Short summary
With simulations, we studied the impact of fire-induced circulations on the atmosphere and the factors governing these circulations. The results showed that two parts of the circulations, the up- and downdrafts, altered the vertical structure of the atmosphere ahead of the fire. Furthermore, we found that the wind speed in the direction of the circulation determines whether a circulation can develop. Further research is needed to study how fire-induced circulations affect the fire behaviour.
