We demonstrate how to modify the model of the moving foci, developed for condensed media for explanation of experiments on filamentation of the high-power subpicosecond laser pulses in air. This modified model allows one to consider the gas ionization in the high-intensity laser field. The numerical simulation based on this model allows us to explain not only the filamentation phenomenon, but also the accompanying effects such as refocusing and the conical emission.
