Abstract
1 - Iraq is exposed to the movement of the waves when the wind straight weakens the impact of polar and tropical influences higher, resulting from lack of heat exchange between the two regions. 2 - a few occurrences of the waves wind straight over Iraq throughout the year for both Alrsdtan, reaching Madelhma 10.12 again in Alrsdh (00) and 8.09 again in Alrsdh (012), and this is due to the location of Iraq in the transition zone in which the repetition of the waves straight over it a little, so as to exposure to several types of extreme weather and high surface during the year. 3 - increase frequency waves air straight over Iraq in Alrsdh (00) during the months of Maes and March and September and April and October and November, rates were (1.72, 1, 1, 0.90, 0.81, 0.81) again, respectively, and accounted for 17% in May and 9.8% in March and 9.9% in September and 8.9% in April and 8% for each of October and the second, and returns the increase in this time of year that the waves wind during the swing between the shallow and Altstah, and between being a deep and effective, which make way to increase the air waves straight. and less iterations Alrsdh (00) recorded in the month of August and 0.45 again by 4.4%, to rush tropical air from the south that led to the control of tropical systems (aerobic indentations) over Iraq. 4 - occupied the month Mays ranked first in the frequency waves wind straight in Alrsdh (012) repeatedly hit 1.45 again to form a rate of 17.9%, comes the month of September came in second 0.90 again at a rate of 11.12%, then the months of March and April and October, which amounted FEEDING FREQUENCIES 0.72 and by 8.9 % for each of them. and less than occurrences in the observations of day (012) recorded during the months of December and January and August amounted to 0.36 and by 4.4% each, so as to clearly state variation warming in the months of December and January, which led to the grooves wind is the dominant level Pressure 500 mb, while the indentations are clearly the most air in the month of August at this level. 5 - characterized by waves aerobic low number of days of its control over Iraq, they do not exceed 15.54 days during the study period, and this was clear from the lack FEEDING FREQUENCIES, as waves can not be deepened in areas characterized by the status of diversity in the passage of weather events, but this is often limited balances appear on one, and may extend to monitor the fig a day. 6 - Maes is a month more months in the number of days as the frequency at a rate of 3.18 days for a rate of 20.46%, marking a big difference between him and the month of August, which does not exceed the number of days of repeated 0.54 days and the lowest rate was 3.47%.
