Correlation between AOD and wind properties. (a) Variations of the daily AOD correlate with the northerly and southerly wind conditions, and (b) easterly and westerly wind conditions, separated by four levels of wind intensity: breezeless (0–5 knots), weak (5–10 knots), medium (10–15 knots), and strong (>15 knots). The dotted line is the exponential fit of the averaged WV - AOD scatter plot.
