Firstly, the relationship between ENSO events and tropical cyclone activity was analyzed, and then statistical methods and numerical simulation models were used to analyze the effects of the two types of ENSO events on tropical cyclone activity.The results show that El Niño events help to enhance tropical cyclone activity in the Northwest Pacific, while La Niña events inhibit tropical cyclone activity in this region. In terms of seasonal modulation, El Niño events mainly have a positive impact on summer tropical cyclone activity in the Northwest Pacific, while La Niña has a negative impact on autumn tropical cyclone activity in this region.The results of this study have certain guiding significance for predicting tropical cyclone activity in the Northwest Pacific, and provide a theoretical basis for further research on the relationship between ENSO events and climate change.精品文档---下载后可任意编辑Keywords: ENSO events; tropical cyclone activity; seasonal modulation; Northwest Pacific
