الملخص EN

In this research has been analyzed data wind speed direction and the amount of solar radiation to measure the length of rough surface of the city of Hilla, a way that the logarithm of the wind and through monitoring of these data from the system meteorological installed on the surface of the earth up 22:00 in the faculty of education, science pure University of Babylon, south-westcity of Hilla, as well as the stability of the atmosphere have been calculated according to the method Basquil the specific period to perform the search from 01 / 01 / 2013 until 04/01/2013., the results showed that the average value of roughness length of the studied area of 0.5 m, so one of the semi-urban areas and has been through it a relationship along roughness with stability the air as high rate calculated ZH roughness elements in the area of research and calculate the length of the zero-offset Zd search area.
