Project Atmosphere

Changed

• Reworked wind handling across the mod to remove inconsistencies and ensure all systems use the same wind source and direction convention.
• Wind particles now sample wind every tick at their own position and smoothly steer toward it, producing real bending instead of straight trajectories.
• Player wind influence now uses Weather2-style steering applied after input, with a noticeable effect only above 11.1 m/s.
• Non-player living entities use a separate steering path with optional gust blending and higher drift caps.
• Wind direction vectors are now consistent across particles, entity forces, and SimpleClouds cloud drift.
• Cloud regions now apply a stable per-cloud direction bias plus slow wobble and slight speed variance to reduce apparent stacking.
• Temperature clamping now logs a debug warning with context and stack trace to track runaway sources.
• Server commands are now registered under the /pa root (for example /pa temperature and /pa spawnTornado).
• Wind-driven neighbor mixing now clamps its factors and deltas to stop runaway temperature spikes from spreading.
• Added weather snapshot and world-effects hooks, including rain-driven fire/campfire extinguish, cauldron filling, and dense-cloud sunburn suppression.
• Region fallback generation now ensures biome keys are present and regenerates any regions that contain only min/max clamp values.
• Wind steering now ramps near the threshold so low winds no longer slow the player.
• World effects skip sampling when no rain is present and no custom effects are registered, reducing tick load.
• Wind drift now applies as a directional add without reducing existing player speed.
• Player wind now uses intermittent gust impulses (no conveyor steering), with configurable thresholds and caps.
• Wind particle steering now caches region wind samples per tick to reduce client overhead.
• Client cloud culling now uses a single pass per tick to avoid quadratic scans.
• Creative/spectator players are immune to wind gusts, and gust impulses no longer reduce current player speed.
• Sprinting players now ignore gusts unless winds reach extreme thresholds.
• Surface wind now comes from the low-wind layer and no longer treats gust headroom as baseline speed.
• Reduced default wind push scales and player gust caps by ~3x for gentler movement impact.
• Thermometer now syncs the client day-forecast temperature so it no longer shows the 0.5 fallback.
• Instrument readouts now use server-side values in multiplayer instead of showing default client fallbacks.
• Storm sirens now play the severe-storm sound only once per continuous storm event.

Fixed

• Fixed a wind particle crash.
• Fixed wind speed being far too low due to a unit mismatch in the wind equation (hPa vs Pa), which was suppressing the computed wind magnitude.
• Fixed a 90° wind direction offset caused by inconsistent sin/cos mapping between systems.
• Fixed wind fallback behavior and cleaned up wind selection usage to reduce edge-case inconsistencies.
• Wind forces now respect exposure, skipping entities in water or lava, under cover, or colliding horizontally.

Notes

• Storms have been observed spawning again in testing (cumulus clouds and a wall cloud), so storm generation appears to be working correctly.
• Please report any unusual wind behavior, particle issues, or storm spawning problems so I can continue monitoring and tuning.

Project Atmosphere 0.8.0.0

Project Atmosphere 0.8.0.0 continues the large internal refactor of the forecast and runtime systems, focusing on simulation stability, improved diagnostics, and better atmosphere state correctness.

This update stabilizes the new region-first runtime architecture while introducing deeper telemetry tools and improved safeguards for live atmospheric evolution.

Note:
This update is temporarily incompatible with PA x TFC.
A compatibility update is already planned and will restore support soon.

---

Changes

Forecast and Runtime

• Continued the transition to a region-first forecast runtime architecture.
• Reduced reliance on legacy biome-key runtime systems.
• Forecast baselines have been stabilized as part of the ongoing refactor.

Atmosphere Simulation

• Added humidity budget instrumentation, including ocean and wind integration.
• Completed the cloud-water coupling system for humidity simulation.
• Added pressure restore toward forecast targets with soft deviation guards and anomaly reporting.
• Added temperature restore toward forecast targets with soft deviation guards and anomaly reporting.
• Reworked cyclone and cloud ownership logic so cyclone-driven storm visuals are no longer immediately overwritten by cloud sampling.

Telemetry and Debugging

• Added new telemetry exports for atmosphere coupling, including target vs live values for:
  • Temperature
  • Pressure
  • Humidity
• Added humidity budget diagnostics and improved tracking of cloud-water interactions.
• Added anomaly markers to help diagnose pressure and temperature drift during runtime.

Compatibility

• Dynamic Trees compatibility remains optional, allowing the mod to load normally even if Dynamic Trees is not installed.(This module is a work in progress you should always disable it)

Fixes

• Fixed a telemetry export crash on JDK 17 caused by Gson reflective access to java.time.Instant.
  Explicit serialization for Instant is now used.

---

Notes

• This release contains no client or HUD changes.
• Build verified successfully on JDK 17.

---

Ongoing Work

• Forecast generation is now in a stable state.
• Current tuning work focuses on live runtime evolution, particularly temperature and humidity oscillations observed in some active regions.

Project Atmosphere

Added

• TFC canyons, TFC salt marshes biomes support.
• Crafting recipes for dust and sand layers.
• Wind bending for realistic particles (smoke, ash, dust, snowflakes).
• Telemetry logging for cloud history and periodic region forecast/state samples.

Changed

• Default constructor to support older versions of Forge
• Pressure/temperature limits tuned for more realistic values.
• Sunlight curve/seasonal tilt updated for stronger midday and deeper winter dimming.
• Forecast data now persists across world reloads instead of regenerating every time.
• Missing-forecast warnings now log once per biome to reduce spam.
• Storm siren behavior updated for severity 7 storm warnings and tornado proximity alerts.

Fixed

• Avoided loading client-only Aurora/Rainbows classes on servers by switching mixins to string targets.
• Prevented client-only mixins from loading on dedicated servers.
• Thermometer recipe output corrected.
• Cloud telemetry logging aligned with updated signatures.
• Fixed wind-bent particle mixin compatibility by replacing the switch expression with explicit checks.

Notes

AS ALWAYS UPDATING TO THIS VERSION REQUIRES DELETING YOUR OVERWORLD FOLDER (created by Project Atmosphere) TO AVOID ISSUES WITH THE NEW REGION SYSTEM.

• Go to your worlds folder and delete the "overworld" folder to allow the new region system to generate fresh regions.
• Note that this will reset the current forecast and could introduce desynced weather effects if the forecast isn't regenerated properly. (/temperature regenerate)
