Special Issue Information

Dear Colleagues,

Increasing surface temperatures associated with global climate change are projected to cause heatwaves and droughts to become more frequent and extreme in many parts of the world. Moreover, there exists a potential interplay between drought and heatwave events, which means that drought can exacerbate the severity of heatwave events, and vice versa. These extreme events have had a significant impact on the environmental ecosystem and socioeconomic activities, which is expected to worsen in the future, especially with the compounded effects of drought and heatwave (CDHW) episodes. Although some effort has been made to investigate the temporal and spatial variations of drought and heatwaves, the knowledge regarding their interplay and associated mechanisms is still limited. Therefore, this Special Issue focuses on exploring the variations and interplay of drought and heatwaves and uncovering the associated mechanisms and impacts. The previous volume of Exploring the Variations and Interplay of Drought and Heatwaves: Uncovering the Associated Mechanisms and Impacts was a great success.

This new Special Issue aims to continue collecting high quality contribution may focus on, but are not limited to:

  • Identification and variation analysis of regional drought and heatwave events;
  • The interplay between climate variability and drought and heatwaves;
  • Exploring the implication or impacts of drought and heatwaves;
  • Projecting the variations of drought and heatwaves in different climate scenarios;
  • Compound drought and heatwave (CDHW) events;
  • Uncovering the interactions between drought and heatwaves at different scales;
  • Remote sensing and early warning systems for drought and heatwaves;
  • Clarifying the mechanisms behind drought and heatwaves;
  • Adaptation strategies for drought and heatwaves.

Arid and semi-arid regions are highly sensitive and vulnerable to climate change and human activities. Clarifying their spatial distribution is of great significance for understanding regional drought dynamics. This research examines the Shendong mining region, employing time series data of vegetation growth anomalies derived from total primary productivity data to delineate ecological drought. The SPI dataset, representing meteorological drought, is utilized to identify drought frequency, duration, and intensity for both types of droughts based on the run theory. The drought characteristics of different land use patterns are analyzed, and the center of gravity of meteorological and ecological droughts in the study area are calculated. The results show the following: (1) The frequency, duration, and intensity of meteorological drought in the Shendong mining area are 0.74 times per year, 9.2 months, and 0.91, respectively. The frequency, duration, and intensity of ecological drought are 0.33 times per year, 18.2 months, and 0.09, respectively. (2) The intensity of meteorological and ecological droughts is generally consistent across different land use types. The frequency of meteorological drought is minimal for croplands and high-coverage grasslands. The duration of meteorological drought is shortest for high-coverage grasslands. High- and medium-to-high-coverage grasslands and cultivated lands have lower ecological drought frequencies. Low- and medium-to-low-coverage grasslands have relatively shorter ecological drought durations. (3) In regions where land use alterations are evident, the frequency and duration of meteorological drought in areas where cropland has been converted to grassland are relatively low. The frequency, duration, and intensity of ecological drought for croplands converted to grasslands and grasslands converted to croplands are similar. (4) The average incidence of meteorological drought transitioning into ecological drought in the study area is roughly 55%, with areas of stable land use demonstrating a more robust correlation between meteorological and ecological drought in croplands. In the converted areas, the correlation between meteorological drought and ecological drought is higher for croplands converted to grasslands. (5) The transition frequency from meteorological drought to ecological drought exceeds 60% in mining areas. Compared to other mining areas, the meteorological drought intensity near Jitu well and Daliuta well is notably higher. The research findings reveal the spatial distribution attributes and transition dynamics of meteorological and ecological droughts in the Shendong coal mining region, providing reference for the implementation of ecological restoration projects and protection measures in the area.
