Taking on this challenge, Dr. WANG Lin from the Institute of Atmospheric Physics at the Chinese Academy of Sciences introduces the concept of "super drought." This theoretical framework, published in Bulletin of the American Meteorological Society, highlights the simultaneous occurrence of extreme droughts at multiple time scales, shedding light on the compound dry extremes that impact water resources and result in significant water storage loss. It acts as a vital differentiator, separating high-impact droughts from those with milder consequences.

 

"To provide a quantitative representation of this concept, we have developed the Comprehensive Multiscalar Index (CMI) using the innovative vine copula framework," explains Dr. WANG. The CMI offers a pioneering approach to monitor super droughts, representing a significant advancement in our understanding of extreme events within the context of drought. Its potential applications are wide-ranging and hold great promise.

 

Recognizing the importance of international collaboration, Dr. WANG is committed to enhancing China's influence in the field of drought index and monitoring. In pursuit of global accessibility, he has launched the web service, superdrought.com. This platform provides near-real-time monitoring of global super drought events, enabling users to stay informed about the latest developments. Additionally, the website serves as a comprehensive historical data repository, offering invaluable insights to researchers, policymakers, and interested individuals.

 

"At superdrought.com, our utmost priorities are transparency and accessibility," Dr. WANG emphasizes. Through this public website, end users and decision-makers can effortlessly access both near-real-time monitoring data and an extensive historical data archive.

"Our goal is to empower individuals and organizations with the necessary tools to navigate the challenges posed by super droughts." Dr. WANG hopes."Together, we can work towards improved anticipation and mitigation strategies, safeguarding our water resources and communities."
