How Intensities work on different weather conditions?

By Woofr, in Anima Rules Questions

Hello! I would like some enlightenment with hot and cold rules.

I know that based on the intensities, I can calculate the damage of a certain attack (like a psychic power, dominion, or spell) — but when it comes to a weather effect, what is the effect in the characters?

1 - If a character is in a very cold place without proper protection (the arctic, for example) and the place has, say, 10 intensities, the amount of damage would be 50 (Table 75: Cold Intensities). Would this damage exposure be dealt on each turn? Every minute? Every hour?

2 - If a character uses a piece of armor that gives some protection against cold, would it be possible to deduct points from that armor type (AT) from the intensities of the cold environment?

If there's a book where I could find this information, I would really appreciate a heads-up. I purchased Anima last year and i'm preparing to use it with my players now, but the information is very scattered and it is sometimes is hard to find.
