摘要

Abnormal weatherconditions and extreme weather existed over the Kingdom Saudi Arabia (KSA) throughthe last decades. The present paper investigates the relationship between the OceanicNino Index (ONI) and variability of surface air temperature and precipitation rateover KSA through the period from 1950 to 2015 year. The NCEP/NCAR Reanalysis ofmonthly data sets of the mean surface air temperature and precipitation rate forthe domain of the KSA is used. In addition, El Nino3.4 monthly data through theperiod (1950-2015) are used. For that period, the data set of the three months movingaverage of Nino3.4 anomaly, Oceanic Nino index (ONI), is used and analyzed. Thetime series, anomaly and correlation coefficient techniques are used to analyzethe data sets through the present study. The results revealed that the KSA climateparameters, temperature and precipitation rates are controlled by ONI mainly inthe autumn and winter seasons.
