Unusual appearance of mother-of-pearl clouds above El Calafate, Argentina (50°21′S, 72°16′W)
Visual observations from the ground and from a glider soaring in the lowermost stratosphere revealed the existence of stratospheric mother-of-pearl clouds above El Calafate in the lee of the Andes on 11 September 2019. The appearance of these clouds is rather unusual considering the time – end of th...

Visual observations from the ground and from a glider soaring in the lowermost stratosphere revealed the existence of stratospheric mother-of-pearl clouds above El Calafate in the lee of the Andes on 11 September 2019.

This paper presents the available observations and describes the overall meteorological situation that was related to the earliest sudden stratospheric warming recorded so far in the Southern Hemisphere.
