Future Projections of Multiple Tropical Cyclone Events in the Northern Hemisphere in the CMIP6‐HighResMIP Models

How future multiple tropical cyclone events (MTCEs) could change is crucial for effective risk management and ensuring human safety, however, it remains unclear. This study projects changes in MTCEs by 2050 the major basins of Northern Hemisphere using high-resolution climate models. Results show a significant increase frequency duration over North Atlantic (NA), notable decrease western Pacific (WNP), little eastern (ENP). The NA concentrated August–September, while WNP occurs most months. In contrast, ENP exhibits large yet insignificant seasonal variation, suggesting considerable uncertainty this basin. Further analysis shows that mid-level vertical motion dominates MTCE WNP, wind shear contributes to NA, which may be linked convection.
