V. Artificial Rain

3. The effectiveness of artificial rain

According to the evaluation by meteorological researchers with years of experience in rainmaking, artificial rainmaking by long-term planning of ground silver iodide burning can on average increase precipitation by 10%; whereas using aerial artificial rainmaking, by spreading silver iodide to appropriate convective thunderstorm cells, can increase precipitation by 20%. However, the effectiveness of artificial rain is still influenced by complicated factors such as weather conditions in each region, implementation skills, and administrative coordination, and is therefore still uncertain in some areas.
