Drivers behind the summer 2010 wave train leading to Russian heatwave and Pakistan flooding

G. D. Capua, S. Sparrow, et al.

In the summer of 2010, a staggering heatwave in Russia and devastating floods in Pakistan occurred simultaneously, tied together by an atmospheric wave train. This research reveals how unusual sea surface temperatures, soil moisture deficits, and land warming fueled these extreme events, conducted by authors from renowned institutions.

Abstract
Summer 2010 witnessed simultaneous extreme weather events: a record-breaking heatwave in Russia and severe floods in Pakistan, linked by an atmospheric wave train. Using a large ensemble climate model, the study reveals that the wave train's occurrence was influenced by three key drivers: 2010 sea surface temperature anomalies, early-summer soil moisture deficit in Russia, and high-latitude land warming. These factors interacted synergistically, increasing the probability of the joint events.
