Abstract : Climate variability and climate change, reflected by the remarkable increase in global surface temperature, constitute a reality that affects our daily life. The subject is also one of the hot topics, that is of particular interest to regional and global policy makers. Given that climatic conditions vary from one period to another and from one region to another, response strategies and adaptations to climate change, both at the regional and global levels, must address climate variability and change. Strategic decision, on regional and global levels, towards reducing the probable impact of future climate change can only be achieved through intensification of research studies in climate variability and change. Climate change has various aspects such as changes in the mean or variance. Adaptation strategies to, and efforts to mitigate the impacts of climate change need emphasize not only changes in the long-term mean weather attributes but also changes in the variance and other attributes of climate variables. The impact of changes in climate variance, for example, on human and natural systems is more important than that due to changes in mean climate. Surface temperature is an important climate variable that directly affects human health and crops, and is used to quantify climate change. The aim of the present project is to detect climate change signals over the Kingdom of Saudi Arabia (KSA) by studying and characterizing climate variability and identify any changes in climate using observed and reanalysis surface temperature. Temperature over KSA is expected to have complex structure due to the large extension from the vast area of the country and its pronounced relief. We will investigate daily and monthly, as well as interannual and interdecadal surface temperature variability over KSA. The study will focus on the temporal and spatial variation of high and low frequency surface temperature time series at different stations to characterize their spatio-temporal variability. The study will also use a time-frequency domain analysis to identify intermittent characteristics, e.g. oscillations, using wavelets. The gridded surface temperature data will be used to assess, correct and complete the missing values of the observed records, which will be used as a data base for further research studies of climate variability and climate change. This study will address possible relationships between surface temperature variability and the orography and soil texture of our area. Finally, the results will be utilized to obtain climatic classification of KSA, and to predict future behavior of surface temperature.
