−67 to −97% Mean Value (−76%)

−56 to −65% Mean Value (−60%)

  1. Poleward migration’s weakening impact is defined as: (trend slope of TC Move - trend slope of TC Stay)/trend slope of TC Stay, because TC Stay is the reference scenario.
  2. • For RCP 4.5, the weakening impact mean value is −30% (based on the 4 MMEs from C-Track-4.5).
  3. • For RCP 8.5, the weakening impact mean value is −68% (based on 8 MMEs, i.e., 4 MMEs each, from C-Track-8.5 and E-Track-8.5).
