formations have been noticed here since ancient times. The local Garrwa Aboriginal people called it kangólgi. Royal Australian Air Force pilots first reported this phenomenon in 1942. The Morning Glory cloud of the Gulf of Carpentaria has been studied by multiple teams of scientists since the early 1970s. The first studies were published by Reg H. Clarke (University of Melbourne). Multiple studies have followed since then, proposing diverse mathematical models explaining the complex movements of air masses in the region. Atmospheric Conditions One of the main contributors for the formation of the morning glory clouds is the mesoscale circulations associated with a difference in sea breezes that develop over the Peninsula and the Gulf. On the large scale, Morning Glories are usually associated with frontal systems crossing central Australia and high pressure in northern Australia. Locals have noted that the Morning Glory is likely to occur when the humidity in the area is high, which provides moisture for the cloud to form, and when strong sea breezes have blown the preceding day. The following is a summary of the conditions that cause the Morning Glory cloud to form in the Gulf of Carpentaria (after hypothesis of R.H.Clarke, as described in 1981). First, Cape York which is the peninsula that lies to the east of the gulf, is large enough that sea breezes develop on both sides. During the day, the breeze from the Coral Sea coast blows in from the east and the breeze from the gulf blows in from the west. The two breezes meet in the middle of the peninsula, forcing the air to rise there and form a line of clouds over the spine of the peninsula. When night comes, the air cools and descends and at the same time a surface inversion (where air temperature increases with height) forms over the gulf. The densities in this stable layer are different above and below the inversion. The air descending from the peninsula to the east goes underneath the inversion layer and this generates a series of waves or rolling cylinders which travel across the gulf. These cylinders of air roll along the underside of the inversion layer, so that the air rises at the front of the wave and sinks at the rear. In the early morning, the air is saturated enough so that the rising air in the front produces a cloud, which forms the leading
