Reconstruction of SE trade-wind intensity based on sea-surface
temperature gradients in the Southeast Atlantic over the last 25 kyr.
Geophys. Res. Lett., 30(22), 2144, doi:10.1029/2003GL017557.
A prominent feature in the Southeast Atlantic is the Angola-Benguela
Front (ABF), the convergence between warm tropical and cold subtropical
upwelled waters. At present, the sea-surface temperature (SST) gradient
across the ABF and its position are influenced by the strength of
southeasterly (SE) trade winds. Here, we present a record of changes
in the ABF SST gradient over the last 25 kyr. Variations in this SST
contrast indicate that periods of strengthened SE trade-wind intensity
occurred during the Last Glacial Maximum, the Younger Dryas, and the
Mid to Late Holocene, while Heinrich Event 1, the early part of the
Bølling-Allerød, and the Early Holocene were periods of weakened
SE trade-winds.
STUDY NOTES: Alkenone sea-surface temperature (SST) estimates for the past 33 kyr
from a sediment core located near the modern Angola-Benguela Front.
