AB  - In 1904, Prandtl represented the concept of boundary layer, boundary layer of atmosphere is called
to the area of atmosphere that is located just after Earth’s surface in which great turbulence is observed in
vertical transfer of heat, humidity and air displacement than troposphere. Air flow higher than earth’s surface
can be as thin and turbulent layers. Since, horizontal wind velocity on the surface is zero, velocity is increasing
by altitude immediately. In thin (non-turbulent) layers of flow, no considerable mixing is performed in slide
layers of air. Mixing heat, steam and moving inside boundary layer, creates a separated effect on vertical profile
of temperature, steam and wind velocity. In the layers close to earth’s surface, turbulence of heat, humidity and
movement are under the influence of their distance from surface elements like stones, plants and corns. Near
to sea shore, there is a cold boundary layer, its depth is changing during day, strong weather inversion
separates cold sea boundary layer and above hot weather. In the average distance of 60 km from shore, there
is a strong daytime signal in relation with heating and cooling of surface. Also, weak inversion between
825-850 m bar can be observed. In farthest distances from shore about 130 km, the depth of boundary layer is
high during day and no sign of inversion exists. Therefore, an upstream ocean cold flow can have great impact
on the structure of boundary layer.
