Abstract
In recent years, Puerto Rico has been repeatedly hit by drought and hurricane, causing severe damage to the local society and economy. Therefore, understanding the region's climate variability and predicting extreme weather has become an important scientific problem. Cave stalagmites are widely recognized as high-quality terrestrial paleoclimate proxies due to their accurate dating and high resolution. In this study, we present a stalagmite-based multi-proxy reconstruction of hurricane and hydrological changes in Central America from the island of Isla de Mona, Puerto Rico, for the mid-Holocene period (4700–6260 a BP). Our data suggest a significant influence of solar activity on rainfall patterns in Central America via changes in the mean position of the Intertropical Convergence Zone (ITCZ). Our study further shows that El Niño may have played a role in influencing hurricane development at a decadal scale, and also found that the relationship of hurricane activities and El Niño intensity on the decadal and centennial scale is variable. The implications of our findings are crucial for informing contemporary climate models and enhancing our preparedness for potential future climate scenarios in the region.
近年来，波多黎各多次遭受干旱和飓风袭击，给当地社会和经济造成严重破坏。因此，了解该地区的气候变异性和预测极端天气已成为一个重要的科学问题。洞穴石笋因其精确的年代测定和高分辨率而被公认为高质量的陆地古气候代用指标。在本研究中，我们从波多黎各的莫纳岛（Isla de Mona）的石笋中获得了全新世中期（公元前 4700-6260 年）中美洲飓风和水文变化的多代理重建数据。我们的数据表明，太阳活动通过热带辐合带（ITCZ）平均位置的变化对中美洲的降雨模式产生了重大影响。我们的研究进一步表明，在十年尺度上，厄尔尼诺可能对飓风的发展起到了一定的影响作用，同时还发现，在十年和百年尺度上，飓风活动与厄尔尼诺强度之间的关系是多变的。我们的研究结果对于为当代气候模型提供信息和加强我们对该地区未来潜在气候情景的准备至关重要。
期刊介绍：
Marine Geology is the premier international journal on marine geological processes in the broadest sense. We seek papers that are comprehensive, interdisciplinary and synthetic that will be lasting contributions to the field. Although most papers are based on regional studies, they must demonstrate new findings of international significance. We accept papers on subjects as diverse as seafloor hydrothermal systems, beach dynamics, early diagenesis, microbiological studies in sediments, palaeoclimate studies and geophysical studies of the seabed. We encourage papers that address emerging new fields, for example the influence of anthropogenic processes on coastal/marine geology and coastal/marine geoarchaeology. We insist that the papers are concerned with the marine realm and that they deal with geology: with rocks, sediments, and physical and chemical processes affecting them. Papers should address scientific hypotheses: highly descriptive data compilations or papers that deal only with marine management and risk assessment should be submitted to other journals. Papers on laboratory or modelling studies must demonstrate direct relevance to marine processes or deposits. The primary criteria for acceptance of papers is that the science is of high quality, novel, significant, and of broad international interest.
