Identification and Analysis of Heatwave Events Considering Temporal Continuity and Spatial Dynamics

In the context of global warming, general increase in temperature has led to an heatwave events, as well a dramatic intensification economic losses and social risks. This study employs latest intensity–area–duration (IAD) framework that takes into account temporal continuity spatial dynamics extreme events identify regional extracts key parameters associated changes frequency, intensity, influence area, duration seven geographic subregions China 1979–2018 period. Heatwaves all durations increased frequency intensity during research period, with shorter heatwaves increasing at faster rate than longer heatwaves. Among subregions, Xinjiang (XJ) Southern (SC) are regions most frequent occurrence, while Southwest (SW) SC have highest frequency. terms distributions, XJ strongest event largest affected longest duration. However, trends, SC, XJ, SW rates growth, duration, respectively. addition, extended vast areas more likely occur their is on rise. During length occurrences exhibited upward tendency, it was shown greater broader area. evolutionary characteristics indicate certain consistency influence. These findings can contribute development strategies prepare for mitigate adverse effects occurrences.
