Abstract

The summer of 2010 was exceptionally warm in eastern Europe and large parts of Russia. We provide evidence that the anomalous 2010 warmth that caused adverse impacts exceeded the amplitude and spatial extent of the previous hottest summer of 2003. “Mega-heatwaves” such as the 2003 and 2010 events likely broke the 500-year-long seasonal temperature records over approximately 50% of Europe. According to regional multi-model experiments, the probability of a summer experiencing mega-heatwaves will increase by a factor of 5 to 10 within the next 40 years. However, the magnitude of the 2010 event was so extreme that despite this increase, the likelihood of an analog over the same region remains fairly low until the second half of the 21st century.

Figure 3 and the accompanying text are based on best-guess temperature reconstructions with relatively large uncertainties at regional and gridpoint scales and should therefore be interpreted with caution and not be overemphasized.
25
The concept of mega-heatwave is herein used to refer to regional mean temperature anomalies (over ~1 million km2) of extraordinary amplitude (approximately ≥3 SDs relative to the 1970–1999 period) at subseasonal scales (of at least 7 days), thus differing from the classic local heatwave definition.

Summer temperature variability is higher in EE, and hence, a given value in SDs actually implies larger anomalies in EE than in WE.
