This work is inspired by the Lorenz-1984 model, and looks into hemispheric surface temperature gradients as diagnostic indicators of mid-latitude atmospheric circulation dynamics. The relationship between hemispheric temperature gradients, ENSO, and the location and strength of the Northern Hemisphere jet stream and storms is investigated in reanalysis and GCMs.
