Abstract: Rainfall in Iraq is characterized by unorganized distribution of both spatial and temporal. The annual, seasonal and monthly mean rainfall varies considerly with years. The recorded rainfall quantity in the different meteorological stations varies from location to another according to sea surface elevation and the geographical position of meteorological stations.
Variation of rainfall with space and time were studied in Iraq for the period (1980-2010) using 22 meteorological stations. Mean monthly, seasonally and annually values of rainfall were found in different meteorological stations. Winter months represent about (42-56) % of total annual rainfall. The annual variability of rainfall in all these stations is high. Isohyetal method was used to estimate the mean monthly values of rainfall in Iraq. Simple and Multiple Regression Equations were found in Mosul, Baghdad and Basrah stations between rainfall and different meteorological elements.
