Deadly April rainfall in US South and Midwest was intensified by climate change, scientists say

Climate change made recent flooding in Midwest, South more intense, report finds

Analysis from World Weather Attribution, a climate science group, found that human-caused global warming made the record-breaking downpours in early April about 9% heavier.

Influence of Anthropogenic Climate Change on Planetary Wave Resonance and Extreme Weather Events

Persistent episodes of extreme weather in the Northern Hemisphere summer have been shown to be associated with the presence of high-amplitude quasi-stationary atmospheric Rossby waves within a particular wavelength range (zonal wavenumber 6–8). The underlying mechanistic relationship involves the phenomenon of quasi-resonant amplification (QRA) of synoptic-scale waves with that wavenumber range becoming trapped within an effective mid-latitude a…

Deadly April rainfall in US South and Midwest was intensified by climate change, scientists say

Human-caused climate change intensified deadly rainfall in Kentucky, Tennessee, Arkansas and other states in early April and made it more likely to occur.

Climate change made April flooding worse, study says

The historic rain and flooding in parts of Arkansas, Kentucky and other states caused by intense April thunderstorms was likelier and also more intense because of climate change.
