Morning Glory Cloud

The Morning Glory cloud is a boundary layer phenomenon. This phenomenon can be observed regularly in the North Australian Gulf of Carpentaria at spring time ( in the southern hemisphere ). It is a seemingly rolling cloud (roll cloud ), a so-called atmospheric soliton, of several hundred kilometers long, but only one to two kilometers in height, width, which can reach a speed of up to 60 km / hr. It has received after the time of arrival ( dawn ) on the coast of Queensland your name. The front page of the cloud go ahead strong updrafts, while the rear of the cloud drops and the air is turbulent. This creates an apparent, rolling motion. The cloud offers ideal conditions for sailing and hang gliding and is therefore the " Cloud Surfing" particularly popular.

Formation

If sea breezes meet from both sides of the Cape York Peninsula, they produce a convergence begins to wander as atmospheric wave. The moist air condenses on the forefront of this wave crest and forms the so characteristic cloud, which is supported by further east winds westward. The emergence of the Morning Glory cloud is not yet explored completely. Currently trying the basis of this fairly regularly occurring phenomenon clouds to develop predictive models for tropical storms.
