Pyrocumulus Satellite Plume & Thermal Dynamics Simulator

EVENT: Widemouth 2 Fire (UT)

GOES-19 Band 7 (3.9µm) SWIR Hotspot

Lifting Condensation (LCL) 2,400 m

Plume Top Altitude 11,200 m

GOES-19 Band 7 SWIR Temp 368 K (95°C)

Cloud Top LWIR Temp 223 K (-50°C)

Eruption State

🔥 PyroCb Triggered

Thermodynamic & Fire Controls

Ground Fire Heat Flux 8,500 MW

Ambient Moisture (Mixing Ratio) 8.5 g/kg

Lapse Rate (Troposphere) 8.2 °C/km

Upper Wind Shear 18 kts

Atmospheric Physics: Intense surface fire heat creates powerful buoyant thermals. As the plume ascends past the LCL (Lifting Condensation Level), moisture condenses into Pyrocumulus. If thermal power exceeds tropopause stability, explosive PyroCb overshooting tops punch into the stratosphere.
