Mysterious ‘gravity waves’ seen rippling out over our atmosphere Spectacular rippling waves spread out in the atmosphere above Australia last week - showing off a little-known phenomenon: gravity waves. ‘Gravity waves’ are very different to gravitational waves, the ripples from distant collisions in space captured by detectors on Earth - and refer to waves in our atmosphere. They’re often caused by collisions between air masses of different temperatures, creating ‘ripples’ which can be seen by satellites. Weather expert Andrew Miskelly said, ‘More atmospheric gravity waves. Triggered, in this case, by outflow from isolated thunderstorms over eastern NSW this afternoon.’ Adam Morgan of the Australian Bureau of Meteorology told ABC, ‘There was a big thunderstorm over the north-west of WA and the disturbance in this case was the cold air falling out of the thunderstorm and into the warmer air near the surface. ‘The difference in density there causes the disturbance and then the gravity wave can travel out as the cold air spreads out. ‘The disturbance will exist until everything rebalances itself, that's why they can travel a long way.’ The waves are known as ‘gravity waves’ because they are rebalanced by gravity, Science Alert reports. ;) there are two takes in this vid: take 1 : Atmospheric gravity waves over the Coral Sea this morning. take 2 : More atmospheric gravity waves. Triggered, in this case, by outflow from isolated thunderstorms over eastern NSW this afternoon. ... https://www.youtube.com/watch?v=6TX6SCP3EWI
