The Lancang–Mekong Region encompasses six countries, covering an area exceeding five million square kilometers and containing a population of more than 400 million. Floods in this region may cause extremely serious losses lives property. However, due to the severe shortage flood disaster data, loss data meteorological monitoring assessment risks remains highly formidable.

The study of impacts on and risks to citizens generated by climatic or environmental phenomena in urban settlements is made complex the coexistence events that can affect risk assessment. In this work, a model for assessment population heatwaves presence pandemic periods proposed. epidemics treated as stressor contributes altering exposure. To assess prevalence stressor, fuzzy-based emotion detection method utilized, which uses FREDoC framework categorize subzones comprise area according relevance pleasant unpleasant emotions citizens, identified based examination posts have been published social networks. proposed was tested city Naples Italy, taking into consideration heatwave scenario occurred summer 2021 during COVID-19 analyzing variation exposure thirty districts partitioned. findings demonstrate accurately represent range hazards associated with brought pandemic.

Against the backdrop of global warming, heatwaves in China have become more frequent, posing serious risks to public health and socio-economic stability. However, existing identification methods lack precision, driving mechanisms remain unclear. This study applies Excess Heat Factor (EHF) characterize across from 2013 2023, analyzing their spatiotemporal patterns exploring key drivers such as atmospheric circulation soil moisture. Key findings reveal significant regional differences: (1) Frequency Duration—The southeastern coastal regions (e.g., Yangtze River Delta) experience higher annual heatwave frequencies (1.75–3.5 events) but shorter durations (6.5–8.5 days). In contrast, arid northwest has both frequent (1.5–3.5 events per year) prolonged (8.5–14.5 days) heatwaves, while Tibetan Plateau sees weaker events. (2) Driving Factors—Heatwaves Delta are primarily driven by an intensified subtropical high, leading subsidence clear-sky conditions. Fujian, anomalous low-level winds enhance heat accumulation, areas show strong moisture–temperature coupling, where drier soils intensify warming. Conversely, moisture a influence on Plateau, suggesting dominant control. It is important note that EHF index used this does not directly account for humidity, which may limit its applicability humid regions. Additionally, ERA5 ERA5-Land reanalysis data were systematically validated against ground observations, introducing potential uncertainties.
