Northern hemisphere winter storm tracks of the Eemian interglacial and the last glacial inception
International audience Climate simulations of the Eemian interglacial and the last glacial inception have been performed by forcing a coupled ocean-atmosphere general circulation model with insolation patterns of these periods. The parameters of the Earth's orbit have been set to conditions of...

International audience Climate simulations of the Eemian interglacial and the last glacial inception have been performed by forcing a coupled ocean-atmosphere general circulation model with insolation patterns of these periods.

Compared to today, these dates represent periods with enhanced and weakened seasonality of insolation in the northern hemisphere.

The change in the orbital configuration has a strong impact on the meridional temperature gradients and therefore on strength and location of the storm tracks.
