Abstract:

The location of Iraq is within the desert region of little amounts of rain. Its rainfall system is part of the Mediterranean rainfall system where the rainfall starts in October and ends finally in early June. The reduction of rainfall in Iraq is attributed to its location, hence, the topography plays an important role in the variance of rainfall in different locations of the country. In the topography of Iraq plain with no height the place discrepancy in the rainfall amount would be little as in the middle and the south regions where the rainfall discrepancy is very little. Thus, the northern region of Iraq is considered as rain oasis in desert region. It is important to determine the altitude contribution in the increase of rainfall. Although the climate studies approve the effect of altitude in increasing rainfall amount, the amount of this increase is different pursuant to the location and the climate of the region. Thus, it is necessary to determine the contribution of highlands in the amount of rainfall in Northern Iraq. The highland is distinguished by climate variance that effect on all the climate elements. The climate discrepancy in the mountain region take vertical not horizontal sample as occurs in the plain region. Thus, it is probable to find more than one climate region in one place of great height. When it is found the temperature takes one sample in its reduction with the altitude, the rainfall does not have this sample. Thus it required that each region is studied alone to search the sample of rainfall increase by the altitude of this region .
