North Indian Ocean Marine Heatwaves and Monsoon Rainfall Impacts, 1982–2024

27.2 MB PDF data sheet analyzing marine heatwave variability and drivers in the North Indian Ocean from 1982 to 2024. The dataset, authored by Ligin Joseph and shared under a CC-BY-4.0 license, uses detrended sea surface temperature anomalies and Empirical Orthogonal Function analysis to identify two leading modes of variability, explaining 22% and 8% of the variance respectively.

Use Cases

• Identify drivers of marine heatwaves based on associations with El Niño, La Niña, and the Monsoon Intraseasonal Oscillation described in the analysis.
• Model monsoon rainfall responses based on the distinct wet/dry patterns linked to the two primary modes of marine heatwave variability.
• Analyze the termination mechanisms of marine heatwaves based on described links to monsoon wind re-intensification and evaporation changes.

Strengths

• Analysis covers a 43-year time range from 1982 to 2024.
• Identifies two leading modes of variability with explained variance percentages of 22% and 8%.
• Data is openly shared under a CC-BY-4.0 license.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The primary file format is PDF, which may require extraction for computational analysis.
