Abstract:
The current research aims to study(A study of the North and North eastern Winds and its Impact on some of the Elements and phenomena of Iraq Climate ) and to achieve this objective study adopted the descriptive approach and climatic conditions existing in the study area and their impact statement in determining the surface wind direction towards the north and north - east; Also follow the analytical approach by analyzing charts liturgical Al saatah to see a repeat depressions and elevations flanking the northern and north - eastern wind and see which ones cause the wind gusts, As well as follow a quantitative approach in dealing with climate data on the subject of research for the period ((from 1990 to2013.It was clear through the current study, there are several factors that Affect wind in the north and north - eastern, including direction of fixed factors, including the variable factors that affect recurrence in contrast spatially and temporally to the study area.The study showed that there are several systems caused the recurrence of Northern winds and north - eastern and the most important is the low Indian as cause blowing this wind by a large margin for being more repetition and the dominance of the study area in the summer, followed by the Siberian high in importance because it comes from the North - east and the north side East and cause the wind blowing this then Sudanese low, oualemrtf EU and semi - tropical and finally low - Mediterranean.The statistical analysis of time series data itself, show that there is a relationship between (0.874 - 0.03)direct correlation between the frequency and North wind temperaturesaccompanying her while a relationship between moral occurrences of North East wind and temperatures accompanying them did not appear. And it found that there is a relationship between moral northern winds recurrence rates and the relative humidity while the moral relationship between occurrences of northeast winds and relative humidity levels did not show , also found that there is a direct correlation between the occurrences of the north wind and dust spiraling ranged between (0.886 - 0.512) and the relationship is found between occurrences of wind north - eastern and dust spiraling The relationship between the occurrences of the north wind and dust stuck relationship moral ranged between (0.893 - 0.652), and no significant relationship between the occurrences of the north - eastern wind and dust stuck in most of the stations.Which indicates that at higher temperatures in summer increase with the north wind frequency and vice versa when they fall, either north wind East they increasingly Tkaradtha at lower temperatures and less at the height of that relationship is a moral emerged, while the relative humidity is not affected when you increase or decrease the occurrences North and north - eastern wind on the study area.As for the dust we note that it increases the rising cases of dust and stuck with a north wind that any recurrence of increased North wind recurrence increases ,with dust situations, and vice versa for the north - east wind , with increasing northeast winds repeat at least repeat dust cases
