The impacts of flash droughts on crop yields differ from traditional slow-onset droughts and the underlying mechanisms remain inadequately quantified. Most process-based crop models have been developed for slow-onset droughts and may not accurately capture the effects of flash droughts.

The study's findings are limited to the United States and may not be generalizable to other regions. The study relies on observational data and may not capture the full range of variability in maize yield responses to flash droughts. Most process-based crop models systematically underestimate yield sensitivity to flash droughts, highlighting the need for improved model development.
