Figure 3

Mean values of U, the east-west component of the wind vector, for several WRF cases, by month, by hour, and by site. The sites are shown in Figure 2(a). The colored lines in the key represent results from different WRF cases from the earliest and simplest at the end to the final at the beginning. The black line is the observed data.
