Abstract：In view of the climate change mainly due to global warming,this paper used the data of tropi-cal cyclones landing in China from 1953 to 2022 to discuss the spatio-temporal evolution and disaster mechanism of tropical cyclones landing in China from El Niño/La Niña events,eastern and central El Niño/La Niña events.The results showed that:(1)The landfall tropical cyclones were significantly correlated with the SST in the regions of Niño index,and with the SST anomalies in the regions of Niño index 3.4 and Niño index 4,but no correlation with the SST anomalies in the regions of the Niño index 3 and the regions of the Niño 1+2 index;(2)The number of landfall tropical cyclones in the El Niño e-vent was small and the intensity was strong,while the La Niña event was opposite;(3)The number and intensity of tropical cyclones landing during the eastern type El Niño event was stronger than that of the central type El Niño event,and the number of tropical cyclones landing during the eastern type La Niña event was higher than that of the central type La Niña event,but the intensity was weaker than that of the central type La Niña event.This study provides some reference for forecasting and preven-tion of tropical cyclones landing in China at a long-time scale.
