Spatial and temporal variation of rainfall amounts in Iraq for the period (1956-2016 )

Abstract

The study aims at studying and analysing the spatio-temporal variation of the levels of rainfall in Iraq. Generally speaking, rainfalls in Iraq are characterised as irregular with diversified amounts and intensities around years and regions. The rainfalls in Iraq are associated with the arrival of three depressions which are: Mediterranean depression, Sudanese depression, and integrated depression. These depressions arrive Iraq with the end of September with few iterations, then they increase in October and peak in December, January, and February. After that they start decreasing in April and May. Therefore, it has been noted that rainfalls in Iraq peaks in the three months (December, January, and February) as the amounts increases obviously
