| description | We present a case study of a noctilucent cloud (NLC) display appearing on
10-11 August 2000 over Northern Sweden. Clear wave structures were visible
in the clouds and time-lapse photography was used to derive the parameters
characterising the gravity waves which could account for the observed NLC
modulation. Using two nearby atmospheric radars, the Esrange MST Radar data
and Andoya MF radar, we have identified gravity waves propagating upward
from the upper stratosphere to NLC altitudes. The wave parameters derived
from the radar measurements support the suggestion that gravity waves are
responsible for the observed complex wave dynamics in the NLC. |
