WHAT IS CLOUD SEEDING? 

​

Cloud seeding is a weather modification technique aimed at enhancing precipitation. It involves introducing substances like silver iodide, sodium chloride, or potassium iodide into clouds to encourage droplet formation and stimulate rainfall or snowfall. The process is used to improve water supply, reduce the severity of droughts, or dissipate fog. Cloud seeding can be conducted via aircraft or ground-based generators, and its effectiveness varies depending on atmospheric conditions

​​

The amount of Silver Iodide required for cloud seeding depends on various factors such as the size of the area targeted, the density of the clouds, and the specific seeding technique used. Generally, for cloud seeding operations, quantities typically range from a few grams to several kilograms of Silver Iodide per seeding event.

​

Typical dosage: 

•    In practical applications, around 0.1 to 1 gram of Silver Iodide is dispersed into the clouds per mission, often released from aircraft or ground-based generators. 

•    For larger operations or to seed extensive cloud systems, several kilograms may be used during a seeding campaign.

​

Key considerations: 

•    The goal is to introduce enough Silver Iodide particles to promote nucleation of ice crystals without excessive use, which is both economical and environmentally conscious. 

•    Precise quantities are usually calculated based on atmospheric data and the size of the cloud system.

​

​

1. Understanding Cloud Macrostructure

• Cloud type: Ice nucleation efficiency depends heavily on cloud type (cumulus, stratus, or towering convective clouds).

• Cloud top temperature: Silver Iodide is most effective in temperatures between -5°C and -20°C, where ice nucleation is favored.

​

2. Typical Silver Iodide Dosage

• Aircraft seeding: Approximately 0.05 to 0.2 grams of AgI per cubic kilometer of cloud.

• Ground-based seeding: Dosed via smoke generators or generators, often in the range of 1 to 10 grams per hour, depending on the cloud coverage and wind conditions.

​

3. Calculating the Amount Needed

• Estimate cloud volume:
  For large clouds, calculate the volume in cubic kilometers (km³).
  Example: If targeting a cloud area of 50 km² with a vertical height of 3 km, the volume is approximately 150 km³.

• Determine number of seeding points:
  Based on the cloud volume and seeding method, decide how many points or drops will be released.

• Apply dosage per volume:
  Assuming 0.1 grams per km³:
  [ \text{Total AgI} = \text{Cloud volume} \times \text{Dosage per km}^3 ]

[ \text{Total AgI} = 150 \text{ km}^3 \times 0.1 \text{ g/km}^3 = 15 \text{ grams} ]

For larger or more complex clouds, this amount can go up accordingly.

​

4. Environmental and Efficiency Considerations

• Always start with the minimal effective dose.

• Adjust based on real-time weather forecasts and cloud response.

• Use the latest meteorological data to refine the seeding plan.

​

5. Operational Precautions

• Maintain high purity Silver Iodide (~99%) to prevent contamination.

• Use precise dispersal equipment to ensure even distribution.

• Coordinate with local meteorological agencies and environmental regulations.
