As it was mentioned before:
A little bit more subtle and not so direct effects which involves or are affected by wind:
- Fire- in fire basins, candles or Mining Helmet
- "creatures" and Familiars- some elements like bookmarks in Flying book, tail of Emberwing, "dress" of Skullfrost.
- Some of the ship's routs are affected by storm's- it is not a visual effect, however, has an impact, like in The shattered Isles Quest
- footprints on the snow? they disappear after awhile as covered with snow again due to wind...?
- Things resembling wind: Knowledge elemental - looks also like whirlwind:) and going this way Eternal Winter spell
