The destruction wrought by North Atlantic hurricanes in 2004 and 2005 dramatically emphasizes the need for better understanding of tropical cyclone activity apart from the records provided by meteorological data and historical documentation. We present a 220-year record of oxygen isotope values of alpha-cellulose in longleaf pine tree rings that preserves anomalously low isotope values in the latewood portion of the ring in years corresponding with known 19th and 20th century landfalling/near-coastal tropical storms and hurricanes. Our results suggest the potential for a tree-ring oxygen isotope proxy record of tropical cyclone occurrence extending back many centuries based on remnant pine wood from protected areas in the southeastern U.S.
2004年和2005年北大西洋飓风造成的破坏极大地凸显了除气象数据和历史文献记录之外，更好地了解热带气旋活动的必要性。我们展示了长叶松年轮中α-纤维素氧同位素值的220年记录，该记录显示，在与已知的19世纪和20世纪登陆/近岸热带风暴和飓风相对应的年份里，年轮晚材部分的同位素值异常低。我们的研究结果表明，基于美国东南部保护区的残留松木，有可能建立一个可追溯到多个世纪以前的热带气旋发生的树木年轮氧同位素代用记录。
