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
Summary
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. The research utilizes proxy data from coastal lagoon sediments, stalagmites, tree-rings, and corals to understand the climate mechanisms driving hurricane variability and to assess future risks.
Key insights
- 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 storms in the Caribbean.
- Peaks in Atlantic hurricane activity occurred during the Medieval period (AD 900-1100) and again starting in 1980, driven by La Niña-like conditions and warmer sea surface temperatures. This activity is influenced by climate patterns including the El Niño-Southern Oscillation (ENSO) and the Atlantic Multidecadal Oscillation (AMO).
- Proxy records from Belize and Nicaragua suggest an anti-phase relationship in hurricane landfall activity between the eastern Caribbean and U.S. East coast versus Central America. This suggests that steering patterns, influenced by the subtropical anticyclone and the inter-tropical convergence zone (ITCZ), affect coastal risks in the western Atlantic.
- Analysis of the Low-Level Jet (IALLJ) in the Intra-Americas Sea shows it is a critical factor for storm damage and hurricane strength because it affects moisture advection and sea surface temperatures.
- Demographic data from 2006 indicates that in the conterminous U.S., approximately 19 million people live in vulnerable areas within 1 km of the coastline, and 12 million people live in coastal areas with an elevation of three meters or less.
