The above skewness analyses reflect shifts in seasonal rainfall and temperature during periods consistent with strong and moderate La Niña conditions; i.e., the 14 summer periods listed above were marked by average S Index values below the first and coldest sextile of 1895-1997 values. Shaded climate divisions indicate areas that experienced a significant incidence of above or below median seasonal climate. Confidence levels for skewness can be found under the Above Median colorscale legend. Where climate divisions are annotated, significant skewness in the highest or lowest 25% of the historical distribution was found, with (n/m) indicating n seasons in the first 25%, m seasons in the fourth 25%.
