Under climate change scenarios, it is quite certain that high latitude regions will experience more warming than at low latitudes. For example, in winter the reduced area of sea ice and snow cover should have the amplifying effect for temperature rising over polar region. Thus the meridional temperature gradient would also be reduced, so as the baroclinicity. Baroclinicity is important in theories concerning synoptic weather forecast in mid-latitudes.
Is there an estimate, and if yes how much climate change will reduce synoptic weather predictability? How will predictability be affected in springtime for mid-latitudes?
