Abstract:
Among many other climatic elements, wind is the one of the most important ones for its an active role in specifying the nature of climatic features ; which consequently made it essential to study directions and velocity of wind both for meteorologists and climatologists as they cause a lot of weather changes such as those occurring to temperature, humidity and others. They - wind - lead, for instance, to rise temperature if they come from warm sides and decrease it in case they come from cold ones.If they were humid, they would cause rainfall over areas beneath and they also, in case of being speedy, cause dust storms of both kinds : sand and earthen ones.Wind affects many economical activities. They affect on determining the sites of industrial establishments and where its waste dumps should be located; on city construction and agriculture productivity along with exploiting wind in various fields such as using it in generating energy.The purpose of this research is to study directions and velocity of surface wind in Iraq as far as its differences in time and place between the southern, northern and middle zones, and the one zone stations are concerned.A 30 years climatic cycle (1961 - 1990) was chosen to the amount of 12 stations distributed in the country as follows : - Zakho , Kurkuk, Suliamaniya, and Mosel stations for northern region - Khnakeen, Ana , Alrutba and Baghdad stations for middle region. - Al - Hai , Al - Diwaniya, Al - Nassiriya and Basra stations for southern region.The research included three chapters. The first one dealt with affecting controls on directions and velocity of surface wind in Iraq. These controls were divided into stable ones : (locations as for latitude, topographic relief and water flats) and dynamic : (air pressure, air masses, weather fronts and weather highs and lows). The second chapter treated of wind ,directions in Iraq as to its differences in time and place according to circled - directions sectors. It was also possible to study the weather condition of the change of prevailing directions for chosen stations in the country. As for the third chapter, it was devoted to study the velocity of surface wind in Iraq and show its differences in time and place. It also studied the standard velocity registered in station during different years as well as the daily course of the velocity of surface wind in the stations of the study during January and July.In final, the research contained conclusions being reached through studying the subject of this research.
