أثر تغير المناخ في عدد أيام بقاء المرتفعات الجوية الضحلة و العميقة فوق العراق للدورتين (1961-1950)‎ (2016-2005)‎

Abstract EN

This research conducted in the context of showing the impact of climate change in the number of days of permanence the air heights, with their shallow and deep classes, over Iraq that are represented by the Siberian high, the European high and the semi tropical high, whether in the case of deep extensions, secondary centers or shallow extensions for the two sessions (1961-1950) (2005-2016) within the pressure level (1000,850 mb) of the daytime observation ((GMT1200) for analyzing weather maps, while a comparative picture of the number of days that these heights remained over Iraq was drawn from the stations (Mosul, Baghdad, Basra).

The highlands have a clear impact on the weather and climate of Iraq, as they often work on reducing temperatures, clarity and air, and a decrease in the activity of the rising air currents as a result of the fall of air currents and that the increasing in the number of days of permanence of the heights is a result of climate change, which has become clear on the increasing in the rate of desertification, dust storms and the lack of green areas due to the low rates of precipitation of all kinds and other climatic conditions upon its control over Iraq.

It is noticeable in the climate cycle (1961-1950) that the number of days of permanence for secondary centers with shallow extensions increased in exchange for a decrease in the number of days of permanence of deep extensions for atmospheric heights such as the Siberian high, the European high and the subtropical high, while in the climate cycle (2005-2016) there was an increasing in the number of days of permanence for deep extensions against a decreasing in the number of days of permanence for secondary centers and shallow stretches.
