Weather Sandbox old version: Core Features
The Weather Sandbox old version is an interactive 2D weather simulation built around atmospheric movement, cloud formation, wind flow, and environmental visualization. It is best approached as a scientific sandbox rather than a conventional level-based game. You create conditions, observe the result, and adjust the simulation to study how the system responds.
The simulation supports real-world sounding presets that act as forcing data. A sounding provides an atmospheric profile for the simulation, giving each preset a different starting structure. You can also load a save file when you want to return to a previous setup instead of rebuilding the scene manually.
Atmospheric Setup
Choose a real-world sounding and use it as the simulation's forcing profile.
Visual Analysis
Switch between cloud density, humidity, air quality, velocity, and other display modes.
Interactive Tools
Paint conditions with the selected tool, invert actions with Ctrl, and adjust brush size with B.
| Feature | Purpose | Best Use |
|---|---|---|
| Sounding preset | Supplies atmospheric forcing | Start a repeatable scenario |
| Save file | Restores a previous simulation | Continue experiments |
| Display modes | Reveals hidden atmospheric data | Compare weather structures |
| Weather stations | Adds local observation points | Inspect conditions by location |
| Flight mode | Adds a basic aircraft interaction layer | Explore the simulation from above |
Begin with a preset before changing multiple variables. A stable baseline makes it easier to identify which tool or resolution setting caused a visible change.
For the original browser experience, use the 2D Weather Sandbox page. The available interface may vary over time, so this guide focuses on the in-game controls and behavior associated with the older version.
Resolution and Performance Setup
Resolution is one of the most important choices in the old interface. The game’s guidance identifies a vertical resolution of 300 as a strong balance for realistic results. Increasing horizontal resolution can support stronger converging winds and longer-lasting cells, but it also increases the workload placed on the computer.
Performance is primarily GPU-dependent. A dedicated graphics processor is recommended for real-time use, and laptops may need manual checking to ensure the browser uses the dedicated GPU instead of integrated graphics.
| Setting | Practical Effect | Recommended Approach |
|---|---|---|
| Vertical resolution | Changes atmospheric detail from bottom to top | Start near 300 for realistic results |
| Horizontal resolution | Supports larger wind structures and cells | Increase gradually when performance allows |
| Iterations per second | Controls simulation update speed | Use PgUp and PgDn to tune responsiveness |
| Fullscreen mode | Gives the simulation more usable space | Press F11 for a clearer workspace |
| GPU selection | Affects real-time performance | Confirm the browser uses the dedicated GPU |
Choose a Baseline
Select a sounding preset and avoid changing several major settings at once. This provides a clear reference for later experiments.
Set Vertical Detail
Use a vertical resolution close to 300 when realism is the priority. Lower values may improve speed, while higher values demand more processing.
Test Horizontal Scale
Increase the horizontal resolution in small increments. Watch for stronger convergence, longer-lasting cells, and any reduction in responsiveness.
Tune Simulation Speed
Use PgUp to increase iterations per second or PgDn to reduce them. Choose the fastest setting that remains easy to observe.
High resolution can make the simulation less responsive. If movement becomes uneven, reduce horizontal detail or iterations before changing other settings.
A practical workflow is to establish the atmospheric profile first, then adjust resolution, and only afterward experiment with tools. This order avoids confusing a performance change with a weather-system change.
Controls and Display Modes
The old control scheme combines mouse actions with keyboard shortcuts. The left mouse button applies the selected tool, while holding Ctrl performs the inverted action. The middle mouse button moves the simulation view, and the mouse wheel zooms the scene. Holding B while scrolling changes brush size.
| Input | Action | Notes |
|---|---|---|
| Left mouse button | Use selected tool | Hold Ctrl for the inverted action |
| Middle mouse button | Drag the simulation view | Useful when inspecting a large field |
| Mouse wheel | Zoom the view | Hold B to change brush size |
| Space | Pause or resume | Helpful when comparing a developing cell |
| Arrow keys | Move the view | Right Ctrl enables slower panning |
| Tab | Show or hide velocity vectors | Useful for tracking wind direction |
| H | Show or hide the interface | Creates a cleaner observation view |
| V | Reset the view | Returns the camera to its default position |
Display keys from 1 through 9 provide alternate visual modes. Additional keys expose specific atmospheric information:
- K toggles the air quality display.
- C shows relative humidity and cloud density.
- D shows or hides droplets.
- G shows or hides the sounding graph.
- N shows or hides weather stations.
- M adds or removes weather stations.
- Esc removes the active tool and activates the flashlight-style view.
Navigation
Use middle-click dragging, arrow keys, zoom controls, and V to move through the field efficiently.
Inspection
Use Tab, C, K, D, G, and N to examine different parts of the atmospheric model.
Editing
Select a tool, paint with the left mouse button, and use Ctrl when you need the opposite effect.
Pause with Space before switching display modes. A frozen frame makes it easier to compare cloud density, humidity, velocity vectors, and droplet placement.
Touch input is described as basic in the older interface. For precise work, a mouse and keyboard provide more reliable control, especially when changing brush size or using modifier keys.
Flight Mode and Advanced Interactions
The old version includes a flight simulator mode that lets you interact with the weather field from an aircraft perspective. Press A to activate it. The vertical mouse position controls the elevator, while the arrow keys adjust throttle. Press F to toggle camera following, Shift to toggle landing gear, and Caps Lock to enable autopilot.
| Shortcut | Flight Function | Practical Use |
|---|---|---|
| A | Toggle flight simulator mode | Enter or leave aircraft interaction |
| F | Toggle camera following | Keep the aircraft centered |
| Shift | Toggle landing gear | Manage the aircraft state |
| Caps Lock | Toggle autopilot | Maintain automated flight behavior |
| Arrow keys | Adjust throttle or move view | Depends on the active mode |
| Z | Drop water from the aircraft | Extinguish fires in the simulation |
| . | Apply brakes | Reduce aircraft movement |
| / | Toggle engine | Control engine state |
The aircraft can also participate in environmental interactions. Pressing Z drops water to extinguish fires, making flight mode useful for testing how an intervention affects a changing scene. The mode is not required for studying atmospheric behavior, but it adds another way to observe and influence the sandbox.
Use flight mode after you understand the normal camera and tool controls. Otherwise, aircraft movement can make it harder to determine whether a change came from the weather system or from your own input.
Before Running a Test:
- Select a sounding preset
- Set vertical resolution near 300
- Confirm the browser is using the preferred GPU
- Open the display modes needed for observation
- Save the scene before making major changes
Change one major variable at a time, pause often, and record the visible result. This produces clearer comparisons than rapidly combining several tools.
A useful experiment might begin with a preset, continue at moderate resolution, and use velocity vectors plus cloud density as the primary observations. After the scene is understood, add weather stations or try flight mode for a second perspective.
Weather Sandbox old version FAQ
The old interface rewards patient observation. Most confusion comes from mixing camera controls, display overlays, simulation speed, and atmospheric tools without first establishing a baseline.
| Goal | Recommended Controls | Why It Helps |
|---|---|---|
| Inspect wind flow | Tab, pause with Space | Makes vector movement easier to compare |
| Study clouds | C, G, moderate resolution | Connects cloud density with the sounding profile |
| Improve responsiveness | Reduce resolution, use PgDn | Lowers processing demand |
| Explore a large scene | Middle-click, arrows, zoom | Keeps navigation separate from tool use |
| Test firefighting | A, Z, flight controls | Adds a direct environmental interaction |
