I want the area I am currently making to have a hot summer climate, but to also some years have a cold winter, including frost and some snow.
I understand that this may affect the fauna, but what are your opinions on the the justification? The area I have is modeled loosely on Southern France.
My thinking is that a southern directed wind can bring drastically lower temperatures, which cause the cooling down on the area and thus the colder winter? Sometimes the winds do not blow from the North, and thus a warmer winter. Would that be sufficient to explain it?
The temperature I am maiming for is about in the 24-30 degrees Celsius in the Summer and about 1 to -5 in Winter, to make the Winter more bitter and harsh.
