台风“蝴蝶”来袭 为何今年第1号台风“姗姗来迟”？

Core Viewpoint - The first typhoon of the year, "Butterfly," has formed later than usual, with implications for both risks and benefits in affected regions [1][2] Group 1: Typhoon Formation and Characteristics - Typhoon "Butterfly" formed on June 11 and is expected to make landfall in Hainan Island on June 13, moving towards Guangdong and Guangxi thereafter [1] - Historically, the average formation date for the first typhoon is March 25, indicating that this year's formation is over two months late [1] - The delay in typhoon formation is attributed to a larger and stronger subtropical high-pressure system, which has suppressed the necessary tropical convection for typhoon development [1] Group 2: Impacts and Preparedness - The late arrival of the typhoon may reduce the risk of compounded disasters from earlier typhoons, benefiting agricultural stability and fishing operations [2] - However, Typhoon "Butterfly" is predicted to make landfall as a strong tropical storm, bringing significant rainfall to Guangdong from June 13 to 15, with potential for heavy to extreme rainfall in various regions [2] - Local authorities in Hainan, Guangdong, and Guangxi are actively preparing for the typhoon, ensuring safety measures for maritime activities and coastal tourism [2]
