Due to the impact of global climate change, extreme weather events have become more frequent in recent years, with a corresponding increase in both the frequency and intensity of typhoons. As typhoons have extremely strong destructive power, they can have a significant impact on economic and social development, human life and property, as well as maritime activities. Therefore, the real-time tracking and positioning of typhoons is critical for mitigating their adverse impacts. Based on the infrared cloud image data from the multi-channel scanning imaging radiometer aboard the Fengyun-4 geostationary satellite, combined with the tropical cyclone best track dataset, this study uses the YOLOv8 object detection algorithm to achieve automatic identification and rapid positioning of typhoons. The verification results show that the recognition accuracy for typhoons with strong tropical storm intensity and above exceeds 83%, with a precision rate of over 88%. This achievement provides robust data support for maritime activities, maritime transportation, and oceanographic research, effectively improving the accuracy and timeliness of typhoon monitoring and enhancing safety in related fields.
