1-5月“零台风” 今年北半球台风集体“迟到” 有哪些影响？

Group 1 - The core point of the article highlights that as of the end of May, no tropical cyclones have formed in the Northwest Pacific, marking a rare occurrence in the past 76 years, potentially becoming the seventh year with a "zero typhoon" start from January to May [1][3] - Historical statistics indicate that the average formation date for the first typhoon is March 25, and this year is over two months late [3] - The absence of tropical cyclones in the Northern Hemisphere, including the North Indian Ocean and North Atlantic, is noted, with only the Northeast Pacific generating its first tropical cyclone on May 29 [3] Group 2 - The delay in typhoon formation has both positive and potential negative implications [4] - Positively, the late arrival of typhoons can reduce the risk of disaster overlap caused by frequent typhoons, benefiting agricultural stability and safety in fishing operations [5] - Conversely, the lack of typhoons can exacerbate drought conditions, as they typically bring much-needed rainfall, and their absence may lead to increased agricultural pest issues and higher management costs [5]
