<br />OROGRAPHIC CLOUD SEEDING <br /> <br />OBJ ECTIVE: Increase the number of snow crystals in naturally <br />deficient clouds in order that all available cloud <br />water will be utilized to grow the crystals. These <br />will fall to the ground thus depositing most of the <br />cloud water. <br /> <br />METHOD: 1. Silver iodide is released from one or <br />more generators located on the upwind <br />side of the mountain range. <br /> <br />2. Silver iodide particles transform many <br />of supercooled cloud droplets into <br />ice crystals. <br /> <br />3. Ice crystals attract moisture from <br />surrounding droplets and grow large <br />enough to fall to the ground as snow. <br />
