"Internal atmosphere-land interactions in Eurasia are believed to be an important factor in triggering abnormal summer temperatures. However, the exact reasons for such interactions causing heat waves remain largely unclear," says Associate Professor Tomonori Sato of the research team.
In the present study published in Scientific Reports, Tomonori Sato and Tetsu Nakamura of Hokkaido University examined a large dataset derived from the "database for Policy Decision making for Future climate change" (d4PDF). The database comprises data spanning over a 60-year period (1951-2010) which incorporates observed sea surface temperature, sea ice, and natural and anthropogenic forcing.

The researchers analyzed 6,000 patterns in the spatial distribution of summer temperatures in Eurasia, and succeeded in dividing past summer temperature variations into two groups -- one attributable to global warming and the other...
