To investigate the three-dimensional spatiotemporal propagation characteristics of meteorological drought, based on the CN05.1 gridded data and standardized precipitation index (SPI) during the period 1961-2021 in China, a spatiotemporally continuous event identification method and hierarchical clustering algorithms were applied to classify different propagation patterns of spatiotemporally continuous meteorological droughts and analyze their characteristics. The changing characteristics of events in future climate scenarios were discussed. The results indicate that the spatiotemporal continuous meteorological drought events distribute widely with significant variations in their movement distances, ranging from localized areas to nearly half of China. Three propagation patterns are identified based on movement distance and direction. The Type 1 and Type 2 events are characterized by long duration and large affected areas but occurring less frequently. The Type 3 events occur more frequently, have shorter durations, and affect smaller areas. Under future scenarios, the total number of spatiotemporally continuous drought events is projected to increase, while their duration and intensity are expected to decrease. Both the maximum and total affected areas are likely to expand.

为揭示气象干旱的三维时空传播特征,基于中国区域1961~2021年的CN05.1格点数据集和标准化降水指数,采用时空连续性事件识别方法和层次聚类算法,识别时空连续性气象干旱事件并划分不同传播模式,分析了各模式的特征,并探讨了未来气候情景下事件的变化特征。结果表明,时空连续性气象干旱事件分布较广,移动距离差异显著,覆盖范围从局部地区延伸至近半个国土面积;基于移动距离和移动方向可划分为三类传播模式,类型1和类型2事件呈现持续时间长、空间范围广特征,但发生频率较低;类型3事件则以高频次、短持续时间和局部影响为主要特点;未来情景下,时空连续性气象干旱事件的总频次增加,但其平均持续时间和强度趋于减弱,最大影响面积与累计影响范围则均呈扩张特征。

为揭示气象干旱的三维时空传播特征,基于中国区域1961~2021年的CN05.1格点数据集和标准化降水指数,采用时空连续性事件识别方法和层次聚类算法,识别时空连续性气象干旱事件并划分不同传播模式,分析了各模式的特征,并探讨了未来气候情景下事件的变化特征。结果表明,时空连续性气象干旱事件分布较广,移动距离差异显著,覆盖范围从局部地区延伸至近半个国土面积;基于移动距离和移动方向可划分为三类传播模式,类型1和类型2事件呈现持续时间长、空间范围广特征,但发生频率较低;类型3事件则以高频次、短持续时间和局部影响为主要特点;未来情景下,时空连续性气象干旱事件的总频次增加,但其平均持续时间和强度趋于减弱,最大影响面积与累计影响范围则均呈扩张特征。

To investigate the three-dimensional spatiotemporal propagation characteristics of meteorological drought, based on the CN05.1 gridded data and standardized precipitation index (SPI) during the period 1961-2021 in China, a spatiotemporally continuous event identification method and hierarchical clustering algorithms were applied to classify different propagation patterns of spatiotemporally continuous meteorological droughts and analyze their characteristics. The changing characteristics of events in future climate scenarios were discussed. The results indicate that the spatiotemporal continuous meteorological drought events distribute widely with significant variations in their movement distances, ranging from localized areas to nearly half of China. Three propagation patterns are identified based on movement distance and direction. The Type 1 and Type 2 events are characterized by long duration and large affected areas but occurring less frequently. The Type 3 events occur more frequently, have shorter durations, and affect smaller areas. Under future scenarios, the total number of spatiotemporally continuous drought events is projected to increase, while their duration and intensity are expected to decrease. Both the maximum and total affected areas are likely to expand.
