atmospheric stability is very important parameter because is ruled the dissipation of air, in this study modern device depend on sound wave used to measure atmospheric stability by Monin-Abukhov length (L) and scaling parameter z/L over Baghdad city at summer season months.
This parameter z-zd/L need to estimated topographic surface by morphometric analysis to obtain zero plane displacement (zd=10.4m) and roughness length (zo=1.4m) from domain wind direction (from North to South at this study).
At this study 2640 run done, 79% unstable, 12.6% neutral, and 8.3% stable, there is also subdivision for these results in cases unstable and stable condition to very and slightly.
Classification is also done at daytime and nighttime, where the rates for unstable at daytime and nighttime is high and nearly have small difference, but in neutral and stable there is clear difference.
Similarity function and scaling parameter from monin-Abu khov theory is calculated to test the turbulent and also can be comported with previous studies such as Businger and atmospheric stability is very important parameter because is ruled the dissipation of air, in this study modern device depend on sound wave used to measure atmospheric stability by Monin-Abukhov length (L) and scaling parameter z/L over Baghdad city at summer season months.
