In PS238, the fact that the school is covered by Weather Satelites is frequently mentioned (and, at one point, weaponized), but even their control cannot stand up to the powers of The Rainmaker. (He's a lot more dangerous than he sounds.) The ghost of a nameless Native Shaman apparently also had weather-control powers when he was alive, and eventually gets to use them when he possesses a student with the ability to channel ghostly powers...

The Avengers (1998). Sir August De Wynter uses one to extort Great Britain. Slightly subverted in that he does plan to use it to make legitimate money (by "selling" weather to the countries of the world) but squeezes the Villain Ball tight by also threatening to bring natural disasters on the countries that don't comply.
De Wynter: Rain or shine...all is mine!
In the 1960s Bond spoof Our Man Flint, the Galaxy organization threatened to use its weather control device (which could also cause earthquakes) to bring the world to its knees unless the nations of Earth destroyed all of their nuclear weapons, aircraft and navies and accepted Galaxy's guidance.

At first he is only capable of causing basic weather events, such as rain, tornadoes and targeted lightning strikes, but later on he connects his invention to a decommissioned nuclear power plant, dramatically boosting its power and allowing him to create gigantic hail and ice storms. He is ultimately defeated when the heroes improvise their own version of the system by using satellites and missiles to create tornadoes that destroy his hideout.

Frank Herbert's Dune series, weather control is widespread, and is achieved with specialized satellites in orbit around a planet.
The female magic-users of the Sea Folk in Robert Jordan's The Wheel of Time primarily used their channeling to produce winds favorable for their boats. Their assistance in using a ter'angreal, the "Bowl of the Winds," to overcome a prolonged magical drought was a major plot point in the middle of the series. In this case, however, No Ontological Inertia was averted:
Caire: Do you think Weaving the Winds is like throwing the helm over on a darter? I just moved the rudder on a skimmer with a beam as broad as the world! He will take time to turn, time to know he is supposed to turn. That he must turn. But when he does, not the Father of Storms himself will be able to stand in his way.
In the Vampire Hunter D novels, weather control systems used to be ubiquitous in the now-extinct vampire civilization, used for practical purposes as well as entertainment, and were occasionally even weaponized. They, like everything else is breaking down After the End, resulting in some highly unpredictable or just plain unnatural weather patterns in large portions of the planet.
In Robert E. Howard's The Hour of the Dragon, Xaltotun tries to trap Conan the Barbarian by creating a flood with rains. He dismisses it as a fluke when it fails; actually, other magic was used against it.

In Orson Scott Card's Pastwatch: The Redemption of Christopher Columbus, the world of Twenty Minutes into the Future is recovering from wars and environmental disasters of the 20th and 21st centuries, and weather control satellites are the only means of keeping the remaining farmland fertile. Unfortunately, the increasing cloud cover means that they will stop being effective at some point, leading to worldwide starvation, contributing to the total collapse of human civilization. The loss of industry will also mean that humans will be unable to repair (or even reach) them.

Forgotten Realms got some impressive magic for this, too, up to Killing Storm spell that scoured a forest kingdom for 3 month so thoroughly it's still a near-desolate moor 10,000 years later. Netheril was covered in permanent 'Mavin's Worldweave' climate-shifting spells until most of it became subtropical, then water-drained by longterm 'Lifedrain' spells of Phaerimm — which explains why there's a hot desert so far up North that it borders a big glacier. In the middle of its North side lies the High Ice — over 30 millenia earlier, before continents' shapes changed, this area was swamped by the Sarrukh to drive out the Phaerimm. This kind of worked, but upset local ecological balance enough to do in their own empire too — which maybe gave Phaerimm ideas about drying spells and ecological warfare the next time. To the East stands the Great Glacier — a mountainous pile of ice grown around the tomb some power buried with his ice-related artifact; it used to cover Damara and Vaasa too, south of them was a forest of elves who they stopped its spread with magic; much later it shrunk for no obvious reason. Many of Elven mythals make local weather more pleasant and stable. As to the High Ice, returned Netherese melted a good portion, upsetting the climate over half of the continent... In short, for many millenia Faerûn didn't even have completely natural weather patterns.

Sonic & Knuckles, Mushroom Hill Zone Act 2, shows not just the weather changing, but the seasons as well. It goes from summer, to autumn (complete with leaves falling from trees), to winter, in less than 10 real-time minutes. Then, just before the boss fight, you destroy the machine that's causing it (a radar dish shooting lightning into the sky) and the level immediately reverts to summer weather.
Inverted in Star Fox Assault, where the machine keeps the frequent blizzards on Fichina in check, and needs to be repaired before the planet becomes completely uninhabitable again.
This is likely based on Titania in the original Star Fox, where the level starts in a blizzard, and halfway though you deactivate the weather control machine to clear the sky.
These show up all the time in various games in the Mega Man series, usually without any particular relevance to the plot, but just for fun effects on various levels.

A weather control machine is featured conservatively in the Tribunal expansion to The Elder Scrolls III: Morrowind under the city of Mournhold. Unlike some other Dwemer machinations, no attempt to justify it is given. Considering one of the valid settings includes "ash storm," whether or not it was built as a genuine weather machine is worth questioning. It never actually gets destroyed, despite being used by the Big Bad as part of a scheme to inspire fear and belief in her power — it is reset to inactive at the end of the main quest-line, but nothing keeps you from going down to it and setting it to the weather you want.
Ōkami features on of these in Kamui. It is used by demons to unleash a massive blizzard on the citizens of Wep'Keer.
Climatrol in Phantasy Star II. Meddling with it nearly floods the entire planet. Phantasy Star III also has a similar machine to control the tides and even the moons, but here it is somewhat justified as the world is actually a giant spaceship.

Though it's never explained how or why, it's implied that the activities of the Techno Union were screwing with the geothermal activity of planet Nelvaan and causing the winter weather that Obi-wan and Anakin observed. In any case, as soon as Anakin destroys the crystal core of their machine, the ice and snow immediately begins thawing.
Bucky OHare featured the Climate Converter, used by the Toads to turn Bucky's homeworld into a swamp.
Birdman episode "Versus Cumulus, the Storm King". Cumulus has machines that can create lightning storms, fog and clouds.
In My Little Pony: Friendship Is Magic, the weather of Ponyville is controlled by a weather factory managed by the pegasus ponies. In fact, the concept of uncontrolled weather is alien to the ponies, and one of their many reasons for fearing the Everfree Forest is the way that its weather could change on its own.
A low-tech approach was used in a Super Chicken episode, where a rash of elephants in the city leads Super Chicken and Fred to an Indian maharajah, who has shipped the elephants strategically for their weight to tip the earth's poles so he can enjoy snow.
Referenced in Transformers Prime. When natural disasters happen across the globe Agent Fowler sarcastically asks if the Decepticons have built a weather machine. Ratchet responds with "One that powerful, highly unlikely."
There is one major form of real-life weather control known as "cloud seeding", which doesn't involve a machine, but instead putting substances into clouds so the rain drops somewhere else. Results have been rather mixed, but the technique is still used fairly frequently.
Yes, the Yanks with Tanks tried it in The Vietnam War, in something called Operation Popeye in 1966-7. When revealed to the press, weather modification for military purposes was banned by Congress and then by an international agreement.
Except when it's done within U.S. borders, apparently, since cloud seeding is regularly performed over the various remote military installations in California and Nevada (Edwards AFB, White Sands, etc). It's considered more effective there because there aren't a whole lot of clouds over those unholy wastelands in the first place.
It works, but it's unclear whether it is to effective degree or not.
Cannon-like devices that blast powerful columns of air into oncoming thunderstorms have been used by farmers to try to disrupt the formation of hailstones, protecting delicate crops over a limited area. Evidence that they work is dubious at best, however.
Recently, its been reported that Abu Dhabi scientists have been able to use ionizers to create rain, thunder-, and hailstorms. The results aren't conclusive yet. The best that can be said is that it has rained more than usual after switching the ionizers on, during a dry season when it shouldn't be raining much at all.
The British science program me Bang Goes the Theory showed the actual manufacture of a cloud in a machine, and then the wind, lightning, rain and snow that came with it.
Various weather simulators exist, which can reproduce the effects of intense winds, downpours, wind-blown sand or dust, and even lightning on a small scale. Most are used to test materials and construction techniques to ensure they are weather-resistant, or to re-create harsh weather conditions to which cars or planes might be subjected.
