تأثير ذبذبة شمال الأطلسي على معدل تكرار المنظومات الضغطية فوق العراق

Abstract EN

The study area is located within the southwestern part of the Asian continent, between two latitudes (29.05°, 37.23°) in the north The country has been divided into three regions : the northern region, which lies north of latitude 35 degrees north, And the central region bounded between latitudes 32°-35° north, and the southern region, which lies south of latitudes 32° north.

The study targeted one of the most important climate issues related to pressure oscillations, including the NAO oscillation, in order to know the effects of this oscillation on the frequency of pressure systems over Iraq.

The negative frequencies of the Siberian High rise, while when the vibration is at its positive pole, the frequencies of the subtropical high rise, while the Mediterranean depression increases in frequency with the negative side of the NAO oscillation.
