Evaluation of the applicability of multiple drought indices in the core zone of 'westerlies-dominated climatic regime'

With the intensification of global warming, different regions are facing constantly changing hydroclimatic conditions, which brings significant uncertainties to the assessment of dry-wet under the backdrop of global warming and the study of drought events. The core zone of "westerlies-dominated climatic regime" primarily includes the five Central Asian countries and China's Xinjiang, located in the heartland of the Eurasian continent and dominated by westerly circulation.
