A morning glory cloud seen near Burketown has made the prestigious 2020 Bureau of Meteorology calendar.
Mike Zupanc's spectacular photo called "On Cloud Nine" will grace the month of June.
Mr Zupanc comes from Ipswich and flies gilders as well as being a fine photographer.
"Flying was something I'd always wanted to do, so I just went out and did it. A bit like photography, I just thought "what the heck?"' Mr Zupanc said.
While you'd normally find him photographing the local sports scene in Ipswich, Queensland, soaring the morning glory clouds that form near Burketown was always on his bucket list.
"As that cloud moves along it generates a big area of rising air in front of it, so once you're up in the air you can turn the engine off and just ride the waves of the cloud-a bit like a surfer surfing an ocean wave," he said.
"Soaring the morning glory cloud is is an incredible feeling and I'm already making plans to do it again."
Accordingt to BoM, the morning glory is a type of roll cloud which can be many hundreds of kilometres long.
They're generally rare, however they occur reasonably consistently across the Gulf of Carpentaria from September to November, with several normally forming during this period.
The wave-like cloud is usually formed, in the right conditions, by the interaction between sea breezes on both sides of Cape York Peninsula, which results in a line of cloud.
As night falls, the air over land cools and descends while an inversion (a stable layer of air where temperature increases with height) forms over the water in the gulf.
The descending air from the peninsula slips under the inversion layer and generates a series of waves which move across the gulf. At the head of each wave, water vapour in the rising air condenses to form cloud, while at the back it evaporates as it descends-forming the roll cloud.
