What does this research mean for the field?

Sea surface temperature anomalies in the tropical Pacific and Indian Oceans suppress autumn tropical cyclone genesis in the western North Pacific on interannual timescales, while warm anomalies in the midlatitude North Pacific inhibit it on decadal timescales. Novelty: ClaimNovelty.INCREMENTAL. Consensus alignment: ConsensusAlignment.NEUTRAL.

What question did this study set out to answer?

Climate modeling and reanalysis uncovers distinct sea surface temperature drivers of autumn cyclone genesis in the western North Pacific, suggesting pathways to improve seasonal forecasting.

Key Points

To determine the mechanisms through which tropical and midlatitude sea surface temperature anomalies influence autumn tropical cyclone genesis in the western North Pacific across interannual and decadal timescales.
Analyzed atmospheric and oceanic reanalysis datasets to evaluate interannual and decadal autumn tropical cyclone genesis in the western North Pacific.
Conducted numerical sensitivity experiments using atmospheric general circulation models forced with historical sea surface temperature anomalies.
On interannual timescales, El Niño-like sea surface temperature anomalies in the tropical Pacific and Indian Oceans suppress western North Pacific convection and induce anomalous subsidence via atmospheric wave responses, reducing cyclone genesis.
On decadal timescales, warm midlatitude North Pacific anomalies increase upward turbulent heat flux and weaken atmospheric baroclinicity, strengthening subtropical westerlies and vertical wind shear over the western North Pacific to inhibit storm formation.
Atmospheric general circulation model experiments forced with historical sea surface temperature anomalies successfully reproduce the observed circulation changes and tropical cyclone genesis suppression patterns.
