Implication

Partial regression analysis demonstrates distinct regional shifts in tropical cyclone genesis in the western North Pacific, highlighting limited direct impacts from North Atlantic warming.

Key Points

Western North Pacific tropical cyclone frequency displays marked regional shifts under El Niño Modoki, concentrating storm genesis across the southeastern basin.
From 1982 to 2022, warm North Indian Ocean sea surface temperature anomalies suppressed cyclone genesis in northwestern waters by weakening relative vorticity.
Partial regressions reveal that tropical North Atlantic warming induces negligible local circulation changes, highlighting its reliance on remote ocean basin pathways.
