Auxiliary material for this article contains tables and figures relating to the historical data set used for statistical analysis, and part of statistical analysis results, including bootstrap analysis to determine the robustness of regression and correlation analysis to find the maximum correlation between the hypoxic area and duration of westerly wind.
