I get up from my meditative state, infuriated that you would disturb me like that.
Why would you do that senpai!? D:
But anyway, ahem...
Wind is one of the five basic elements in the Narutoverse. It can be generally described as sharp and thin, which is how we should project our chakra when trying to make Wind-based chakra. It is weak against fire as it can act as an oxygenic fuel source and make it burn more, but you can overcome fire using wind as well, since too much would make it dispel into nothing. Wind is also strong against lightning, since it acts as a natural insulator of electricity, thus making it useless. It can also be of a great aide to water techniques since it can push them and make the water have a much greater force than what it would usually have. Wind doesn't have to be used just for cutting and slicing as we would describe the chakra though, as it can also be used for pushing objects, such as the Hurricane Fists technique.
In the real world though, wind can be used differently. Wind can be used for generating power through the use of wind turbines loctaed on wind farms. It can also be used for carrying anything, such as scent, and other gases which can also be used as technically for fighting with wind.
How's that?
