A microclimate is a local atmospheric zone where the climate differs from the surrounding area. The order Cyatheales is a Taxonomic division of the Fern subclass Cyatheatae, which includes the tree ferns. In physical geography, a dell is a small Wooded Valley. Like "dale" the word "dell" is derived from the Old English language The Lost Gardens of Heligan, near Mevagissey in Cornwall, are one of the most popular Botanical gardens in the UK. Cornwall ( Kernow ˈkɛɹnɔʊ is the most southwesterly county of England, on the Peninsula that lies to the west of the River Tamar Climate encompasses the temperatures humidity rainfall atmospheric particle count and numerous other meteorogical factors in a given region over long periods of The term may refer to areas as small as a few square feet (for example a garden bed) or as large as many square miles (for example a valley). Microclimates exist, for example, near bodies of water which may cool the local atmosphere, or in heavily urban areas where brick, concrete, and asphalt absorb the sun's energy, heat up, and reradiate that heat to the ambient air: the resulting urban heat island is a kind of microclimate. prod concern = This definition copied to Wiktionary on 10/11/2008 month = October day = 12 year = 2008 time = 0047 timestamp = 20081012004724 An urban heat island ( UHI) is a metropolitan area which is significantly warmer than its surrounding rural areas
Another contributory factor to microclimate is the slope or aspect of an area. In Physical geography, aspect generally refers to the direction to which a Mountain slope faces South-facing slopes in the Northern Hemisphere and north-facing slopes in the Southern Hemisphere are exposed to more direct sunlight than opposite slopes and are therefore warmer for longer. Northern Hemisphere is the half of a Planet that is North of the Equator —the word hemisphere literally means 'half ball' Southern Hemisphere is the half of a Planet that is South of the Equator —the word hemisphere literally means 'half ball'
The area in a developed industrial park may vary greatly from a wooded park nearby, as natural flora in parks absorb light and heat in leaves, that a building roof or parking lot just radiates back into the air. In Botany, flora ( Plural: floras or florae has two meanings The first meaning flora of an area or of time period, refers to all Solar energy advocates argue that widespread use of solar collection can mitigate overheating of urban environments by absorbing sunlight and putting it to work instead of heating the local surface objects. Solar energy is the Light and radiant heat from the Sun that powers Earth 's Climate and Weather and sustains Life
A microclimate can offer an opportunity as a small growing region for crops that cannot thrive in the broader area; this concept is often used in permaculture practiced in northern temperate climates. A growing region is an area suited by Climate and soil conditions to the cultivation of a certain type of crop The word permaculture, coined by Australians Bill Mollison and David Holmgren during the 1970s is a Portmanteau of perma nent agri' Microclimates can be used to the advantage of gardeners who carefully choose and position their plants. Cities often raise the average temperature by zoning, and a sheltered position can reduce the severity of winter. Zoning is a term used in Urban planning for a system of land-use Regulation in various parts of the world including North America the United Kingdom Winter is one of the four Seasons of Temperate zones Calculated astronomically, it begins on the Solstice and ends on the Equinox Roof gardening, however, exposes plants to more extreme temperatures in both summer and winter
Microclimates can also refer to purpose made environments, such as those in a room or other enclosure. A roof garden is any Garden on the Roof of a Building. Humans have grown Plants atop structures since antiquity. Microclimates are commonly created and carefully maintained in museum display and storage environments. This can be done using passive methods, such as silica gel, or with active microclimate control devices. Silica gel is a granular porous form of Silica made synthetically from Sodium silicate.
