科学家通过分析近30年的飓风数据,识别出了四个关键征兆表明倾斜的热带气旋正在竖直排列并准备快速增强。1研究基于1997年至2024年间28个飓风季的1510份雷达分析,由迈阿密大学罗森斯蒂尔学院和美国国家海洋和大气管理局共同完成,相关成果已发表在《地球物理研究期刊:大气圈》上。1
这四个预警征兆分别为:近地面形成紧密组织的环流、风切变相对位置有利、出现强上升气流和大范围降雨,以及存在温暖海水、高大气湿度和中层大气风弱的环境条件。1研究人员指出,提前一天发现这些组织化迹象,可以为沿海社区争取额外的疏散准备时间。1
Researchers from the University of Miami's Rosenstiel School and the National Oceanic and Atmospheric Administration have identified four key warning signs that indicate a tilted tropical cyclone is becoming vertically aligned and preparing for rapid intensification 1. The findings, based on nearly three decades of hurricane hunter data, could help meteorologists provide coastal communities with additional time to prepare for evacuation 1.
The study analyzed 1,510 radar observations collected between 1997 and 2024 across 28 hurricane seasons 1. The four critical indicators of storm organization include tightly organized low-level circulation, a favorable tilt position relative to wind shear, strong updrafts coupled with widespread rainfall, and environmental conditions featuring warm ocean waters, high atmospheric moisture, and weak mid-level winds 1. When meteorologists detect these organizational signatures a day in advance, it provides coastal residents with valuable extra preparation time before a storm strengthens significantly 1.
The research was published in the Journal of Geophysical Research: Atmospheres (DOI: 10.1029/2025JD045986) 1.
