الملخص EN

The study presents the analysis of the impact of major climatic phenomenon called The Indian Ocean Dipole (IOD) on rainfall of Qassim region located in central of Saudi Arabia.

This study relies on rainfall data analysis for the period from 1981 to 2011.

Pearson's correlation method has been used to reveal the vulnerability of Qassim rainfall affected by IOD.

Statistical test results have shown that there is no correlation between annual rainfall and the IOD, which means that the impact of this factor does not appear on the annual rainfall.

Also, the correlation between the rain and the IOD is not statistically significant during the rainy season in four stations (Buraydah, Unaizah , Kra'a Al Marw and Oqla Sgor .

While, the rainfall of Prince Naif Airport, Alrass and Al Mithnab are relatively effected by the IOD.
