Autumn Eurasian snow depth, autumn Arctic sea ice cover and East Asian winter monsoon
ABSTRACT We present observational evidence and model simulation demonstrating a significant change in the early 1990s in the relationships of the autumn Eurasian snow depth ( AESD ) and the autumn Arctic sea ice cover ( ASIC ) with the East Asian winter monsoon ( EAWM ). A weakening of the AESD–EAWM...
