Spearman’s correlation coefficients for our meteorological variables.

To determine the strength of the relationship between each meteorological variable, we performed a series of non-parametric Spearman’s Rank Correlation ρ coefficients to measure their association. We performed the analyses covering four conditions: all periods, e.g., during months when no cases were reported, during months when cases were reported, and during months when deaths were reported as one dataset. While many of the variables had statistically significant relationships according to the p-value, those correlations’ strengths were weak, except for ATMP and WTMP, where a strong relationship was defined as one with a ρ of greater than 0.80.
