Tornado7
Tornado7 takes vanilla weather out of the game and puts a living atmosphere in its place. Clouds form because the air makes them. On a hot humid afternoon the sky builds into supercells, and if the wind turns with height, one of them drops a tornado. Hurricanes wind up with a calm eye in the middle that you can fly into. And if you keep climbing, the sky goes black and the whole solar system is waiting up there.
It started as a storm chasing mod and it kind of got out of hand. These days it has eleven chase vehicles, a radar truck, a hurricane hunter plane, a rocket and three spaceship engines. Everything can be crafted in survival.
Watch the 6.3 trailer:
The sky
None of this is particles stuck onto rain. Every storm is a real volume of cloud, lit by the sun, with a shape that comes from how it works.
- Supercells have a flat dark base, a rotating updraft you can see turning, an anvil blown downwind, a wall cloud and an inflow band. You can tell what a storm is doing by looking at it, the same way real chasers do.
- Tornadoes come in over twenty shapes, from thin ropes to cones, cylinders, hourglasses, huge wedges and multi-vortex monsters, EF0 to EF5 (and an EF6 if you want to see the world end). Weak ones touch down leaning. Violent ones stand straight. They rope out at the end or get choked by their own storm's downdraft.
- Hurricanes go from tropical storm to category 5, with rain bands, an eyewall and a quiet eye with blue sky above it.
- All ten cloud types show up on their own schedule, so a warm front really does warn you hours ahead: cirrus first, then a halo around the sun, then grey altostratus, then rain.
- Hail that bounces and melts, lightning, rain thick enough to lose a truck in, morning fog, dust devils, wildfires and fire tornadoes.
How serious it gets is up to you
Pick a mode in the config:
- Arcade. Any big storm can drop a tornado. Pure chaos.
- Simplified. One atmosphere for the whole world, and every day has its own mood.
- Excessive Realism. Every region has its own temperature, dew point, wind and stability. Mornings sit under a cap and nothing happens. Sometime in the afternoon the cap breaks and everything fires at once. Straight wind shear gives you squall lines, curved shear gives you rotating supercells, and a storm that rained itself out leaves cold air behind, so the same spot won't keep producing all day.
Type /t7m weather and you get the sounding for the spot you're standing on: CAPE, CIN, the cap, shear, helicity and the storm mode. Read it right and you know where to go.
Chasing
Eleven vehicles are ready to go: TIV1, TIV2, Titus, Titan, Dominator 1, 2 and 3, Scout, Tornado Wrangler, Tornado Attack and the DOW6 mobile radar truck. They drive like real trucks. They have weight, grip and body roll, they slide if you brake into a corner too hard, and the heavy ones feel heavy. Drop the spikes and hydraulics, sit tight, and let the tornado go over you. If your truck's wind rating is high enough.
You can also build your own. Any structure with a seat and four or more wheels becomes a car, and its weight, armor, spikes and hydraulics are measured from what you actually built.
The gear:
- Laptop with four radar views: reflectivity, velocity, correlation coefficient and the close range feed from your DOW6.
- DOW6 radar truck. Park it, raise the dish, and it sees the inside of the tornado in detail no distant radar can.
- Weather balloons and dropsondes that send back a real sounding, plus a thermometer and a hygrometer.
- Probes like TOTO and the VORTEX2 pods that you drop in the tornado's path.
- FPV drone, a weather radio that reads out watches and warnings, and a repair station for the truck you just wrecked.
- The Atmosphere Sandbox. Put a tiny atmosphere inside a box, turn the knobs, and watch it go from clear sky to a supercell on a fast clock. Warm and cold front blocks let you force a squall line or a funnel whenever you want.
The hurricane hunter
New in 6.3: a WC-130J weather plane. Its flight model was checked against a published study of the real aircraft, so it climbs, turns and stalls the way the real one does. Walk around the cargo bay while it flies, flip switches in the cockpit, put it on autopilot and drop sondes into a storm. Fly through a supercell and you'll come back with hail dents and maybe a lightning strike. Fly into a hurricane and the whole plane shakes until you punch through the eyewall into the calm eye.
Space
Climb high enough and the air runs out. Up there is a real solar system: the Sun and all eight planets on proper orbits, moons included. Flying works a lot like Kerbal Space Program, with a navball, SAS, a tablet with a 3D map and an autopilot for transfers.
You can land on the Moon, Mars, Mercury, Venus, Europa and Titan. Europa has an ocean under the ice and geysers that break through it, Titan has its own ocean life, and the gas giants are clouds all the way down. There's even a black hole and a pulsar you can spawn with a command.
Getting there:
- The RSP rocket. A multistage launcher with boosters, a fairing, a capsule and a satellite on top. The stages really separate, onboard cameras follow the flight, satellites stay in orbit and the capsule comes home on parachutes.
- Your own ship. Build one with Create Aeronautics and bolt one of three engines to it. Orion rides a chain of small nuclear blasts, Daedalus is a fusion torch, and the warp drive bends space to jump between planets.
- Spacewalks. Step outside, grab the hull and pull yourself along it.
Not sure where to start?
A small cloud buddy shows up and teaches you everything in 42 short voiced lessons, in English and Russian: driving, the radar, reading the sky, flying the plane, getting to orbit.
Performance
The clouds test your GPU on first launch and pick a preset that fits. Integrated graphics and older cards get a lighter one automatically, and if the shaders can't compile at all, the mod quietly falls back to a simple renderer instead of crashing. There are five sharpness levels, plus adaptive quality that drops detail for a moment when your FPS dips. It runs on laptops and old PCs, not just on gaming rigs.
Works with
None of these are required.
- Create Aeronautics and Sable. Tornadoes push, spin and tear apart physical builds. Wood comes apart, steel and stone mostly just shake. The spaceship engines need these two.
- Vivecraft. Full VR. Fly the plane with your hands, hold the steering wheel, steer ships with the stick, even ski.

All Versions
+ Add Version
Ball lightning: spawns under storms/near lightning strikes; rolls on rails; attracted to metal; sparks (stronger vs iron armor); can ignite, sometimes explodes and breaks glass. Settings: Ball Lightning, Ball Lightning Rate, Ball Lightning Blasts.
Storms Come To You (off by default): supercells/tornadoes head toward player; tornado passes nearby at least once. Pass Distance = side offset.
SHARPpy-style soundings: diagram, hodograph, CAPE, CIN, SRH, STP, SCP, other indices, hazard type. TORNADO7 MODEL panel shows actual in-game result for that air. Forecast up to +12 h.
Weather balloon rises 20–26 km, drifts with wind. Open data: Shift + RMB with balloon, laptop Soundings app, or /t7m sounding [forecast].
# **Fixed**
Vehicles no longer damaged just by driving downhill. Fall damage unchanged, now also applies to homemade vehicles.
Fixed “beyond world border” death in space/on planets on servers with world border.
/t7m aimtoplayer: supercell no longer detaches from tornado or disappears.
Clear-sky lightning (previously came from small cumulus).
Infinite loading on weak PCs: after 30 s press Space to play; after 4 min game starts itself.
Transformer flash rendered in wrong place.
# **Faster**
Stormy sky: expensive cloud renderer only where storm can be on screen. Storms without squalls/funnels use lightweight renderer; rain under storm cheaper.
Adaptive quality maintains target FPS (default 60, Adaptive Target). First enables mode where clouds are calculated for only 1/8 of pixels per frame.
Laptop 10–30x lighter (radar, Soundings, desktop); sounding screen 2x lighter. Tablet, aircraft UI, assistant hints also cheaper
- Tornado7 6.3**
This is the biggest update the mod has ever had. 6.2 was a storm chasing mod. 6.3 is a storm chasing mod with a hurricane hunter plane, a rocket and a solar system above the clouds. Here is everything that changed since 6.2.2, the first NeoForge 1.21.1 release.

## New
### The WC-130J hurricane hunter
- A flyable WC-130J weather plane with a flight model checked against a published study of the real aircraft.
- Walk around the cargo bay in flight, use the clickable cockpit, flip switches, run the autopilot.
- Drop sondes into storms and get a real sounding back.
- Hail dents, lightning strikes, a shaking airframe inside a hurricane, voice warnings, and a crash if you push it too far.
/t7m planeand/t7m plane runwayto get flying quickly.
### Hurricanes
- Tropical cyclones from tropical storm up to category 5, with rain bands, an eyewall and a calm eye you can fly into.
/t7m cyclone <wind>,/t7m cyclone cat <0-5>,/t7m cyclone info,/t7m cyclone clear.
### Space
- Climb high enough and you leave the atmosphere. Up there is the Sun and all eight planets on real orbits.
- Land on the Moon, Mars, Mercury, Venus, Europa and Titan. Europa has a hidden ocean and geysers, Titan has ocean life, the gas giants are clouds all the way down.
- Flying works like in Kerbal Space Program: navball, SAS, a space tablet with a 3D map, and an autopilot for transfers.
- A black hole and a pulsar you can spawn with
/t7m spawn black_holeand/t7m spawn pulsar. - Spacewalks: step out, grab the hull and pull yourself along it.
### The RSP rocket
- A multistage launcher with real stage separation, onboard cameras, satellites that stay in orbit and a capsule that lands on parachutes.
- Every part has its own crafting recipe.
### Spaceship engines
- Three engines for ships built with Create Aeronautics: Orion (a chain of small nuclear blasts), Daedalus (a fusion torch) and the warp drive (jumps between planets).
- Seats work on the way between worlds, and SAS figures out which way your ship's nose points from where the thrust goes.
### Two new interceptors
- Titan** and **Dominator 2**. That makes eleven vehicles in total, counting the DOW6.
### Skis
- Skis, boots, helmet and poles. Push off with the poles, carve down mountains, and wipe out in style.
- Works in VR too.
### The cloud buddy
- A little cloud that teaches you the whole mod in 42 short voiced lessons, in English and Russian.
### A real atmosphere in Excessive Realism
- Every region gets a proper sounding: CAPE, CIN, the level of free convection, and a cap. Mornings sit under the lid doing nothing, the cap breaks in the afternoon and everything fires at once. Mountains and sea breeze fronts break it early, so storms start on boundaries first.
- Wind at two levels gives a hodograph, and helicity decides the storm mode: pulse storm, multicell, squall line or supercell. Straight shear means damaging wind, curved shear means tornadoes.
- Storms use up the air they grew from. A cell that just produced leaves a cold pool behind and goes quiet for hours, so severe weather comes in waves.
- Moisture comes from somewhere now: the wind carries it off oceans, jungles and swamps, and deserts dry it out.
/t7m weatherprints the whole sounding for where you stand.
### Wildfires
- Wildfires that spread and burn out on their own, and fire tornadoes that really burn.
/t7m fire <intensity> <radius>,/t7m spawn firetornado <radius> <windspeed>.
### And more
- A DOW view on the laptop: switch to it and the scope shows your DOW6 truck's own close range beam, with the inside of the tornado in real detail.
- The Atmosphere Sandbox zooms properly now. Storms keep their shape at any scale instead of stretching into needles.
- Hydraulics on your own builds now lower the hull onto the ground, so the wind can't get under it.
- A new loading screen.
- The laptop works like a real computer now, and the radar was rewritten from scratch.
- Tornadoes now push, spin and break physical builds from Create Aeronautics and Sable. Wood comes apart, steel mostly shakes.
- Vivecraft: fly the plane with your hands, hold the steering wheel, steer ships with the stick.
- Every item in the mod can be crafted in survival.
## Reworked
- The supercell** was rebuilt from the ground up as one storm instead of separate pieces: a rotating mesocyclone, a proper wall cloud, an anvil that spreads with the wind.
- The tornado funnel** was rebuilt, and tornadoes now follow their storm instead of wandering off on their own.
- The whole cloud sky** runs on a new engine. Clouds form by region and for a reason, and storms fire where the air can actually support them.
- All ten cloud types** were redone, including cirrus with sun halos and patchy cirrocumulus.
- Ordinary thunderstorms and gust fronts** now exist next to supercells, and storms go through a real life cycle.
- Lightning and night** look completely different: real bolts, and nights that are actually dark.
- Driving:** wind now acts on the whole body of a vehicle, trucks can roll over, dents land where you got hit, and mud, sparks and tyre marks react to the ground. Handling of every interceptor was retuned on a test track.
- Dust devils** got their own look.
## Performance
- Much faster storms and clouds. Weak PCs and integrated graphics went from single digit FPS to playable.
- The mod tests your GPU on first launch and picks a fitting preset. If shaders can't compile, it switches to a simple renderer instead of crashing.
- Adaptive quality drops detail for a moment when FPS dips.
- Shaders no longer take forever to compile on first launch.
## Fixed
- Freezes when arriving at planets.
- Clouds sometimes moving way too fast.
- Storms, hurricanes and tornadoes being cut off at a distance.
- Things disappearing under a supercell or inside a hurricane.
- Rain not reaching the ground, and rain falling inside the plane.
- Tornadoes in mountains.
- The mouse being stuck after leaving some screens.
- Ships freezing in space far from the world center.
- Many smaller things.
Mod Features and Keybinds
- =** — Open the weather map (to find out a tornado's strength, you need to place an interceptor or a probe in its path).
- E** — Aim your cursor at the vehicle to get in.
- Q** — Deploy (anchor) the vehicle so you don't get blown away by the tornado!
- R** — Scan the tornado with a probe to get the wind speed and EF category (only works if the vehicle is deployed).
- Space** — Get out of the vehicle!
Main Mod Commands
The core command for the mod is /t7m:
- /t7m spawn tornado <ef0-ef6> [shape]** — Command to spawn a tornado.
- /t7m spawn supercell** — Creates a supercell that can spawn a random tornado!
- /t7m stop all** — Instantly deletes all tornadoes.
- /t7m stop nearest** — Deletes tornadoes within a 2000-block radius.
