Study of the change in the number of days of the stay of the Siberian high air over Kirkuk station for the climatic cycle (2011-2022)

Abstract

    The research takes place in the context of showing the change in the number of days of survival of the Siberian high air a Kirkuk station represented by the climatic cycle (2010-2021), and the total and monthly average of the number of days of survival of the air heights and the amount of their changes, and the period that the pressure system takes over the Kirkuk governorate, have been analyzed, and it varies according to the difference of the system, its strength, and competition other systems for the level (1000) in millibars for the two observations (GMT) (00z) and (12z) for the Kirkuk station, whether the amount of change was in the positive direction of the rise or the decrease in the negative direction. Highlands have a clear effect on the weather and climate of Iraq, as they often work to reduce temperatures, clearness of the air, and a lack of activity in rising air currents as a result of the decline in air currents and the lack of green areas due to the low rates of rainfall of all kinds and other climatic conditions when they control over Iraq. It is noted in the climatic cycle (2010-2021) an increase in the number of days of survival of extensions and a decrease in the number of days of survival of secondary centers of the Siberian Highlands.
