cloud surfing

"The Morning Glory cloud is one of the most spectacular meteorological phenomena in the world. It is quite rare as it is usually only observed in Northern Australia's Gulf of Carpentaria. A Morning Glory cloud can best be described as a roll cloud that can be up to 1000 kilometers long, 1 to 2 kilometers high, and can move at speeds up to 40 kilometers per hour. The morning glory is often accompanied by sudden wind squalls, intense low-level wind shear, a rapid increase in the vertical displacement of air parcels, and a sharp pressure jump at the surface. In the front of the cloud, there is strong vertical motion that transports air up through the cloud and creates the rolling appearance, while the air in the middle and rear of the cloud becomes turbulent and sinks. The cloud can also be described as a Solitary wave or a Soliton, which is a wave that has a single crest and moves without changing speed or shape."
