**Leader**: Theodore M. Giannaros
**Co-leader**: Research Associate
**Contributors**: Vassiliki Kotroni, Antonis Bezes
**WP start**: 01/08/2022
**WP end**: 30/11/2023
Objectives
----------
To explicitly account for the concept of atmospheric instability in a coupled fire-atmosphere modeling system by developing a wind gust parameterization.
Description of Work
-------------------
This WP will deliver an upgraded version of the coupled fire-atmosphere WRF-Fire modeling system, by developing a wind gust parameterization scheme for the explicit consideration of the effect of atmospheric stability on fire spread. The parameterization will be evaluated with respect to its effect on fire spread prediction. Numerical experiments will be also conducted for studying the effect of explicitly considering gustiness (and thus atmospheric instability) on the generation of transient fire phenomena, such as convective plumes and horizontal roll vortices. The upgraded model code will be distributed to the development team and user community of WRF-Fire, while it be operationally deployed at NOA.
