Alright, so Harmattan, made from Wind and Fire chakras, is basically hot and dry winds with some dust that can be harmful. It carries a bunch of dust along with the winds, so basically, it resembles sand storms in large quantities because it can limit visibility and even block the sun for several days because of how long these aerosol can be suspended. (pretty cool o^o)
Like normal wind, it can cut/slice through thigns and has winds' sharp features. It is unique because of how dry it is, so dry that it can absorb the water in pine trees and break them (because pine trees hold a lot of water) and it can reduce humidity to 15% that can result in spontaneous health issues .One can spew it from himself, or from the environment and manipulate Harmattan through that method. Harmattan is used by combining wind and fire chakra together to create harmattan chakra.
Exposed with harmattan, it can peel off/scotch the first la yer of the skin; dehydration. It looks like normal wind, but it is way more, making it really dangerous.
