VARIATION OF EURASIAN SNOW COVER EXTENT AND NORTHERN HEMISPHERE SURFACE AIR TEMPERATURE
Correlations between the snow cover extent and northern hemisphere mean surface air temperature (P. D. JONES et al. : J. Appl. Meteorol., 25,161,1986) were analyzed for 1967-1987. Snow cover extent in Central Asia (35-65°E, 25-70°N), which correlates better with the interannual variation of snow cov...

Correlations between the snow cover extent and northern hemisphere mean surface air temperature (P. D. JONES et al. : J. Appl. Meteorol., 25,161,1986) were analyzed for 1967-1987. Snow cover extent in Central Asia (35-65°E, 25-70°N), which correlates better with the interannual variation of snow cover extent over the whole continent than that in other regions, was chosen to represent the Eurasian snow cover (October, December, February and April). For snow cover extent data, the NOAA/NESDIS Northern Hemisphere Snow and Ice Chart was used. Negative correlations were found between the NHT in late summer to autumn (r=-0.67 for September) and the October snow cover extent. The so-called Eurasian Pattern (J. M. WALLACE and D. S.
