Abstract
A correlation analysis of daily rainfall in the Jordan Valley has been undertaken, both within the Valley itself and in relation to the surrounding hilly areas in Israel and Jordan. Results show the climatic singularity of the Jordan Valley, concerning not only the well-known rain deficiency, but also a high degree of independence of rainfall in the Valley relative to the areas surrounding it. This independence is explained in terms of the timing of rain events and their localness. On the other hand, the abrupt and massive topography of the Valley does not affect even locally the orientation of cell movement.
