Compound hot-dry-windy events (HDW) significantly increased in the U.S. Great Plains from 1982 to 2020, causing a 4% winter wheat yield reduction per 10 h of HDW during heading to maturity. These events, overlooked in traditional risk assessments, are associated with yield reduction rates up to 0.09 t ha⁻¹ per decade and are atmospherically linked to the Pacific Decadal Oscillation. Losses were concentrated in areas historically affected by the Dust Bowl.
