Biome (Minecraft Guide)

Biomes are regions of the Minecraft Overworld with different geographical features like grass colour, heights and flora. In the code biomes will have different temperature values which tells the game whether it should rain or snow in the biome. The values are <0.15 for snow, 0.15 - 0.95 for rain and >1.0 for nothing.

Biomes are set into 5 different catagories they are snow covered, cold, medium, dry and neutral. In the 1.7 biome update they were given these codes so that biomes with big climate differences dont generate side by side.
