I doubt the bows are going to fall apart the moment they get into a more humid climate. It'll make the drying period required to make them more difficult, yes. But the Mongols were not a desert people.
There are actually rain and snow at times in Mongolia. Which climate is significantly harsher than Europe. Also, the Mongols seemed to handle China and the areas around the Caspian/Black Sea well enough.
I can see them wearing out faster and needing replacements eventually, but it is a solvable problem.
