An overview of chad rain enhancement. the open (cloud seeding operation) project

In this paper we try to emphasize the effect of cumulus congestus cloud seeding in sahelian zone, using hygroscopic salts. For this purpose we first studied the climatic variability and impact on agricultural sector, livestock and water. Furthermore, we made a review of cloud seeding experiences abroad, then we studied the OPEN (Cloud Seeding Operations) project, from the point of view of its management, the performed activities and the perspectives of collaboration with other universities.
