دانلود کتاب American Society of Civil Engineers standard practice for the design and operation of hail suppression projects

''EWRI/ASCE 39-03'' provides useful information for implementing operational hail suppression activities, and provides information on the successful design, conduct, and evaluation of such efforts. Because the effects for seeding clouds for hail suppression on a storm's rainfall are not fully understood, a number of hail suppression concepts have been formulated. The five concepts most commonly employed in the context of operational hail suppression projects are included in this book: Beneficial Competition, Early Rainout, Trajectory Lowering, Promotion of Coalescence, and Dynamic Effects. The standard provides the best scientific and technical knowledge currently available on hail suppression to ascribe a process through which hail suppression should be designed, organized, and conducted to optimize the likelihood of success
