When it comes to the topic of modifying weather and controlling the climate, there are a lot of different views and worries about changing the weather and controlling the climate. Many people think that messing with the weather will harm the environment and that we are already seeing some of these effects, which could lead to climate change like global warming. Meanwhile, others believe that technologies like HAARP might cause earthquakes and have serious effects on our planet. In this article, we will look at the potential dangers of weather modification and we will discuss how ongoing weather modifications, like those from Mission Mausam, could be harmful.
While the concept of controlling rainfall and weather patterns may sound appealing, the reality is much more complex. Weather systems are incredibly intricate and interconnected, making it challenging to predict the full extent of the impact of human intervention. Past attempts at weather modification have shown limited success, with unintended consequences such as droughts or floods in other regions.
Attempting to alter natural weather patterns carries inherent risks. By tampering with the delicate balance of the atmosphere, there is a possibility of triggering unforeseen and potentially disastrous consequences. For example, altering rainfall in one area could lead to shifts in weather patterns elsewhere, affecting agricultural productivity and water resources in unintended ways.
India is taking a big risk to tackle its climate problems by trying to manage weather events like rain, lightning, and hail in the next five years. This project is called “Mission Mausam,” and it has the support of the government. As part of this mission, they are creating Mausam GPT, an AI model that will help improve how accurately we can predict the weather and might even allow us to change it.
The government is focusing on moving forward instead of dwelling on past failures. They want India to be one of the first countries to test weather modification on a big scale. However, this kind of technology hasn’t really gotten better and has actually caused problems for the environment.
India’s “Mission Mausam” is a project that wants to change how we manage weather by using technology to influence rain. In the next year and a half, the government plans to begin with experiments in labs to either increase or decrease rainfall. However, there are public concerns that such initiatives may contribute to global warming. The main aim, according to Earth Sciences Secretary M. Ravichandran, is to implement large-scale weather changes within five years. He mentioned that this project could even be used for special occasions like Independence Day, where they might consider stopping the rain.
In 2008, China employed its own weather modification program to influence weather forecasts for the Beijing Olympics, as reported by the BBC. The country conducted cloud seeding in the capital city to ensure that rainfall occurred before significant events such as the opening ceremony, rather than during them.
Is cloud seeding still being conducted in India?
Six years after Schaefer flew into a cloud lacing it with dry ice, India, post-Independence sowed the seeds in the field of rainmaking.
In 1952 late climatologist S. K. Banerji, the first Indian director-general of Indian Meteorological Department experimented with cloud seeding with salt and silver iodide through hydrogen-filled balloons released from the ground.
Tata firms also took stabs at cloud seeding in the Western Ghats region in 1951 using ground-based silver iodide generators. The Rain and Cloud Physics Research (RCPR) unit of the Indian Institute of Tropical Meteorology (IITM) in Pune carried out randomized warm cloud modification experiments through salt seeding during 1957-1966 in north India. Over the next three decades, India experimented in this direction in Maharashtra, Karnataka and Uttar Pradesh.
[https://www.tropmet.res.in/~caipeex/cloud-seeding.php ] [https://www.tropmet.res.in/~caipeex/Science_Plan_CAIPEEX_P1.pdf]Research on cloud seeding in India received a boost since 2018 with the Union Ministry of Earth Sciences investing in data collection and experiments.
Research by the IITM in Pune, especially over the last two years (2018 and 2019) will result in a white paper with the scientific facts on the ground for cloud seeding, should states wish to take it up as a measure to increase rainwater.
While the Union Ministry of Earth Sciences has no plans to have a national programme on cloud seeding, it has already spent Rs 45 crore on research in 2018. In 2019, the work will continue, costing a total Rs 100 crore.
The IITM has initiated a national-level campaign designed to make progress in aerosol and cloud microphysics observations over the Indian region, which can be used to propose guidelines for cloud seeding. The project called the Cloud-Aerosol Interaction and Precipitation Enhancement Experiment (CAIPEEX), will be focussing on aerosol-cloud-precipitation interactions in the pre-monsoon and monsoon environment
Beset by drought and water crisis following deficient rainfall Maharashtra and Karnataka are gearing up for cloud seeding this year. The country received 17 percent less rain than average since the advent of the monsoon on June 1.
Nashik: Make In India Rocket For Farmers For Cloud Seeding
Using cloud seeding methods together with AI-powered weather forecasting tools like “Mausam GPT,” the goal is to enhance India’s capability to handle severe weather situations. An important part of this strategy is to create a strong network of advanced radars, supercomputers, satellites equipped with high-tech sensors, and GIS-based decision support systems.
On 11 September 2024, the Union Cabinet approved the ₹2,000 crore Mission Mausam over two years, which focuses on significantly upgrading the equipment used by key organizations like the India Meteorological Department, the National Centre for Medium-Range Weather Forecasting, and the Indian Institute of Tropical Meteorology. These organizations form the backbone of India’s weather and climate forecasting capabilities across various time scales.
What is Mission Mausam?
This is slightly different from the National Monsoon Mission, launched in 2012 developed state-of-the-art weather and climate prediction models through intensive computing.
- Nodal Ministry: Mission Mausam is to be chiefly implemented by the Ministry of Earth Sciences (MoES).
- Aim: Mission Mausam’s objective is to enhance India’s ability to predict and respond to extreme weather events and the impacts of climate change.
- Its focus will be on improving observations and understanding to deliver highly accurate and timely weather and climate information across temporal and spatial scales.
- Instruments: MoES will install 60 weather radars, 15 wind profilers and 15 radiosondes.
- Weather Radars: It is like a dish-antenna that transmit radio waves and would detect rainfalls, snowstorms and other weather phenomena..
- Wind Profilers: It is a special radar that measures wind speed at different heights. It helps in better prediction. It is used by pilots as well.
- Radiosondes: It is a small device attached to a balloon. It is used to measure temperature, pressure, and humidity.
- Cloud-Simulation Chamber: It will be set up in IITM where scientists would work on artificial clouds.
- Cloud-seeding: Cloud seeding is a kind of a weather modification technology to create artificial rainfall. It works only when there are enough pre-existing clouds in the atmosphere.
| Maharashtra and Cloud-Seeding: Based on IMD forecast in April 2015, the Government of Maharashtra took a note of deficit rainfall forecast and planned cloud seeding experiment. |

- Control Lighting: There are also plans to control lightning.
- In India, lightning strikes are the number one cause of nature-propelled deaths, above floods and landslides. Due to this the scientists are hoping to tweak the electrical characteristics of the cloud so that there are fewer lightning strikes.
- Benefits: This will help in detecting accurate weather conditions which will further help during eviction during disasters.
- This will also give a boost to solar and wind energy due to better detection thus improving daily lives.
- Challenges and Ethical Concerns: Weather is a natural phenomenon which cannot always be predicted 100 percent.
- Long-Term Impact: The mission aims for cloud-seeding which is weather modification or changing the characteristics of clouds.
- This could have negative aspects as well. One place might have heavy rainfall and other places would have low rainfall. This would further deepen the conflict between states over water-sharing.
- Ethical Concerns: At the same time it raises ethical concerns because at the end of the day humans are interfering with how nature works.
- Long-Term Impact: The mission aims for cloud-seeding which is weather modification or changing the characteristics of clouds.
DECADES OF QUESTIONS
For almost a hundred years, people have been trying to control the weather.
One of the first to experiment with this was Vincent Schaefer, a scientist at General Electric, who started cloud seeding in the 1940s. During and after World War II, Schaefer focused on stopping ice from forming on airplanes while they were flying. To do this, he created a unique homemade freezer to learn more about how ice develops in clouds.
One day, Schaefer walked into the lab and found out that his freezer was off. He wanted to fix it fast, so he put a block of dry ice inside. Right away, a beautiful cloud of sparkling ice crystals appeared in the air.
In 1946, Schaefer carried out the very first real cloud seeding experiment using an airplane. He released 6 pounds of crushed dry ice into a cloud over the Adirondack Mountains in New York. Almost right away, it started to snow.
In future experiments, Schaefer and his team at GE found out that some particles are better at making ice crystals form. They discovered that silver iodide is one of the most effective ones.
The U.S. government became really interested in weather modification pretty fast. In the following years, they spent money on cloud seeding experiments for various reasons, including dealing with droughts and even for military uses.
One significant event happened in 1947 when Project Cirrus, a joint effort between General Electric and the U.S. military, tried to change a hurricane for the first time. On October 13, they dropped almost 200 pounds of dry ice into a cyclone that was swirling near Florida’s coast.
In the 1960s and early 1970s, the federal government kept trying out cloud seeding to control hurricanes, but it didn’t really work. Scientists figured out that it wasn’t a good method.
Starting in the early 1960s, the Bureau of Reclamation supported a bunch of cloud seeding tests called Project Skywater, which was meant to increase water supplies in the Western states. The results from this project were not very consistent.
In the late 1960s and early 1970s, the U.S. military conducted experiments on weather modification as a potential warfare tactic. Known as Operation Popeye, this initiative sought to create sufficient rainfall to hinder enemy supply lines in Vietnam.
However, these attempts didn’t last long. An international treaty established in 1977 prohibited the military use of weather modification.
A recurring theme in many of these initial experiments was their lack of effectiveness; they were either deemed impractical, swiftly abandoned, or scientists were unable to assess their success.
A lot of research happened in the 1960s, 70s, and 80s, according to French, a scientist from the University of Wyoming. He mentioned that everything kind of stopped when people realized that agencies were spending huge amounts of money every year, but the results were still unclear.
He explained that studying weather modification is really tough to plan and execute.
To show that cloud seeding actually makes a difference, scientists need to prove that the results wouldn’t have happened without it. This means they have to set up an experiment with at least two tests—one where they use cloud seeding and one where they don’t—both in the same place and under the same weather conditions.
The weather can change really fast, which makes it hard to study. Even when it is possible, scientists need fancy tools like high-tech radar to keep track of everything. This kind of technology hasn’t been around for very long.
Because of this, most cloud seeding research has depended on statistical studies. These studies look at how much rain is created by cloud seeding in one place and then compare it to another place where cloud seeding didn’t happen.
The two environments in these studies are not the same. This means they can’t clearly show that the rain created by cloud seeding in one place wouldn’t have occurred without it.
In 2003, the National Research Council released a detailed report about changing the weather, pointing out these issues. They stated that “there is still no strong scientific evidence that intentional weather modification works.”
Cloud Seeding: What You Need to Know
India has a history of engaging in weather modification initiatives.
Common chemicals used for cloud seeding include silver iodide and dry ice (solid carbon dioxide), Liquid propane (which expands into a gas). The use of table salt is becoming more popular.
In India, cloud seeding operations were conducted during the years 1983, 1984–87,1993-94 by Tamil Nadu Govt. due to severe drought. Karnataka Government Launched Clouding Seeding Project Varshadhari 2017. Cloud seeding operations were also conducted through U.S.-based Weather Modification Inc. in the state of Maharashtra. In 2008, there were plans for 12 districts of the state of Andhra Pradesh.
One C-band doppler weather radar will be installed at Bengaluru this year, Jitendra Singh, Minister of State (Independent Charge), Science and Technology, has said.
[ https://www.thehindu.com/news/cities/bangalore/bengaluru-will-get-doppler-weather-radar-says-jitendra-singh/article68432688.ece ]The government has implemented pilot projects like the Cloud Aerosol Interaction and Precipitation Enhancement Experiment (CAIPEEX) in Maharashtra, aimed at examining cloud characteristics and increasing rainfall.
Challenges
- Potential Side-effects: The chemicals used in cloud seeding might be potentially harmful to plants, animals, and people, or the environment.
- Abnormal Weather Patterns: it might ultimately change climatic patterns on the planet. Places that normally receive moisture might start experiencing drought due to the artificial process of adding chemicals to the atmosphere to stimulate rain.
- Costly: It involves processes such as delivering chemicals to the sky and releasing them into the air by flare shots or airplanes, which involves huge costs and logistic preparation.
- Pollution: As the artificial rain falls, seeding agents like silver iodide, dry ice or salt will also fall. Residual silver discovered in places near cloud-seeding projects are considered toxic. As for dry ice, it can also be a source of greenhouse gas that contributes to global warming, as it is basically carbon dioxide.
Increased aircraft activity in residential areas of Bangalore has led many residents to speculate that cloud seeding operations are being conducted from HAL (Hindustan Aeronautics Limited) airport. Over the last four years, a lot of residents have noticed big changes in the weather, which makes them curious about whether cloud seeding is affecting it. People are also worried about the noise and air pollution caused by the training flights from HAL. The government has not sought public input on cloud seeding initiatives, which could have long-term implications for air quality. As a result, residents are experiencing health issues, particularly respiratory problems. Historically, cloud seeding has not proven effective, and there are doubts about its success in the future, especially as government actions appear to disrupt natural processes and contribute to air pollution.
Methods and Techniques
Types of Cloud Seeding: Cloud seeding encompasses various techniques designed to alter weather patterns and enhance precipitation. Common methods include:
- Cold cloud seeding: Introducing seeding agents such as silver iodide or potassium iodide into cold clouds to stimulate the formation of ice crystals and enhance snowfall.
- Warm cloud seeding: Seeding warm clouds with hygroscopic materials like salt particles to encourage the growth of water droplets and trigger rainfall.
- Dynamic cloud seeding: Modifying cloud dynamics through aircraft-generated turbulence or shock waves to enhance precipitation efficiency.
Delivery Mechanisms: Cloud seeding operations rely on specialized delivery mechanisms to disperse seeding agents into target clouds effectively. These mechanisms include:
- Aircraft seeding: Fixed-wing aircraft or drones equipped with dispensing systems for releasing seeding agents into clouds at specific altitudes and locations.
- Ground-based generators: Stationary devices that emit seeding agents into the atmosphere, often positioned in strategic locations to target passing clouds.
- Remote sensing and control systems: Advanced technologies for monitoring cloud parameters, analyzing weather data, and remotely triggering seeding operations based on predetermined criteria.
Targeting Clouds: Effective cloud seeding requires careful selection and targeting of suitable cloud systems. Meteorologists use a combination of satellite imagery, radar data, and atmospheric modeling to identify clouds with optimal characteristics for seeding. Factors such as cloud type, altitude, temperature, and moisture content are taken into account when determining seeding targets.
Weather manipulation is important, but is it really safe?
In India, the rise in extreme weather events such as catastrophic floods, severe droughts, and intense hailstorms has been linked to weather modification efforts. The Mission Mausam initiative could provide India with a strategic advantage in addressing these challenges. For instance, the ability to inhibit rainfall to avert flooding or to generate artificial rain during dry spells could be transformative. India is spending Rs 2,000 crore over two years on this mission, showing how serious they are about it, and it’s likely to grow as more research is done. Should they go ahead with it?
Weather modification, like cloud seeding, is a topic that sparks a lot of debate. Around the world, cloud seeding hasn’t always worked well. Countries such as the US, Russia, and China have tried these techniques but often see mixed results. Even Madhavan Rajeevan, a former Secretary of the Ministry of Earth Sciences, mentioned that “the technology is complex” and still needs more development. Many people believe that it could actually harm nature even more, especially considering the issues we already have from chemical weather modification.
Now, let’s explore the world of cloud seeding and unravel the mysteries and secrets behind this innovative weather modification technique.
