Abstract
He weather in many parts of the Middle East is effect by the topography, geographic location especially the subtropical regions, which located between 10{u00B0} to 21{u00B0} south and north. These areas are rarely affected by the synoptic situations approaching from the middle latitude while the local effects are the main feature that affects the weather directly and indirectly. The major finding of this work can be summarized in the following: 1. The desert climate should make use of the given conditions available for weather modification. 2. In the summer, a high percentage of the experimental seeding cases were actually suitable for seeding. Convective clouds with sufficiently warm bases, narrow droplet distributions, and cold cloud tops occur regularly during this season. The summaries and case studies support these generalizations. In order to conduct an evaluation of cloud seeding using a randomized experimental design, a large number of samples are needed. Radar statistics suggest that summer convection occurs frequently enough to produce enough candidate storms for statistical analysis in a 2-3 year program of randomized seeding. This assumes that such a program would include neighboring oman. Clearly, the summer season presents the best and most opportunities for seeding
