The seasonal variations together with annual variation in precipitation (includes both rain and snow) account for the formation of major biomes such as desert, rain forest and tundra. Many classification schemes for biomes exist.

Cornell University ecologist Robert H. Whittaker defined biomes by their vegetation type, and then devised a simple climate diagram on which he plotted the approximate boundaries of his biomes with respect to average temperature and precipitation. When plotted on Whittakers diagram, most locations on Earth fall within a triangular area, whose three corners represent warm moist, warm dry, and cool dry climates. Cold regions with high rainfall are rare, because water does not evaporate rapidly at low temperatures and because the atmosphere in cold regions holds little water vapour. At tropical and subtropical latitudes, where average temperatures range between ${20}^0$C and ${30}^0$C, vegetation ranges from rainforest, which is wet throughout the year and generally receives more than 250 cm of rain annually, to desert, which generally receives less than 50 cm of rain. intermediate climates support seasonal forests (150-250 cm rainfall), in which some or all trees lose their leaves during the dry season, or scrub and savannas (50-150 cm rainfall).
