Question

what factors affect the weather in a deciduous forest biome, why does the deciduous forest recieve 40 inches of rain a year,

what type of unusual weather occurs there, what are the prevailing winds, and how does the latitude and nearness of large bodies of water affect the region?

Thank you!

Answer 1

Turn your thinking around.  The deciduous forest does not affect the weather.  The weather was there first.  It is what allowed the deciduous forest to succeed over other biomes.
