Impact of atmospheric circulation variability on U.S. Midwest moisture sources

Carr, T., & Ummenhofer, C. C. (2024). Impact of atmospheric circulation variability on U.S. Midwest moisture sources. Journal of Climate, 37, 59-75. https://doi.org/10.1175/JCLI-D-23-0178.1 Estimates of future changes in precipitation over land are poorly constrained owing to uncertainty about changes in atmospheric circulation and specific humidity over land. Recent work suggests one way to better-constrain these land precipitation…
