摘要：

A sudden transient increase of the solar ultraviolet (UV) radiation was detected with a ground-based photometer in Madrid (Spain, 41degreesN, 3degreesW) on 25 November 1996 (Cordoba et al., 2000. UV-B irradiance at Madrid during 1996, 1997 and 1998. J. Geophys. Rcs. 105 (D4) (2000) 4903-4906). The data obtained by the TOMS satellite instrument revealed that this event was related to a reduction of the total ozone column values. This low ozone episode has been analysed. The ozone decrease was accompanied by a reduction of air temperature in the lower stratosphere. The anti-correlation between total ozone and air parcel height along the three-dimensional isentropic back-trajectories suggests that the adiabatic uplift of air contributed significantly to both the ozone and the temperature decreases observed. The uplift could be caused by the propagation into the lower stratosphere of the high-pressure cell located over the mid-Atlantic region. (C) 2002 Elsevier Science Ltd. All rights reserved.
