Paleotempestologia de la region caribena: un estudio multi-proxy de la variabilidad espacial y temporal de la actividad de los huracanes en el caribe en multiples sitios

The project utilizes paleotempestology—analyzing coastal lagoon sediments, stalagmites, tree-rings, and corals—to reconstruct past hurricane activity in the Caribbean and Mexico. Key findings link increased hurricane activity to warmer sea surface temperatures and specific climate patterns like the Atlantic Multidecadal Oscillation (AMO) and El Niño-Southern Oscillation (ENSO). The research identifies peaks in activity during the Medieval period (AD 900-1100) and since 1980, while also noting an anti-phase relationship in landfall activity between Central America and the eastern Caribbean/U.S. East coast. Additionally, the study assesses coastal vulnerability in the U.S., noting millions of people live in low-elevation areas.

• A coral-based proxy record of Atlantic sea surface temperatures from AD 1552-1991 indicates that warmer sea surfaces coincide with higher hurricane activity, specifically before 1550 and after 1750, while cooler surfaces correlate with fewer Caribbean storms.
• Hurricane activity in the Caribbean is influenced by the Atlantic Multidecadal Oscillation (AMO) and El Niño-Southern Oscillation (ENSO), with peaks occurring during the Medieval period (AD 900-1100) and from 1980 onwards, driven by warmer sea surface temperatures and La Niña-like conditions.
• Proxy records from Belize and Nicaragua suggest an anti-phase relationship in hurricane landfalls between Central America and the U.S. East coast/eastern Caribbean, likely caused by changes in steering patterns and the positions of the subtropical anticyclone and the inter-tropical convergence zone (ITCZ).
• Analysis of the Low-Level Jet (IALLJ) in the Intra-Americas Sea shows it significantly impacts moisture advection and sea surface temperatures, which are critical for the strength and damage of hurricanes.
• Demographic data from 2006 indicate that in the conterminous U.S., approximately 19 million people reside in vulnerable areas within 1 km of the coast, and 12 million live in areas with an elevation of three meters or less.
