El Niño Onset Time Affects the Intensity of Landfalling Tropical Cyclones in China

In this work, we studied the influence of spring (SP) and summer (SU) El Niño events on landfalling tropical cyclones (TCs) in China. The results showed that compared to SU years, average latitude TCs SP years shifted significantly southward TC intensity was stronger, especially post-landfall period. Additionally, more severe storm-level generated over South China Sea made landfall Meanwhile, southern had a greater intensity, but eastern were opposite. These changes during could be attributed favorable dynamical thermodynamical conditions, which are beneficial for maintaining duration after landfall. have important implications an in-depth understanding activities, as well disaster prevention mitigation.
