尽管飓风季已经开始,但今年大西洋盆地的热带气旋活动异常平静。这主要是因为太平洋地区出现了强烈的圣婴现象,导致海水温度创下历史新高。
这种异常温暖的海水改变了全球的高空气流模式,在大西洋上空形成了强烈的风切变。同时,来自非洲撒哈拉沙漠的干燥沙尘也进一步抑制了雷暴的发展。
虽然整体气候环境不利于风暴形成,导致今年的活跃度远低于平均水平,但专家警告沿海居民仍需保持警惕。历史经验表明,在圣婴年依然可能出现极具破坏性的强烈飓风。
Despite the official start of the hurricane season, tropical cyclone activity in the Atlantic basin has been unusually quiet this year. This is primarily due to a strong El Niño event in the Pacific, which has pushed sea surface temperatures to historic highs.
These abnormally warm waters alter global upper-level wind patterns, creating strong wind shear over the Atlantic. At the same time, dry and dusty air blowing from the Sahara Desert in Africa further suppresses the development of thunderstorms.
Although unfavorable climatic conditions have led to a season with well below average activity, experts warn coastal residents to remain vigilant. History shows that highly destructive and intense hurricanes can still occur during El Niño years.
