Abstract
Data associated with the manuscript, "Changing spatiotemporal patterns of seasonal to annual precipitation extremes in the U.S. Great Plains region", by Howlader et al.
Manuscript abstract: Precipitation extremes, such as droughts and floods, stress water management. Compound precipitation extremes include recurring extremes (consecutive wet or dry periods) and ‘weather whiplash’ events (transitions from anomalously wet to anomalously dry periods and vice versa) and are particularly stressful. We developed a percentile-based approach to quantify six typologies of extremes (isolated wet/dry, recurring wet/dry, dry-to-wet and wet-to-dry whiplash) in a consistent manner across time and space and investigated historical spatiotemporal dynamics in seasonal and annual precipitation extremes across the U.S. Great Plains (USGP), which spans 2.1 million km² in parts of 14 states. We identified each extreme type at annual and seasonal timescales and 4 km spatial resolution from 1895 to 2023. Annual and seasonal precipitation is increasing across much of the northern and eastern USGP, particularly during the spring, which is accompanied by significantly more frequent isolated wet and recurring wet extremes. In particular, recurring wet conditions have accelerated dramatically since the 1980s, both annually and in all seasons. In contrast, no annual or seasonal extreme type was decreasing in occurrence at the significance threshold used. Extremes are associated with El Niño–Southern Oscillation (ENSO) dynamics, with extreme wet conditions occurring more frequently during El Niño phases across the central and southern USGP and extreme dry conditions occurring more frequently during La Niña phases. Understanding historical changes offers insight into present and future conditions, and our findings underscore the need for water management strategies resilient to more common wet and recurring wet extremes.
