Advanced Weather

 --- *A physically-grounded weather overhaul for Minecraft: 28 weather types across all three dimensions, a real atmospheric simulation, and a full progression of craftable weather instruments.*    --- ## What is Advanced Weather? Vanilla Minecraft has three weather states: clear, rain, and thunder. Advanced Weather replaces that with a living atmosphere. Air pressure, temperature, dew point and wind are simulated continuously and drive **28 distinct weather types**, each with its own particles, fog, sky, sound and gameplay effects. Weather doesn't teleport between states: it *transitions* based on the current atmospheric conditions, and you can actually **read, predict and archive** it using an in-world progression of scientific instruments you build yourself. You can let it run procedurally, sync it to **real-world weather** at any location on Earth, or take full manual control. --- ## Features ### 🌍 A real atmospheric simulation Runs a continuous model: - **Air pressure** driven by layered simplex noise, with realistic velocity, damping and gusting. - **Temperature** derived from the weather type, the solar day/night cycle, adiabatic pressure effects and (optionally) the current season. - **Humidity** computed from temperature and dew point using the Magnus relative-humidity formula. - **Wind** with base intensity per weather type, pressure-gradient contribution and randomized gusts. - **Probabilistic transitions** - the next weather is chosen from a transition graph weighted by live atmospheric conditions, so a falling barometer genuinely means a storm is coming. - **Forecasting** - the engine projects the atmosphere forward in time to predict the *next* weather with a confidence score. - **Clouds** - a custom cloud renderer that reacts to the weather and the humidity/wind speed and direction. Everything is per-dimension and saved with the world. --- ### 🌦️ 28 weather types across three dimensions ## **Overworld (17):** #### Clear · Sunny · Cloudy · Overcast · Mist · Fog · Dense Fog · Drizzle · Light Rain · Heavy Rain · Freezing Rain · Thunderstorm · Snow · Blizzard · Hail · Windy · Sandstorm ## **Nether (6):** #### Nether Clear · Ash Storm · Brimstone Storm · Lava Rain · Netherstorm · Hellfire ## **The End (5):** #### End Clear · End Mist · Void Storm · Chorus Gale · Enderstorm A configurable HUD shows which weather type is active, along with the time of day (can be disabled in the config):  ### ✨ Atmospheric effects Each weather brings its own hand-tuned visuals and audio: - Volumetric **wind lines** and directional wind sound that scale with intensity and gusts. - Weather-specific particles: blizzard flakes, sand, ash, ground fog, freezing splashes, hail, ember/void particles. - **Rainbows** that can spawn after rain clears or during drizzle, **heat shimmer** in extreme heat, **water and lava ripples**, wind-blown **tumbleweeds** and drifting **chorus plants**. - Dynamic **fog, sky, cloud, sun, star and lightning** rendering that reacts to the current weather. ### ⚡ Weather that affects gameplay - **Hail** can damage crops, hurt exposed entities and break glass (each toggleable). - **Heavy rain** slows crop growth. - **Blizzards** deepen snow accumulation. - Mobs **seek shelter** from dangerous weather. - Lightning behaviour is reworked for storms. *(All gameplay impacts are individually configurable.)* ### 🔬 Instruments & progression Advanced Weather is also a **tech-progression mod**. You can't just read the weather, you have to build the tools. - **New ores & materials:** Cinnabar (→ washed dust → distilled into **Mercury**) and Bauxite (→ Alumina → carbothermic reduction → **Aluminum**, ingots, nuggets and sheets). A **Hammer** lets you crush and press by hand (or use Create's crushing wheels). - **Four core instruments**, each built from a calibrated heart: **Thermometer** (mercury vial), **Barometer** (spring), **Hygrometer** (sensitive fiber), **Anemometer** (cup rotor). - **Calibration Bench** and **Calibration Tool** - components must be calibrated before assembly, and sensors linked to stations. - **Portable** versions of every instrument for readings on the move. ### 📟 The weather station network Build a working meteorological station: - **Weather Station** - displays live readings; link sensors to unlock each measurement. Right-click with paper to **print a Weather Report**. - **Sensors** (Thermometer / Barometer / Hygrometer / Anemometer) with **realistic placement rules** - a thermometer must be sheltered from direct sky with airflow; an anemometer needs open sky and clear sides; etc. Bad placement gives bad readings. - **Weather Archive** - store reports and almanacs; it studies your measurement history to **forecast the next weather**, rejecting duplicates and reports older than its memory. - **Auto-Sampler** - automatically feeds station data into an archive at a configurable interval. - **Weather Detector** - emits redstone based on weather (rain, snow, storm, thunderstorm, hail, or an analog 0–15 wind signal). - **Weather Almanac** - a portable record of archived trends. ### 🌐 Real-world weather mode *(opt-in)* Enable it in the config and Advanced Weather will pull **live weather for any latitude/longitude on Earth** (via Open-Meteo) and reverse-geocode the place name (via OpenStreetMap Nominatim), mapping real conditions onto Minecraft's weather system. > **Privacy note:** this mode is **disabled by default**. When enabled, the coordinates you set in the config are sent to Open-Meteo and OpenStreetMap Nominatim to fetch weather and a location name. No data leaves your game unless you turn this on. --- ## Configuration Config files are generated in your `config/` folder (`advancedweather-common.json` and the client config). Highlights: - **Weather toggles** - enable/disable any weather type per dimension (Overworld, Nether, End). - **Gameplay** - `hailDamageCrops`, `hailDamageEntities`, `hailBreakGlass`, `heavyRainSlowCrops`. - **Instruments** - `stationRequiresSensors`, `sensorLinkMaxDistance`. - **Archive/forecasting** - record capacity, minimum records for a forecast, confidence curve, forecast horizon, data-aging thresholds. - **Real weather** - `realWeatherEnabled`, `latitude`, `longitude`, `syncIntervalMinutes`, `realWeatherOverridesCommands`. - **Create compat** - `enableCreateWindmillCompat`, `windmillWindThreshold`, `windmillDirectionAffectsOutput`, `windmillSpeedScaleFactor`. A **YACL config screen** is provided for in-game editing. --- ## Compatibility | Mod | Type | What it adds | |-------------------------------------|-------------------|----------------------------------------------------------------------------------| | **YetAnotherConfigLib (YACL)** | Required (client) | In-game config screen | | **Create** | Optional | Windmills react to real wind (speed & direction); weather data on Display Boards | | **Create: Aeronautics / Simulated** | Optional | Wind pushes simulated contraptions | | **Serene Seasons** | Optional | Season-aware weather types, temperature & dew point | | **JEI** | Optional (client) | Calibration Bench recipes in the recipe viewer | | **Iris Shaders** | Incompatible | Some shaders may be incompatible with the way that AW render its fog | --- ## Requirements - **Minecraft** 1.21.1 - **NeoForge** 21.1.230+ - **YetAnotherConfigLib** 3.6+ --- ## License Released under the **MIT License**.
