, including southern Hebei, Huanghuai, Jianghan, Jianghuai, northern Jiangnan, Guanzhong in Shaanxi, and the Sichuan Basin [1]. - Meteorologists are held accountable for their forecasts, as inaccurate predictions can affect their scoring, motivating them to improve accuracy [1]. - The temperature reported by meteorological departments is measured using standardized equipment, which may not reflect the higher temperatures experienced on surfaces like concrete or asphalt [1]. Group 2: Perceived Temperature - The difference between forecasted temperatures and personal comfort is attributed to various environmental factors, including humidity, air pressure, and wind [2]. - High humidity can significantly affect perceived temperature, with discomfort felt at around 33°C and 80% humidity [2]. - Individual differences, such as body type, clothing, activity level, and even mood, can influence how temperature is perceived [2]. Group 3: Health Risks and Warnings - The CMA and the National Health Commission have issued a national-level heat health risk warning system, categorizing risks into five levels based on health impacts related to high temperatures [2]. - Public recommendations include maintaining cool indoor environments, avoiding outdoor activities during peak heat, and ensuring adequate hydration to mitigate health risks associated with high temperatures [2].
