Weather warfare

Weather warfare is a earth science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Weather warfare rather than just read about it. In short: Weather warfare is the use of weather modification techniques such as cloud seeding for military purposes. History Prior to the Environmental Modification Convention signed in Geneva in 1977, the United States used weather warfare in the Vietnam War.

Key takeaways

Weather warfare belongs to earth science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Weather warfare to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Weather warfare from memory before moving on to harder problems.

Reference excerpt

Weather warfare is the use of weather modification techniques such as cloud seeding for military purposes.

History Prior to the Environmental Modification Convention signed in Geneva in 1977, the United States used weather warfare in the Vietnam War. Operation Popeye saw the use of cloud seeding over the Ho Chi Minh trail. It was hoped that the increased rainfall would reduce the rate of infiltration down the trail. A research paper produced for the United States Air Force written in 1996 speculates about the future use of nanotechnology to produce "artificial weather", clouds of microscopic computer particles all communicating with each other to form an "intelligent fog" that could be used for various purposes. "Artificial weather technologies do not currently exist. But as they are developed, the importance of their potential applications rises rapidly." The Environmental Modification Convention (ENMOD), which was signed in Geneva on May 18, 1977, and entered into force on October 5, 1978, prohibits "widespread, long-lasting or severe effects as the means of destruction, damage or injury". In 1972 an ENMOD convention on weather warfare presented that this permits "local, non-permanent changes". The "Consultative Committee of Experts" established in Article VIII of the Convention stated in their "Understanding relating to Article II" that any use of environmental modification where this is done "as a means of destruction, damage or injury to another State Party, would be prohibited.". It also suggests all signatories are expected to abstain from using weather modification to cause harm at any scale, stating "military or any other hostile use of environmental modification techniques, would result, or could reasonably be expected to result, in widespread, long-lasting or severe destruction, damage or injury." However, the treaty does not directly condemn military use of weather modification when it does not directly cause harm, such as the United States' use of weather modification in the Battle of Khe Sanh in the Vietnam War. The limitations of the treaty, and its application only to signatory states, allow weather warfare to continue to play a role in warfare throughout the 21st century. The United States prohibits weather modification without permission of the United States Secretary of Commerce.

Worked examples

Example 1 — a first encounter with Weather warfare

Start with the simplest possible case. Write down what Weather warfare claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In earth science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Weather warfare before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Weather warfare ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Weather warfare

In research: Weather warfare appears in earth science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Weather warfare in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Weather warfare is common in secondary-school and first-year university syllabi. It links to neighbouring topics Meteorological hypotheses, Warfare by type, Weather modification, so understanding it makes those chapters shorter.
In everyday life: Look for Weather warfare outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.

Frequently asked questions

What is Weather warfare in simple terms?

Weather warfare is the use of weather modification techniques such as cloud seeding for military purposes. History Prior to the Environmental Modification Convention signed in Geneva in 1977, the United States used weather warfare in the Vietnam War.

Why does Weather warfare matter?

Because it connects several earth science ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study Weather warfare?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
