Abstract
Atmospheric Boundary Layer (ABL) height (h) is one of the basic criteria for describing its structure. ABL measurements, parameters and predictions have numerous practical and theoretical implementations as forecast of pollutant concentrations, surface temperature, expansion of disturbance measurements or in climate models and numerical weather prediction. The height of mixing layer is difficult to be measured; therefore, mathematical methods are introduced to calculate this layer and different FORTRAN programs have been developed to define the height of ABL on hourly basis per year. The analysis of the results showed that the variation of the height of the mixing layer for different seasons depends on the type of the dominant stability class and the value of wind speed, where the rise of the mixing layer in winter and autumn months may be referred to increased frequency of stability conditions in the unstable and slightly unstable atmosphere On the other hand, when the stable conditions are dominant, the height of the mixing layer remains smaller. The boundary layer ozone is a standard contaminant because of its harmful effects on living organisms and plants. It also has an active role in atmospheric chemistry and climate change; therefore, monthly and seasonal variation of the surface ozone O3 concentration and its effects on the atmospheric boundary layer measured for the first time at coastal site in Egypt at the period 2013.
