Synthetic Diagnostic Sandbox

Simplified Lee Viewer

This standalone viewer lets you filter the synthetic hill experiment, inspect one scenario at a time, and see how the toy diagnostics respond to changing wind strength, stability, and low-level shear. The lee panel is a schematic visualization, not a flow solver.

Terrain Setup

One asymmetric ridge extruded along its axis, viewed in oblique 3D. Wind arrows show how the flow impinges on the ridge at the configured ridge-relative angle — 0 degrees runs along the ridge, 90 degrees is fully cross-ridge from the windward side. The viewer wind range is limited to 0-10 m/s and the headline hazard values are paragliding-scaled display scores.

Schematic Lee Cross-Section

Schematic cross-section around the ridge. Warmer colors mark where this toy diagnostic expects stronger lee turbulence, and the dashed line shows the approximate downwind lee extent. The mid-range of the palette is intentionally boosted so moderate setups remain visible. Rotor pockets now follow the trapped-wave plus inversion logic rather than the old Richardson-only proxy. This is a visualization layer, not a fluid simulation.

Weak Moderate Strong

Selected Scenario

Hazard Score

Paragliding-scaled display score built on top of the raw lee-hazard model.

Rotor Risk

Paragliding-scaled display score derived from the raw rotor proxy.

Lee Extent

Synthetic downwind reach of the active lee.

Peak Zone

Strongest turbulence pocket in this toy cross-section.

Wave Score

Bulk wave-support indicator.

Trap Proxy

Terrain-scale k sits between lower and upper Scorer values.

Froude Number

Blocked versus overflow tendency.

Vertical Wind Profile

Selected scenario cross-ridge wind component versus altitude. Sheared profiles should lean farther right near and above ridge top, while ridge-parallel flow should collapse this profile toward zero.

Scorer Structure

Selected scenario Scorer parameter profile. The shaded bands mark the lower and upper averaging layers, and the dashed line marks the terrain-scale k^2 reference used in the trapped-wave proxy.

Scenario Comparison

Each point is one scenario. Horizontal position shows Froude number, vertical position shows hazard score, and color marks the vertical wind-profile type.
