Provided is a wind blow type ground-based cloud seeding material generator for weather modification, which is capable of perform an experiment for precipitation enhancement through the steps of burning cloud seeding flares on the ground, vertically and horizontally dispersing the seeding materials, and dispersing the seeding material to clouds or fog to grow water drops and ice crystals, and which makes experiment and management easy through effective vertical dispersion of cloud seeding materials.

Provided are a method and system of analyzing ingredients of an artificial rainfall for verification of a cloud seeding effect. As the method and system, which can verify an effect of the artificial rainfall in such a manner that a seeding material becomes different according to each temperature of clouds at a seeding altitude, water sampling from precipitation is performed before and after seeding, and thus the ingredients of a water sample are analyzed using each of a method of analyzing a heavy metal component and a method of analyzing a water-soluble ion component according to a cool cloud and a warm cloud so that whether or not there is a change in each concentration of the ingredients can be determined, are provided, an experiment for the artificial rainfall can more effectively be performed.
