Diurnal Distibution of Convective Wind Observations by Months

   This figure shows a flatter overall diurnal distribution and a 20 UTC maximum than the seasonal mean.
Figure 10a. A 24-hour percentage distribution of all convective wind observations for all the convective periods which occurred during the month of May over the 18-year study period.



   The afternoon peak becomes stronger as the thermal forcing increases.
Figure 10b. A 24-hour percentage distribution of all convective wind observations for all the convective periods which occurred during the month of June over the 18-year study period.



   The afternoon peak reaches its maximum during July with some of the strongest daytime heating of the year.
Figure 10c. A 24-hour percentage distribution of all convective wind observations for all the convective periods which occurred during the month of July over the 18-year study period.



   The afternoon maximum drops off a bit from July.
Figure 10d. A 24-hour percentage distribution of all convective wind observations for all the convective periods which occurred during the month of August over the 18-year study period.



   The distribution flattens considerably with a much greater frequency of nighttime/early morning events and slightly later peak at 20 UTC like May.
