Scientific paper

Models are presented for the effects of a stellar wind on the UV and soft X-ray spectra of cataclysmic variables (CVs). It is shown that P Cygni absorption lines observed from many CVs are consistent with the existence of a strong wind, and that such a wind can also account for the soft X-ray upper limits if the wind mass loss rate is ≡10-8M_sun;yr-1. The implications of such a wind for the CV momentum and energy budget are discussed.
