Satellite images have captured a usually invisible phenomenon known as atmospheric gravity waves pulsing through clouds off Western Australia’s north-west.
Bureau of Meteorology (BOM) senior meteorologist Adam Morgan said atmospheric gravity waves were basically ripples in the sky.
“When you think of waves in the ocean, they’re a type of gravity wave,” he said.
“When you throw a rock in a pond and you see the ripples flowing out, they’re gravity waves as well.
“Essentially gravity waves are disturbances in any sort of fluid, so we see them often in water, but the atmosphere is a fluid as well — so any sort of disturbances in there can generate waves.”
