ABSTRACT The concurrent occurrences of drought and extreme heat events, such as heatwaves, present substantial threats to human health ecosystems. This study delves into a thorough examination the collective impacts events in Southeast Asia (SEA) over past 83 years (1941–2023). Two primary definitions guided investigation: Compound Drought Heatwave Events (CDHW) Hot Droughts (CHD). Wet‐Bulb Globe Temperature (WBGT) was employed define heatwaves hot while Standardised Precipitation Evapotranspiration Index (SPEI) used for definition. In addition, explored impact linear detrending on copula fitting, assessing its effects. findings consistently revealed strong positive correlation between CDHW. On other hand, CHD exhibited varied patterns across regions. Furthermore, highlighted that had lower sensitivity CDHW compared CHD. analysis uncovered significant regional disparities joint return period ranking compound stemming from diverse approaches. Particularly non‐continental SEA, notably some regions like Sumatra Island, noteworthy distinction emerged, indicating limited applicability scenarios with stringent concurrence events. These insights provide valuable assistance research community, aiding discernment distinctions heat‐event assessment.

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.
