Humidifier (Cold Mist)
Two large cold humidifiers combined ≈ 30–60 L/day.
Updraft & Cloud Geometry
Convective plumes: 0.5–5 m/s. Without air motion, GCCN never reach cloud base.
Sahara LCL ≈ 4 km. Coastal = 1 km. Trade-wind cumulus = 1–2 km.
RH at cloud base. Above 30%+ supports cloud body > 1 km deep.

Comparison Modes
✓ CFL stable · ✓ vertical transport · ✓ Köhler activation · ✓ H² cloud-depth scaling · ✓ settling balance
Vertical Column View
Atmospheric Column Above Source
Ground · GCCN ascent · cloud base (s crosses Köhler threshold) · cloud top · coalescence zone. Vertical amplification = (H² × coalescence η).
ODE-CCT Real-time Metrics
Peak Relative Humidity
0%
Highest RH recorded in the current simulation grid.
Surface Mass Flux Ratio
9.7 × 10⁻¹⁴
Raw surface flux. Still hopeless at single-source.
Effective Rain Flux (altitude-corrected)
2.4 × 10⁻¹¹
Surface × vertical amplification. New key metric.
Cloud Depth Achieved
1.5km
Threshold: 1.5 km for warm rain, 3+ km for mixed-phase.
CCN at Cloud Base
0/cm³
Activated GCCN at altitude. Need > 10³/cm³ for rainfall enhancement.
Settling vs Updraft
w >> v_t
Droplets suspended while updraft stage active.
Rain Probability / hr
0.00%
P(rain) ∝ CCN_top × H² × updraft_probability × cumulus_presence
