Figure 9. Steps used in computation of rainfall model. (A) Rainfall from recording stations in southwestern Florida was averaged and period of record monthly mean values were computed. The monthly deviation of rainfall from these mean values was computed (expressed as standard deviation above or below the normal monthly mean). A LOWESS smooth of these data was computed. A frequency analysis was performed on the resulting smoothed rainfall values, and the values below the (B) 5th percentile, (C) 10th percentile, (D) 15th percentile, and (E) 20th percentile were computed. The model of rainfall constructed in this way is in good agreement with the timing of droughts in the area.
