The specific and uniform local climate of a small site or habitat brought about by hills, slopes, woodland, lakes, or other features of the landscape. These features modify the general climate of the region. The term also is applied to any climatic condition in a relatively small area, within a few meters or less above and below the Earth's surface and within canopies of vegetation. The microclimates of a region are strongly tied to the average moisture, temperature, and winds of the climate and to latitude, elevation, and season. Weather and climate are sometimes, in turn, influenced by microclimatic conditions, especially by variations in surface characteristics. Wet ground, for example, promotes evaporation and increases humidity. The drying of bare soil, on the other hand, creates a surface crust that inhibits ground moisture from diffusing upward, which promotes the persistence of dry atmosphere. Microclimates control evaporation from surfaces and influence precipitation and so are important to the hydrologic cycle (the circulation of the Earth's waters). The effect of soil types on microclimates is considerable. Also strongly influencing the microclimate is the ability of the soil to absorb and retain moisture, which depends on the composition of the soil and its use.
