In response to the increasing frequency and intensity of multivariate compound events under global warming, along with their growing cascading disaster effects and complex nonlinear impacts, this study employed Vine Copula functions to assess the risk of trivariate compound events, involving meteorological drought, high temperature, and agricultural drought in summer of the Yellow River Basin. It further quantified the risk of agricultural drought at mild level or above under the conditions of specific severities of meteorological drought and/or high temperature. Results show that high-risk hotspots of the concurrent meteorological drought, high temperature, and agricultural drought(i.e., trivariate “AND events”) are primarily located in the middle and lower reaches of the basin. Compared to the northwestern regions, the eastern areas face higher risks of the “AND events” and the cooccurence of meteorological drought/high temperature and agricultural drought (i.e., trivariate “OR events”). Under conditions where meteorological drought and high temperature of different severities occur simultaneously, or at least one of them occurs, the risk of agricultural drought at mild level or above in the eastern parts of the basin is significantly higher than that in the western regions.
