On the Consumption of AgI Seeding Agent: Dependence on the Liquid Water Content in the Seeding Zone
AbstractA one-dimensional kinematic model of Lagrangian type is applied to investigate some hail suppression efficiency parameters dependence on the liquid water mixing ratio in the seeding zone. The silver iodide seeding agents are injected at the bottom of the seeding zone (a level of -8°C). Their interaction with cloud is simulated by a microphysical model. It calculates the maximum seeding agent mixing ratio at the bottom of the seeding zone needed to produce the critical number concentration of graupel at its top. This ratio is expressed through the number of hail rockets fired (N). The value of N strongly depends on the type of agent especially for lower values of liquid water mixing ratio.
