- Performance checks help maintain smooth simulation behavior during intense weather events.
Weather Sandbox how to make a hurricane: Core Setup
To make a hurricane-style system in Weather Sandbox, focus on building organized circulation rather than creating a large area of random turbulence. The simulation includes real-world sounding presets, adjustable resolution, weather tools, display modes, and a movable simulation view. These features let you establish a broad environment first, then strengthen the storm’s rotating structure.
The available documentation does not identify a dedicated “hurricane” button or named hurricane preset. Treat this as a controlled storm-building exercise: select a suitable real-world sounding, use a realistic vertical resolution, give the circulation enough horizontal room, and monitor the result through the display modes.

Realistic Forcing
Choose a real-world sounding from the preset menu before building the storm. This gives the simulation an atmospheric starting point instead of an entirely empty setup.
Vertical Structure
Set vertical resolution to approximately 300 when realism is the priority. This is the recommended value for more realistic results.
Room to Organize
Use a larger horizontal resolution when possible. More horizontal space allows stronger converging winds and longer-lasting cells to develop.
| Setup Element | Recommended Approach | Why It Matters |
|---|---|---|
| Forcing | Select a real-world sounding | Establishes a realistic atmospheric starting point |
| Vertical resolution | Around 300 | Supports more realistic vertical structure |
| Horizontal resolution | Increase when performance allows | Gives converging winds room to organize |
| View mode | Use wind, humidity, or cloud displays | Makes circulation and storm structure easier to inspect |
| Performance | Prefer a dedicated GPU | Helps maintain real-time simulation behavior |
Start with a broad, stable environment and make gradual changes. A compact area of intense activity is easier to interpret after the surrounding wind field has become organized.
Step-by-Step Hurricane-Style Storm Workflow
The following workflow turns the available simulation controls into a repeatable storm-building method. It is designed for experimentation rather than a fixed recipe, because the final result depends on the selected sounding, resolution, brush actions, and simulation timing.
Load a Realistic Starting Environment
Open the preset menu and select a real-world sounding. Begin with a clean setup so you can identify which changes come from your own tools and which conditions were already present in the forcing data.
Set the Simulation Resolution
Use a vertical resolution near 300 for a more realistic baseline. Increase horizontal resolution when your hardware can maintain responsive performance, since wider spaces can support stronger converging winds and longer-lived cells.
Create Broad Convergence
Select the appropriate tool and use the left mouse button to apply it. Build a broad region of converging motion instead of concentrating every action in one small area. Hold Ctrl or Command to invert a tool action when you need to correct the field.
Shape the Rotation
Watch the velocity vectors and wind-related display modes while adjusting the storm. Use smaller brush actions to refine the circulation, and zoom or pan the simulation so the developing structure remains visible.
Run, Pause, and Inspect
Press Space to pause or resume the simulation. Allow the circulation to evolve, pause when the structure becomes difficult to read, and compare the wind, humidity, cloud, and other available displays before making another change.
| Stage | Main Action | Useful Control |
|---|---|---|
| Start | Load a real-world sounding | Preset menu |
| Build | Apply broad converging motion | Left mouse button |
| Correct | Reverse an unwanted action | Left Ctrl or Command |
| Inspect | View circulation and structure | Display modes, velocity vectors |
| Control time | Pause or resume evolution | Space Bar |
The mouse wheel changes zoom, while holding B allows it to change brush size. Pressing B twice toggles a whole-width brush, which can be useful for broad environmental adjustments. Use that option carefully: large changes can overwhelm the smaller circulation you are trying to preserve.
Do not repeatedly apply the strongest available brush action to the same small area. If the circulation becomes chaotic, invert the last action, reduce the brush size, or reload the saved setup before rebuilding more gradually.
Controls for Building and Reading Circulation
A hurricane-style storm is easier to create when you separate environmental setup from visual inspection. Weather Sandbox provides several display and navigation controls that help you understand whether the storm is becoming organized, too weak, or overly turbulent.
Use the velocity-vector overlay to study wind direction and movement. Humidity and cloud-density displays can help identify where moisture and visible storm structure are developing. Weather stations and the sounding graph provide additional ways to inspect conditions without relying only on the main visual field.
| Control or Key | Function | Best Use During Storm Setup |
|---|---|---|
| Left mouse button | Use the selected tool | Apply or shape atmospheric changes |
| Ctrl or Command | Invert tool action | Remove or reverse an adjustment |
| Mouse wheel | Zoom in or out | Inspect storm scale and structure |
| B + mouse wheel | Change brush size | Move between broad and precise edits |
| B twice | Toggle whole-width brush | Make wide environmental adjustments |
| Tab | Show or hide velocity vectors | Read wind direction and convergence |
| C | Humidity and cloud-density display | Inspect moisture and cloud structure |
| G | Show or hide sounding graph | Review atmospheric forcing |
| N | Show or hide weather stations | Add observational reference points |
| Space Bar | Pause or resume | Freeze the system for close inspection |
Wind View
Use velocity vectors to check whether motion is converging and rotating or simply spreading outward.
Humidity View
Compare moisture concentration with the developing circulation. This can reveal whether the storm core is supported by the surrounding environment.
Cloud View
Use cloud-density information to distinguish visible storm structure from isolated wind changes.
Sounding Graph
Inspect the selected forcing and compare the atmospheric profile with the storm’s behavior.
A convincing hurricane-style result should show organized motion across a broad area, not just a bright or intense patch in one display. Switch views regularly so visual effects do not replace physical interpretation.
Resolution, Performance, and Troubleshooting
Simulation scale has a direct effect on how much room a storm has to develop. The game’s guidance recommends a vertical resolution of 300 for realistic results and notes that larger horizontal resolutions can support stronger converging winds and longer-lasting cells. Higher settings may require more graphics performance, so adjust them according to responsiveness.
Performance is mostly GPU dependent. A GTX 1070 or better is recommended for real-time play, and laptops with dedicated graphics should be checked to ensure the browser is using the dedicated GPU rather than integrated graphics. Fullscreen mode with F11 can also make the simulation easier to monitor.
| Problem | Likely Cause | Practical Adjustment |
|---|---|---|
| Storm disappears quickly | Limited horizontal room or weak organization | Increase horizontal resolution or rebuild broader convergence |
| Circulation looks chaotic | Brush actions are too concentrated | Reduce brush size and apply fewer corrections |
| Simulation feels slow | Resolution or display load is high | Lower resolution, hide extra overlays, or check GPU usage |
| Structure is hard to read | View is too zoomed out or cluttered | Zoom in, pause with Space, and inspect one display at a time |
| Laptop performance is poor | Browser uses integrated graphics | Switch the browser to the dedicated GPU |
| Wind direction is unclear | Velocity vectors are hidden | Press Tab to show the vector overlay |
Before You Start:
- Select a real-world sounding from the preset menu
- Set vertical resolution near 300
- Choose a horizontal resolution your hardware can handle
- Confirm the browser is using the dedicated GPU when available
- Enable fullscreen mode with F11 for easier monitoring
A responsive simulation is more useful than maximum settings that prevent careful adjustments. Choose the highest resolution that still lets you pause, inspect, and correct the storm comfortably.
Refinement Checklist and Advanced Practice
Once the storm begins to organize, avoid changing several variables at once. Pause the simulation, inspect the current circulation, make one adjustment, and then resume. This makes it easier to understand which tool action improved the storm and which one weakened it.
Saving and reloading are also valuable for experimentation. The controls include L to reload from a save file, giving you a recovery point when an experiment produces unwanted turbulence. If you want to compare different approaches, preserve a stable setup before attempting more aggressive changes.
| Refinement Goal | What to Watch | Suggested Practice |
|---|---|---|
| Broader circulation | Wind vectors across the full area | Work at a larger horizontal scale |
| Stronger convergence | Inward movement toward the storm region | Apply gradual environmental changes |
| Longer duration | Whether the cell persists after pausing and resuming | Avoid overloading one small area |
| Clearer storm structure | Humidity and cloud-density patterns | Compare C mode with wind displays |
| Better control | Ability to identify each change | Pause often and alter one variable at a time |
Use the official 2D Weather Sandbox simulation as the primary reference for the live controls and available interface. The official page also links to community and creator resources, including YouTube and Discord, which can help you compare techniques beyond the basics covered here.
Build a stable broad circulation first, then refine its inner structure. This produces clearer experiments than trying to force a finished hurricane in a single brush pass.
Q: Is there a dedicated hurricane preset in Weather Sandbox?
The available documentation lists real-world sounding presets but does not identify a dedicated hurricane button or named hurricane preset. Build the storm through forcing, resolution, convergence, and controlled adjustments.
Q: What vertical resolution should I use for a hurricane-style storm?
A vertical resolution of approximately 300 is recommended when realistic results are the priority. Higher or lower settings may change performance and visual behavior.
Q: Why should I increase horizontal resolution?
Larger horizontal resolutions provide more room for converging winds to develop. That extra space can support stronger circulation and longer-lasting cells when your hardware remains responsive.
Q: Which displays help me judge whether the storm is organized?
Velocity vectors are useful for wind direction and convergence. Humidity and cloud-density displays help you inspect moisture and visible structure, while the sounding graph shows the selected atmospheric forcing.
