Which atmospheric effect amplifies seasonal temperature variation at higher mid-latitudes?

💡 Explanation

When temperature gradients increase poleward during winter, the meridional temperature gradient increases because of reduced solar influx which causes a stronger pressure gradient and faster winds aloft, amplifying the jet stream meandering effect. Therefore the variation increases owing to increased transport of masses of air, rather than subsidence, confinement, or precipitation effects which dampen temperature swings.
