This Rousing Air farming guide will show you the places where I farm Rousing Air in Dragonflight.
Awakened Air comes from combining 10 Rousing Air, so if you need Awakened Air, you have to farm Rousing Air.
Farming Unleashed Storms in Ohn'ahran Plains is the best source of Rousing Air, but you can only farm them when the "Wind Breaker" world quest is active.
The smaller neutral mobs won't drop any loot, so try not to pull them.
The Azure Span
Restless Winds and Restless Gales in The Azure Span is also great source of Rousing Air.
