roll clouds are usually formed by outflows of cold air from sea breezes or
cold fronts in the absence of thunderstorms.
A roll cloud is a low, horizontal, tube-shaped, and relatively rare type of
arcus cloud. They differ from shelf clouds by being completely detached from
other cloud features. Roll clouds usually appear to be "rolling" about a
horizontal axis. They are a solitary wave called a soliton, which is a wave
that has a single crest and moves without changing speed or shape. One of
the most famous frequent occurrences is the Morning Glory cloud in
Queensland, Australia. One of the main causes of the Morning Glory cloud is
the mesoscale circulation associated with sea breezes that develop over the
Cape York Peninsula and the Gulf of Carpentaria. However, similar features
can be created by downdrafts from thunderstorms and are not exclusively
associated with coastal regions.
