At the time of landing, these firebrands can start secondary fires far away from the main burning unit. This phenomenon is called spotting and the secondary fires are referred to as spot fires. Here, we first present numerical evidence that atmospheric traveling waves can increase the spotting distance by at least an order of magnitude compared to unidirectional wind conditions. We then present theoretical results explaining this numerical observation.
