  • Response for anomalous circulation in relation to snow coverage is derived by use of regression coefficients in dealing with the Eurasian snow cover time series and northern mid and upper tropospheric height data, Results show that not only does the regression response pattern represent the correlation between snow coverage and circulation change but reflects the amplitude strength in correlation cores as well, with a greater amplitude or the circulation response in the mid troposphere and remarkable equivalent barotropy in the mid to upper levels, and that the response of winter-summer circulations to winter snow cover displays noticeable stationary planetary-scale wavetrain, leading to NEUP and NPNA patterns in winter, slightly changed forms in spring months and LEU and EANA in summer time. Also, the study demonstrates that the response-produced wavetrain is marked by branch and propagates ener-gy in a wave-front manner with the energy trapped at subtropical latitudes.

Also, the study demonstrates that the response-produced wavetrain is marked by branch and propagates ener-gy in a wave-front manner with the energy trapped at subtropical latitudes.
