Paleotempestología de la región caribeña: un estudio multi-proxy de la variabilidad espacial y temporal de la actividad de los huracanes en el Caribe en múltiples sitios

This executive summary describes a paleotempestology project led by Louisiana State University to analyze long-term hurricane activity in the pan-Caribbean region and the Pacific coast of Mexico. By utilizing multi-proxy data from lagoon sediments, stalagmites, tree rings, and corals, the research aims to understand the climatic mechanisms driving hurricane variability and assess future risks.

• A coral-based proxy record of Atlantic surface temperatures from AD 1552-1991 indicates that higher sea surface temperatures correlate with increased cyclonic activity, specifically before 1550 and after 1750, while cooler temperatures resulted in fewer Caribbean storms.
• Hurricane activity in the Caribbean is influenced by the Atlantic Multidecadal Oscillation (AMO) and the El Niño-Southern Oscillation (ENSO). Proxy data and models identify peaks in Atlantic hurricane activity during the Medieval period (AD 900-1100) and a resurgence starting in 1980, linked to La Niña conditions and higher sea surface temperatures.
• Proxy records from Belize and Nicaragua suggest an inverse phase relationship in hurricane landfalls between Central America, the Eastern Caribbean, and the east coast of the US. This indicates that the tropical anticyclone and the position of the Intertropical Convergence Zone (ITCZ) are significant factors in Western Atlantic coastal risks.
• The low-level jet (IALLJ) dominates air mass circulation in the Intra-American sea and critically affects moisture advection and sea surface temperatures, which are key drivers of storm damage and hurricane intensity.
• Demographic data from 2006 indicates that in the continental United States, approximately 19 million people live in vulnerable areas within 1 km of the coast, and 12 million live on coastal land less than 3 meters above sea level.
