Ultraviolet spectrophotometry of two dwarf novae, CN Ori and RX And, at various phases of their outburst cycles, confirms that the far UV flux increases dramatically about 1-2 days after the optical outburst begins. At this time the UV spectral line profiles indicate the presence of a high velocity wind. The detectability of the wind depends more on the steepness of the spectrum, and thus on the flux in the extreme ultraviolet, than on the value of the far UV luminosity. The UV continuum during outburst consists of (at least) two components, the most luminous of which is located behind the wind and is completely absorbed by the wind at the line frequencies. Several pieces of evidence suggest that the UV emission lines that are observed in many cataclysmic variables during quiescence originate in a location different from that of the wind in the binary, and are affected little by the outburst.
