在气候变化的情况下，预测估计，在未来30年内，极端热带气旋（TC）的频率将增加，在20°N和40°N之间的大西洋盆地，4级和5级飓风将增加两到三倍。近年来，加勒比海和大西洋盆地经历了几次极端TC，造成了广泛的人类，生态和经济损失[1]，[2]，[3]。为了更好地了解热带气旋及其在气候变化面前的潜在影响，有必要对过去的气候和现代热带气旋动态进行基于物理的了解。尽管众所周知的大西洋飓风季节，TC的水分和同位素不同的脉冲在地表和地下水库的传播同位素演变的地面观测缺乏。在这篇数据文章中，我们提供了飓风奥托（哥斯达黎加，2016年），内特（哥斯达黎加，2017年），伊尔玛（古巴和巴哈马，2017年），玛丽亚（古巴和巴哈马，2017年）和多里安（巴哈马，2019年）的地表降雨同位素组成（δ 18 O，δ 2 H和d过量）的新高频采样。这五个热带气旋的特点是在大陆和海洋登陆和过境期间产生了前所未有的影响。总共有161个表面降雨样本被收集在被动设备中[4]，具有基于事件和每日频率，导致迄今为止加勒比海和大西洋盆地的第一个表面同位素风暴学解剖。从TC衍生的降雨通常导致在一个地区从几个小时到几天内大量输入同位素不同的水，因此这种独特的同位素组成通过地表和浅层地下储层传播。我们的数据还包括春季（N=338）和地表水（N=334）同位素组成的影响后，飓风奥托和热带风暴内特在中部哥斯达黎加。由于该地区以其多样的降雨动力学和气候变化“热点”而闻名[5]，[6]，[7]，我们的数据提供了一个机会，可以根据气候强迫，TC降雨量和补给率，改进和补充现代和过去的气候解释，这些解释通常来自卫星产品和方解石-δ 18 O古气候档案。以及过去中美洲文明因气候变化而衰落的假设。
Under a changing climate, projections estimate that over the next thirty years, extreme Tropical Cyclones (TCs) will increase in frequency, with two to three times more Category 4 and 5 hurricanes in the Atlantic basin between 20°N and 40°N. In recent years, the Caribbean Sea and Atlantic Ocean basins have experienced several extreme TCs, resulting in extensive human, ecological, and economic damage [1], [2], [3]. To improve understanding of TCs and their potential impacts in the face of climate change, physically based understanding of past climate and modern TC dynamics is necessary. Despite the well-known Atlantic hurricane season, surface observations of the isotopic evolution of TC's moisture and the propagation of isotopically distinct pulses across surface and subsurface water reservoirs are lacking. In this data article, we provide novel high frequency sampling of surface rainfall isotope compositions (δ18O, δ2H, andd-excess in ‰) for Hurricanes Otto (Costa Rica, 2016), Nate (Costa Rica, 2017), Irma (Cuba and The Bahamas, 2017), Maria (Cuba and The Bahamas, 2017), and Dorian (The Bahamas, 2019). These five TCs were characterized by unprecedented impacts during continental and maritime landfalls and passages. In total, 161 surface rainfall samples were collected in passive devices [4] with event-based and daily frequencies, resulting in the first surface isotopic tempestology anatomy across the Caribbean Sea and Atlantic Ocean basins to date. Derived rainfall from TCs often results in large input amounts of isotopically distinct water over an area from few hours to several days, and therefore this unique isotope composition is propagated through surface and shallow subsurface reservoirs. Our data also include spring (N=338) and surface water (N=334) isotope compositions following the impact of Hurricane Otto and Tropical Storm Nate in central Costa Rica. As this region is well-known for its diverse rainfall dynamics and as a climate change ‘hot spot’ [5], [6], [7], our data provide an opportunity to improve and complement modern and past climate interpretations often derived from satellite products and calcite-δ18O paleoclimatic archives in light of climatic forcing, TC rainfall amounts and recharge rates, and the hypothesized climatic-induced decline of past Mesoamerican civilizations.
