Data from recording raingages have been used to study dirunal variations of rainfall in three regions: Along the coast, in the southern coastal plain and in the Negev. Rainfall within various intensity intervals has been treated separately. Results have been used for inferences on local and regional factors that affect the precipitation process and control diurnal variations in it. Results show a strong afternoon and evening predominance of high-intensity rainfall in the Negev, resulting from surface heating. This factor has been found to be less effective in the coastal area, where the major concentration of high-intensity rainfall is between 21-03 around midnight. This has been ascribed to land-sea temperature differences, and to convergent flow that is characteristic to the nocturnal land breeze in that region.
