wind_speed_msnumberdefault: 50–30 (step 0.5)Reference wind speed at 10m height (m/s)
Higher reference speeds increase the likelihood of uncomfortable or dangerous conditions, especially at building corners and in open plazas. Sheltered courtyards are less sensitive.
wind_direction_degnumberdefault: 2700–360 (step 10)Prevailing wind direction in degrees (0=N, 90=E, 180=S, 270=W)
Wind direction determines which building faces are exposed and which streets act as wind channels. Diagonal winds (45°/135°) often produce the worst corner acceleration.
comfort_criterionselectdefault: lawsonlawson | davenport | nwiAssessment criterion for pedestrian comfort classification
Lawson criteria are widely used in the UK and Netherlands. Davenport applies a simpler probabilistic threshold. NWI (Netherlands Wind Index) is most stringent for public space design approval.
analysis_seasonselectdefault: annualannual | summer | winterSeason affects weighting of wind frequency and comfort thresholds
Annual gives a balanced assessment. Summer highlights discomfort in outdoor dining and park areas. Winter identifies exposure risk for pedestrians on shopping streets.
Default settings represent a moderate prevailing westerly wind. Run to see the baseline comfort map, then explore: - Increase wind speed to simulate exposed coastal or hilltop sites - Change wind direction to 45° or 135° to test diagonal wind exposure - Switch comfort criterion to NWI for planning-permission-grade assessment - Filter the results table for 'uncomfortable' or 'dangerous' zones to prioritise design interventions
