Comparisons between M2-LES configuration and M2 configuration within the D05 are shown in Table 8 and Figure 5 [right]. Even though M2 (D05) improved most metrics for all the meteorological parameters, there are not conclusive differences between them and this is an interesting outcome as it would allow us to apply WRF-LES approach to forecast air quality at an urban scale without deteriorating the quality of results. Figure 6 displays a wind flow comparison between M2 (D05) and M2-LES. This figure shows that by increasing reso area at a higher resolution.
