Hello once more everyone!

Okay, so this map is not the most natural I know but it just gives me so much possibility for my future books that I have to keep it. Now I was wondering how such a landscape would be affected by two huge long mountain chains. On the western part, you have the clouds that cannot get past through the first mountain chain unless they pour out their rain so we have a really humid area. In the center, the Wind from the desert land to the South are kept prisonner and sometimes they clash with colder winds from the north. So yeah, you have dry hot winds and cold winds clashing all the time and there is that long wide river going north as well. To the east, not much really. Oh! I forgot! Because of the two mountain chains, the in-between (still have to name it) has year-round short days. That mean it could certainly make the nights cold despite the hot winds from the South.
