Abstract
Decadal trends have been noted in the leading mode of boreal winter variability. Given that this mode is thought to be an
internal mode of the atmosphere it remains unclear as to what is responsible for interannual to interdecadal oscillations
of this mode. We demonstrate that continental-scale snow cover varies at the same multi-year time periods as the atmosphere
but leads the atmosphere by several months through their mutual oscillations. Therefore we propose snow cover as a potential
contributor to the interannual variability of the leading boreal winter mode of the atmosphere.
