Propagation of short and intense laser beams in the atmosphere is considered for the purpose of identifying the temporal compression. The conditions and validity of linear and nonlinear compression theories are discussed. The effects of chirping and pulse power in the preionization regime are deliberated. The fact that the linear theory cannot explain the pulse compression in the atmosphere is presented.
