Coastal Wind Variability and Upwelling Impact in the Humboldt Current

Wind-driven coastal upwelling in the Humboldt Current System off Chile is exceptionally narrow compared to other eastern boundary systems. The dataset examines the impact of coastal wind variability and pressure gradients on the temporal and spatial distribution of these upwelling events. It was produced by the organization SCIOPS and sourced from NASA's Earthdata platform.

Use Cases

• Analyzing the relationship between equatorward wind stress and offshore surface Ekman transport.
• Modeling the interaction of coastal-trapped waves with wind-stress differentials along the Chilean coast.
• Investigating the intensification of upwelling events around westward-protruding capes and their connection to the poleward undercurrent.
• Studying the role of cyclonic wind-stress curl in cross-shore direction on upwelling enhancement.

Strengths

• Focuses on the distinctively narrow upwelling band of the Humboldt Current System.
• Examines multiple atmospheric drivers including mid-latitude frontal disturbances and coastal lows.

Limitations

• Specific data volume, temporal coverage, and spatial resolution are unknown.
• The absence of column names or sample data limits immediate assessment of data structure.
