1 Seasonal Distribution of Minimum Temperature over the Kingdom of Saudi Arabia

ABSTRACT: To examine the monthly and spatial variability of the minimum temperature over the Kingdom of Saudi Arabia (KSA), a set of data record of 57 years of monthly minimum temperature was used in this study. Climatologically values of mean minimum temperatures and their spatial variability were illustrated for the different seasons of the year. Then, significant regions in minimum temperature were described using yearly and monthly means minimum temperature. The study revealed the presence of a permanent thermal low of minimum temperature over water area in the Red Sea and thermal high of minimum temperature over land area in Al Rub-Al khali
