This series of images is the continuation of chapter Leewave
Clouds Series I. There different examples are shown and the
mechanism of cloud formation is roughly explained. Here only special
features are described.
LWclouds14.jpg: This image was taken at 6:57 a.m. in the morning.
Though it was made with high sensitivity (adjusted to 3200 ASA),
the time of exposure was not appropriate (1/4000 s, Lens Aperture
11 und 200 mm objective). Therefore the exposure is all in all only
low and the CCD chip of the SLR is dominated by electronic noise.
This results in many pixels which do not fit with their "neighbourhood"
so that the image seems to be "grained".
LWclouds16.jpg: The same scene at 8:21 a.m. taken with well adjusted
LWclouds22,24,28.jpg etc.: Here the Leewave clouds are located directly
above or near the Monte Rosa Massive which is approximately 60 km
away from the location of the photographer.
LWclouds26,27,30.jpg etc.: Here it is especially eye-catching that
the cloud layers are arranged like piles of plates. Thereby the
weak turbulent flow inside the Leewave clouds becomes visible.
