Abstract
:
In southwest of Saudi Arabia, precipitation is characterized by variability in space and time. The 21 years records for sixty-three precipitation stations were examined for their relationship to elevation and geographic locations. These stations were selected for the best spatial coverage, and unique and well represent different climate conditions. The study shows that annual precipitation is moderately correlated with elevation and it does not always occur at high elevation. Topographic feature, distance from the source of moisture and seasonality are also important factors for precipitation occurrence at different location in different times within the study area. According to these factors the study area has been divided into three subregions named Tihamah, Plateau and Mountain. The study showed that it is very important to incorporate the geographical features and seasonal changes to understand the variability of precipitation with elevation due to interaction between different sources of moisture.
