hello community flight simulator

I am working on a flight simulator as realistic as possible but I do not know how to make the wind and rain or any other climatological condition affect the aircraft I would like your help please

 

Very welcome to this forum. I'm a user and I'm also making a flight simulator as realistic as possible. And probably there are other 3 more. The question is so big that I need to resume and here is my way:

But to resume you must think like in real life. The aircraft can be move buy PhysX forces and is moving inside the local wind. So you need to create the local wind first and you need to put a PhysX component into the airplane game object. You can use particles to give the impression of the rain. And there are a lot of tools in the asset store that can help you in the process.
