The long term average being 30 years. These weather variations are affected by the temperature, precipitation, and wind.
Climate determinants include latitude, altitude, proximity to mountains and oceans, proportion of land to water, thermohaline circulation of the ocean, ocean currents, density and type of vegetation present in an area, as well as the areas' water retention and rainfall.
Climate are classified into three groups. These are Bergeron and Spatial Synoptic, Koppen, and Thornthwaite.
This layer of soil is called the A horizon.
