Modeling Multiple-Core Updraft Plume Rise for an Aerial Ignition Prescribed Burn by Coupling Daysmoke with a Cellular Automata Fire Model

open access: yesAtmosphere, 2012
Smoke plume rise is critically dependent on plume updraft structure. Smoke plumes from landscape burns (forest and agricultural burns) are typically structured into “sub-plumes” or multiple-core updrafts with the number of updraft cores depending on ...

Rise and deflection of mantle plume tails

open access: yesGeochemistry, Geophysics, Geosystems, 2008
Experimental observations by Kerr and Mériaux (2004) of the deflection of thermal plume tails by an imposed background shear are reanalyzed using a corrected velocity profile. The deflected plumes are found to be accurately described by a constant vertical rise velocity (equation (14)) that depends primarily on the plume buoyancy flux and the ambient ...

Modeling Smoke Plume-Rise and Dispersion from Southern United States Prescribed Burns with Daysmoke

open access: yesAtmosphere, 2011
We present Daysmoke, an empirical-statistical plume rise and dispersion model for simulating smoke from prescribed burns. Prescribed fires are characterized by complex plume structure including multiple-core updrafts which makes modeling with simple ...

Important parameters for smoke plume rise simulation with Daysmoke

open access: yesAtmospheric Pollution Research, 2010
Daysmoke is a local smoke transport model and has been used to provide smoke plume rise information. It includes a large number of parameters describing the dynamic and stochastic processes of particle upward movement, fallout, fluctuation, and burn ...

Incorporating an Interactive Fire Plume‐Rise Model in the DOE's Energy Exascale Earth System Model Version 1 (E3SMv1) and Examining Aerosol Radiative Effect

open access: yesJournal of Advances in Modeling Earth Systems, 2023
The vertical distribution of biomass burning aerosol (BBA) is important in regulating their impacts on weather and climate. The plume‐rise process affects the injection height of BBA and interacts with the air parcel lifting and cloud processes. However,

Effects of Fire Diurnal Variation and Plume Rise on U.S. Air Quality During FIREX‐AQ and WE‐CAN Based on the Multi‐Scale Infrastructure for Chemistry and Aerosols (MUSICAv0)

open access: yesJournal of Geophysical Research - Atmospheres, 2022
We analyze the effects of the diurnal cycle of fire emissions (DCFE) and plume rise on U.S. air quality using the MUSICAv0 (Multi‐Scale Infrastructure for Chemistry and Aerosols Version 0) model during the FIREX‐AQ (Fire Influence on Regional to Global ...

Numerical simulation of smoke natural filling in ultra-thin and tall atrium

open access: yesCase Studies in Thermal Engineering, 2021
In this paper, the natural filling law of smoke in ultra-thin and tall atrium was studied by means of numerical simulations. The results show that, the axial plume velocity of the ultra-thin and tall atrium has a good exponential function dependence on ...

An emergency response model for the formation and dispersion of plumes originating from major fires (BUOYANT v4.20) [PDF]

open access: yesGeoscientific Model Development, 2022
A mathematical model called BUOYANT has previously been developed for the evaluation of the dispersion of positively buoyant plumes originating from major warehouse fires. The model addresses the variations of the cross-plume integrated properties (i.e.,

Plume–ridge interactions: ridgeward versus plate-drag plume flow [PDF]

open access: yesSolid Earth, 2023
The analysis of mid-ocean ridges and hotspots that are sourced by deep-rooted mantle plumes allows us to get a glimpse of mantle structure and dynamics.
