Natural Phenomenon Morning Glory Cloud

What is Morning Glory Cloud?

Morning Glory Cloud is a rare natural phenomenon consisting  of a low-level atmospheric solitary wave and associated cloud. Basically it's a roll cloud that's up to 1000 kilometers long. 1-2 kilometers high, and can move at speeds up to 60 kilometers per hour.

Where can we see Morning Glory Cloud?

Generically Morning Glory Cloud can happen in any places like America, Canada, Russia, Germany, Brazil, and other places. But the southern part of the Gulf of Carpentaria in Northern Australia is the only known location where it can be predicted and observed on a more or less regular basis due to configuration of land and sea in the area. 

How do Morning Glory Cloud form?

Wave for moist air from the sea meets drier air. The clouds form at the condensation level. The air descending at the back of the wave evaporates. This continual cycle results in the Morning Glory cloud


Morning Glory Cloud is not clearly understood because its rarity means it has little significance in terms of rainfall or climate. One of the main causes of most Morning Glory Cloud assurances in the mesoscale circulations associated with sea breezes that develop over the peninsula and the gulf.


  • Morning Glory Cloud can be observed from Burke town, Australia from September to early November.
  • Sometimes there is only one cloud, but sometimes there are up to ten consecutive roll clouds.
  • There are several waves and always aligned from east to west. The cause is a clash of air masses of different temperatures
