Core Mechanics
Simulate cyclone genesis based on atmospheric fluid dynamics.
- Click INITIALIZE to generate a random disturbance.
- Use Settings to configure spawn points and environment.
- SST (Sea Surface Temp) drives intensification.

Wind Radii Structure
LAYER: STRUCTURAL ANALYSIS
Visualizes the extent of wind fields in four quadrants (NE, SE, SW, NW). Critical for determining the size and destructive potential of the system.
64 KT (Hurricane Force)
Core destruction zone
50 KT (Storm Force)
Severe weather zone
34 KT (Gale Force)
Outer circulation limit
Steering Flow (500hPa)
LAYER: SYNOPTIC FORCING
The primary driver of cyclone movement. Cyclones move around High Pressure ridges (clockwise in N.Hemisphere) and towards Low Pressure troughs.
Interactive Mode (God Mode)
Drag H and L handles on the map to reshape the subtropical ridge and alter the storm's path in real-time. Also, double click the map to place a high pressure manually.
850mb Relative Humidity
LAYER: THERMODYNAMICS
Indicates the moisture content available for the storm. Moisture is the fuel for convection.
Green Areas (>60%)
Favorable for development. Look for deep moisture wrapping marked as green on the humidity map.
Yellow/Brown Areas (>50%)
Dry Air Intrusion (SAL). Can choke the storm's convection and weaken the system.
Foehn Effect
When the moist airflow from a tropical cyclone crosses mountain ranges, it undergoes adiabatic warming during its descent on the leeward slope, forming dry and hot descending air currents that cause humidity to decrease.
100m Sustained Wind
LAYER: BOUNDARY LAYER
A high-resolution vector field showing the immediate surface circulation. Useful for pinpointing the exact Low Level Circulation Center (LLCC).
-
Visualizes inflow angles and convergence.
-
Helps identify when a wave organizes into a closed circulation (Depression stage).
The Dangerous Semicircle
In the Northern Hemisphere, the right side of a moving cyclone has the strongest winds. This is where the rotational wind speed adds to the storm's forward motion speed (V_rot + V_motion).
Forecast Track
LAYER: PREDICTION MODEL
Projected path based on current steering flows and beta-drift calculations. Click any track point to show the projected path at the point, and you can generate a warning map!
Center Line
Most probable track. Not a guarantee.
Cone of Uncertainty
The historical error margin. The center of the storm will remain within this cone 60-70% of the time. The storm can impact areas outside the cone.
Observation Post
LAYER: GROUND TELEMETRY
Deploy ground stations to gather localized telemetry. Essential for verifying satellite estimates and analyzing internal structure.
Deployment Strategy
- Open Settings menu.
- Input Callsign (Name), Longitude, and Latitude to deploy.
10-Min Sustained Wind
Standard meteorological measurement used by JMA. Smoothed data to filter out momentary gusts.
Weather & Pressure
Real-time Mean Sea Level Pressure (MSLP) and precipitation rate monitoring.
Base Reflectivity (Z)
Rain intensity visualization. Use Shortcut [R] to toggle. Critical for analyzing spiral rainbands and eyewall structure.
Radial Velocity (V)
Doppler effect. Use Shortcut [D] to toggle.
Blue/Green = Inbound,
Red/Pink = Outbound.
ICWC Agency Products
LAYER: ADVISORY GENERATION
The Independent Cyclone Warning Center (ICWC) is a tropical cyclone monitoring agency affiliated with STROM INC, providing tropical cyclone analysis and forecasting services worldwide. Accessible via the ICWC button when a track is selected.
Warning Graphic
Standard operational map showing past track, forecast cone, wind radii, and key city impacts.
Wind Speed Probability
Showing the cumulative probability of 34kt (Tropical Storm) or 64kt (Typhoon) winds at any location over the next 72 hours.
Station Observations
Retrieves historical telemetry logs for a specific time step. visualizes localized wind barbs, MSLP trends, and weather conditions relative to the storm's position.
