Effects of High‐Density Gradients on Wildland Fire Behavior in Coupled Atmosphere‐Fire Simulations

Journal of Advances in Modeling Earth Systems, Volume 14, Issue 11, November 2022., 2022
Abstract Coupled atmosphere‐fire modeling is recognized as a relevant approach for the representation of the interaction between a wildland fire and local meteorology at landscape scales. The atmospheric model component used in the coupled system is based on several approximations, which are adopted for computational efficiency or physical processes ...

Tracking Wildfires With Weather Radars

Journal of Geophysical Research: Atmospheres, Volume 127, Issue 11, 16 June 2022., 2022
Abstract There is a need for nowcasting tools to provide timely and accurate updates on the location and rate of spread (ROS) of large wildfires, especially those impacting communities in the wildland urban interface. In this study, we demonstrate how fixed‐site weather radars can be used to fill this gap.

Analysis of methods for assimilating fire perimeters into a coupled fire-atmosphere model

Frontiers in Forests and Global Change, 2023
Correctly initializing the fire within coupled fire-atmosphere models is critical for producing accurate forecasts of meteorology near the fire, as well as the fire growth, and plume evolution.

Forecasting wildfires in major forest types of India

Frontiers in Forests and Global Change, 2022
Severity of wildfires witnessed in different parts of the world in the recent times has posed a significant challenge to fire control authorities. Even when the different fire early warning systems have been developed to provide the quickest warnings ...

Experimental Design of a Prescribed Burn Instrumentation

Atmosphere, 2018
Observational data collected during experiments, such as the planned Fire and Smoke Model Evaluation Experiment (FASMEE), are critical for evaluating and transitioning coupled fire-atmosphere models like WRF-SFIRE and WRF-SFIRE-CHEM into operational use.

Wildfire Impact on Environmental Thermodynamics and Severe Convective Storms

Geophysical Research Letters, Volume 46, Issue 16, Page 10082-10093, 28 August 2019., 2019
Abstract Wildfires are extreme events associated with weather, climate, and environment and have been increasing globally in frequency, burn season length, and burned area. It is of great interest to understand the impacts of wildfires on severe convective storms through releasing heat and aerosols into the atmosphere.

An Accurate Fire‐Spread Algorithm in the Weather Research and Forecasting Model Using the Level‐Set Method

Journal of Advances in Modeling Earth Systems, Volume 10, Issue 4, Page 908-926, April 2018., 2018
Abstract The level‐set method is typically used to track and propagate the fire perimeter in wildland fire models. Herein, a high‐order level‐set method using fifth‐order WENO scheme for the discretization of spatial derivatives and third‐order explicit Runge‐Kutta temporal integration is implemented within the Weather Research and Forecasting model ...

Assessing wildfire dynamics during a megafire in Portugal using the MesoNH/ForeFire coupled model

Quarterly Journal of the Royal Meteorological Society, Volume 152, Issue 775, January 2026 Part B.
Weather conditions affect megafires by inducing different fire behaviors over several days or weeks. The coupled MesoNH/ForeFire code was used to represent the dynamics of fire generating pyro‐convective clouds. To advance the understanding of wildfire dynamics, high‐resolution coupled fire–atmosphere modeling was employed.
