Abstract
A thin rotor cloud was observed on the lee side of Penny Ice Cap in th e Canadian Arctic on 21 April 1996. The cloud consisted of thin cirrif orm layers, so that its motion was clearly observed. By means of time- lapse camera photography, the velocity of the cloud rotation was estim ated to be around 2 m s(-1). It is.suggested that the existence of a h igh humidity layer at the bottom of an inversion layer is a key factor for the formation of the thin rotor cloud.
