Abstract
- The rate of change in the marine environment over the eastern Agulhas Bank along the south coast of South Africa (32–37 ∘ S, 20–30 ∘ E) is studied using reanalysis observations for 1900–2015 and coupled ensemble model projections for 1980–2100. Outcomes are influenced by resolution and time span: ∼ 1 ∘ datasets covering the whole period capture large-scale changes, while ∼ 0.5 ∘ datasets in the satellite era better distinguish the cross-shelf gradients. Although sea surface temperatures offshore are warming rapidly (0.05 ∘ C yr -1 since 1980), a trend toward easterly winds and a locally stronger Agulhas Current have intensified nearshore upwelling (-0.03 ∘ C yr -1). The subtropical ridge is gradually moving poleward, leading to a drier climate. [ABSTRACT FROM AUTHOR]
