Dynamic Weather

Dynamic Weather

**Realistic storms, supercells, tornadoes and hurricanes for Minecraft.**
Volumetric clouds drift across the sky, thunderstorms build up on the horizon and roll over the land - and sometimes they bring a tornado with them.

> ⚠️ **Alpha version** - bugs are expected! Please report them so they can be fixed.

> ⚠️ **Photosensitivity warning:** this mod contains flashing lights such as lightning. Flashes can be reduced with the reduceFlashing option in the config.

🌪️ Tornadoes

• **Realistic formation:** a rotating wall cloud lowers, a funnel slowly reaches down and touches the ground
• **EF0 to EF5** - the rating is based on the wind speed (Enhanced Fujita scale)
• **Different shapes:** rope, cone, stovepipe, wedge, drillbit and multi-vortex
• The funnel has the color of the storm cloud and widens where it meets the cloud
• Visible from **any distance**, even through rain
• Tornadoes **travel with their parent supercell** and finally rope out and dissipate
• **Block destruction:** every block has its own wind resistance - glass breaks first, wood before stone. Strong tornadoes tear blocks out up to 30 blocks away and throw debris through the air
• Players, mobs and items get **pulled in and lifted up** - but you are safe inside a closed building
• Inside a tornado the air is full of **swirling dust**, and near strong tornadoes you can't see anything but dust and lightning - even through your windows

🌀 Hurricanes, typhoons & squall lines

• **Hurricanes and typhoons** form over the ocean: a calm eye, an eyewall with extreme winds and spiral rain bands. The wind circles around the eye
• **Squall lines:** long, fast-moving lines of thunderstorms with destructive gusts and constant lightning

⛈️ Weather

• **Volumetric clouds** with sunlight, shadows and smooth movement
• **Supercells** with a rotating mesocyclone, cauliflower-like towers and an anvil
• Many weather types: **drizzle, rain, showers, downpours, thunderstorms, cumulonimbus clouds, supercells, hailstorms, downbursts, squall lines, hurricanes, typhoons, sleet, blizzards and dust storms**
• Weather depends on the **biome**
• Clouds and storms all move with the same **wind direction**
• **Grass and trees bend in the wind** - the stronger the wind, the more they bend
• **Wind-driven rain**, hail that can hurt you and break glass, **ultra lightning** salvos
• Inside a storm the **atmosphere changes** - dark fog and very low visibility
• **Indoors** you hear the wind whistle, windows rattle and the roar of an approaching tornado

🏠 Storm-proof building

• **Windows** in 12 materials (plain, grid, barred, with shutters) that open, close and connect into tall windows when stacked
• **Glass doors, reinforced doors** and an indestructible **storm cellar door**
• Open doors and windows **swing and slam in the wind**
• **Barricade boards:** board up windows and doors so they can't be opened or blown open

📡 Storm chaser equipment

• **Weather Radar** and **Handheld Weather Radar**
• **Tornado Siren** that sounds automatically when a tornado is nearby
• **Anemometer** (wind speed) and **Barometer** (air pressure and forecast)
• **Severe weather warnings** in chat
• The **Wandering Trader** sells storm equipment
• Everything can be found in its own **Dynamic Weather** creative tab

ℹ️ Notes

• Required on **both client and server**
• Volumetric clouds can be demanding on weaker PCs - lower the cloud quality in the config if needed
• Not tested with shader packs or rendering mods like Sodium/Embeddium yet
