Spatial and temporal analysis of climatological data in Jordan

This paper evaluates climate variability over Jordan by considering temporal and spatial variations on the basis of annual and seasonal meteorological variables including precipitation, relative humidity (RH), maximum and minimum temperatures over 30 years (1971-2000) at 16 representative observation stations over the whole country. The assessments are based on the statistical parameters such as the averages, coefficient of variation and skewness (SK). These parameters are mapped through the Kriging regional variability approach. Seasonal and annual parameter maps are presented and the climate variability interpretations are derived for the purpose of identifying climatologically homogenous precipitation regions. Climatic regions, temperature and humidity regimes, aridity and drought conditions in the country are determined, and the country is divided into three homogeneous precipitation regions.
