| Zusammenfassung |
| This study uses in situ measurements collected during the FireFlux field
experiment to evaluate and improve the performance of the coupled
atmosphere–fire model WRF-SFIRE. The simulation by WRF-SFIRE of the
experimental burn shows that WRF-SFIRE is capable of providing realistic
head-fire rate of spread and vertical temperature structure of the fire
plume, and fire-induced surface flow and vertical velocities within the
plume up to 10 m above ground level. The simulation captured the changes in
wind speed and direction before, during, and after fire front passage, along
with the arrival times of wind speed, temperature, and updraft maxima, at
the two instrumented flux towers used in FireFlux. The model overestimated
vertical wind speeds and underestimated horizontal wind speeds measured at
tower heights above 10 m. It is hypothesized that the limited model spatial
resolution led to overestimates of the fire front depth, heat release rate,
and updraft speed. However, on the whole, WRF-SFIRE simulated fire plume
behavior that is consistent with FireFlux observations. The study suggests
optimal experimental pre-planning, design, and execution strategies for
future field campaigns that are intended to evaluate and develop
further
coupled atmosphere–fire models. |
