Abstract EN
During the summer of 2010, an unusually persistent blocking episode resulted in anomalously warm dry weather over the European part of Russia.
The excessive heat resulted in forest and peat fires, impacted terrestrial ecosystems, greatly increased pollution in urban areas, and increased mortality rates in the region.
Using the National Centers for Atmospheric Research (NCAR), National Centers for Environmental Prediction (NCEP) reanalysis datasets, the climatological and dynamic character of blocking events for summer 2010 and a precursor May blocking event were examined.
We found that these events were stronger and longer lived than typical warm season events.
Using dynamic methods, we demonstrate that the July 2010 event was a synoptic-scale dominant blocking event; unusual in the summer season.
An analysis of phase diagrams demonstrated that the planetary-scale did not become stable until almost one week after block onset.
For all other blocking events studied here and previously, the planetary-scale became stable around onset.
Analysis using area integrated regional enstrophy (IRE) demonstrated that for the July 2010 event, synoptic-scale IRE increased at block onset.
This was similar for the May 2010 event, but different from case studies examined previously that demonstrated the planetary-scale IRE was prominent at block onset.
