What are the factors affecting cloud seeding?
For summertime cloud seeding, only clouds that possess a sustained updraft of moist air, a lack of natural ice, and grow to heights cold enough to contain supercooled liquid water are suitable for cloud seeding. 3.
What chemicals are used in cloud seeding?
The most common chemicals used for cloud seeding include silver iodide, potassium iodide and dry ice (solid carbon dioxide, producing the green house gas). Liquid propane, which expands into a gas, has also been used. This can produce ice crystals at higher temperatures than silver iodide.
What are some advantages and disadvantages of cloud seeding?
Here we look at the various advantages and disadvantages of cloud seeding.
- Pros of Cloud Seeding. Rain Creation. Boosting of the Economy. Weather Regulation. Makes Dry Places More Livable.
- Cons of Cloud Seeding. Requires the use of Potentially Harmful Chemicals. It is Not Foolproof. It is expensive. Poses Weather Problems.
What are the advantages and disadvantages of cloud seeding?
Top 10 Cloud Seeding Pros & Cons – Summary List
| Cloud Seeding Pros | Cloud Seeding Cons |
|---|---|
| Cloud seeding can help to reduce poverty | Can lead to air pollution |
| Cloud seeding can be applied locally | Cloud seeding can contribute to acid rain |
| Especially helpful in dry regions | Soil pollution related to cloud seeding |
How long do sulfate aerosols stay in the stratosphere?
about 3-5 days
The sulfate aerosols absorb no sunlight but they reflect it, thereby reducing the amount of sunlight reaching the Earth’s surface. Sulfate aerosols are believed to survive in the atmosphere for about 3-5 days.
How does cloud seeding reduce air pollution?
Artificial rain works via a process called cloud seeding, during which chemicals are injected into the Earth’s atmosphere to mimic the composition of clouds. This then leads to precipitation in the form of rain or snow, thus cleansing the air and ridding it of excessive levels of contamination.
What are the positive effects of cloud seeding?
If cloud seeding is implemented, there will be increased harvesting and more food available from a wide variety of crops for the ever-growing human population. The process also has the potential to improve biomes, allow for more fertility and create more farming land and land that could be used to build better homes.
What is the benefit of cloud seeding?
The goal of cloud seeding is to prevent hail and other forms of damaging precipitation in some regions. When we transform ice into water to create more rain or snow, then we are increasing the risk of other adverse events. Flooding is a significant issue that can happen from this work.
