Additional notes
Altostratus undulatus is a type of
altostratus
cloud which is formed when a large layer of air is lifted into a zone of
wind shear aloft. The wind shear causes wave-like motion in the atmosphere,
which is reflected in the undulating appearance of the cloud. In
this case, sufficient moisture was present for the wave-like clouds to
appear as a continuous sheet. In cases of less moisture, an
observer may see "streaks" of clouds at the peaks of the waves
only.
These clouds indicate wind shear and turbulence aloft, but usually do
not produce any significant weather.
