Recent poleward shift of tropical cyclone formation linked to Hadley cell expansion

Recent research indicates that the annual-mean locations of tropical cyclones have migrated toward higher latitudes. Concurrently, an anthropogenically forced tropical expansion has been observed, yet the connection between the two processes remains little-explored. Here, using observational and reanalysis data, we investigate how large-scale dynamical effects, combined with coherent changes in the regional Hadley circulation, explain recent...
