Atmospheric wave theory falls short in explaining rising extreme weather, study suggests

Across much of the northern hemisphere, extreme weather events like heat waves and heavy precipitation have increased in frequency and severity over the last several decades. A new study from the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) shows that one proposed partial explanation, so-called "quasiresonant amplification of quasistationary Rossby waves," may not be capable of explaining any of this increase in severe weather events.
