Multiple recent studies confirm that tropical and extratropical cyclones are exhibiting a poleward migration in their intensity and tracks, driven by factors such as tropical expansion, shifts in genesis locations, and broader climate warming.

The analysis

The claim states that poleward migration of cyclone intensity is driven by tropical expansion and other contributing factors. Papers [5], [6], and [8] directly investigate the poleward migration of tropical cyclones, identifying drivers such as shifts in genesis location, changes in the Hadley circulation (tropical expansion), and sea surface temperature patterns under global warming. No papers refute this mechanism.
