Climates of Tamriel
For instance, according to the authors it adds “high quality cloud textures”, “auroras that move across the night sky” and “new sun and sunglare”. It all looks quite pretty, especially if you enjoy travelling across Skyrim on horseback and doing some sightseeing. The mod also adds “506 new unique weather systems”. That’s a lot of weather systems indeed, and proof that a lot of work went into this fully-featured climate mod.
