Vortices are almost always present in the wildland fire environment and can sometimes interact with the fire in unpredictable ways,\r\ncausing extreme fire behavior and safety concerns. In this paper, the current state of knowledge of the interaction of wildland fire\r\nand vortices is examined and reviewed. A basic introduction to vorticity is given, and the two common vortex forms in wildland\r\nfire are analyzed: fire whirls and horizontal roll vortices. Attention is given to mechanisms of formation and growth and how this\r\ninformation can be used by firefighters.
