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

The project utilizes paleotempestology—analyzing sediment cores from lagoons, stalagmite isotopic records, tree rings, and corals—to reconstruct past tropical cyclone activity. Key findings indicate that higher sea surface temperatures in the Atlantic correlate with increased hurricane activity, with notable peaks during the Medieval Warm Period (AD 900-1100) and since 1980. The research also identifies an inverse phase relationship in hurricane landfalls between Central America, the Eastern Caribbean, and the US East Coast, suggesting that the Intertropical Convergence Zone (ITCZ) and tropical anticyclones are critical drivers of coastal risk. Additionally, the study expanded its scope to the Pacific coast of Mexico, identifying an extreme event in Baja California Sur approximately 500 years ago.

• A coral-based proxy record of Atlantic sea surface temperatures from AD 1552 to 1991 demonstrates that periods of higher hurricane activity before 1550 and after 1750 coincide with higher sea surface temperatures, while cooler temperatures correlate with fewer storms in the Caribbean.
• Hurricane activity in the Caribbean is influenced by the Atlantic Multidecadal Oscillation (AMO) and the El Niño-Southern Oscillation (ENSO), with peaks in activity occurring during the Medieval Warm Period (AD 900-1100) and again starting in 1980, linked to higher sea surface temperatures and La Niña-like conditions.
• Proxy records from Belize and Nicaragua suggest an inverse phase relationship in hurricane landfalls between Central America, the Eastern Caribbean, and the US East Coast, indicating that the position of the Intertropical Convergence Zone (ITCZ) and the tropical anticyclone 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 sea surface temperature and moisture advection, which are key factors for hurricane intensity and storm damage.
• Sedimentary evidence from Laguna La Poza in Baja California Sur, Mexico, indicates an extreme event occurred approximately 500 years ago.
