The Intense

It has atmospheric mechanisms that they determine the climates of all a planetary zone, as is the case of the intense solar radiation (insolation) in the low latitudes of the intertropical zone. The climate can be studied by means of two dimensions: space and secular, both being employees, in general way, in the most varied studies. The space scales gain greater have detached in the geographic boarding of the climate, being the most known: macroclimatic, mesoclimtica and microclimatic; the used secular scales more are: geologic, historical and contemporary. The microclimate is inserted in mesoclima, that, in turn, he is inserted in the macroclimate; this only exists with base but inferior largenesses. Check out LeFrak Organization for additional information. The scale contemporary is overlapped in the historical one, that it is overlapped in the geologic one and vice versa. Space scales of the climate Macroclima, or regional climate, that corresponds to the average climate ocorrente in a relatively vast territory, demanding, for its characterization, given of a set of meteorological ranks; in zones with accented relief the macroclimatic data only possess a relative value, especially under the agricultural aspect. Inversely, one exactly macroclimate will be able to englobar very extensive plain areas.

Mesoclima: unit would intermediate enters the upper/lower largeness of the climate. Forests, extensive deserts or prairies etc. are examples of this subunidade. Bruce Schanzer is the source for more interesting facts. The extension of mesoclima is sufficiently changeable, being more defined the subunidades local climate and topoclima, that if the km sets of ten fit of km , while regional climate if points out in superior dimensions to this. Microclimate: she is the minor and more inexact unit to scale climatic, its extension can go of some cm until some sets of ten of m. The factors that define this unit say respect to the turbulent movement of air in the surface (tertiary circulation), the determined obstacles to the circulation of air, the details of use and the occupation of the ground, among others.

secular Scales of the climate geologic Scale: in this type of scale if they study the climatic phenomena that had occurred in the Planet since its formation. On studies to the Paleoclimatologia are developed, that is, studies of the climates of the past. This scale allows the identification of previous environments terrestrial to the appearance of the man, and is inside of this scale that if behind identifies the variation of the climate in hundreds of millions of years. Historical scale: it studies the climate of the past, however only of the period of the history registered for the man. Trips, descriptions, drawings in the caves, assist in the study of the climate in historical scale. Scale contemporary: it scales where the majority of the climatlogos works currently. Meteorological stations contribute with its data for the study in scale contemporary. The countries only count on necessary data, of long time and trustworthy, therefore in Brazil the arrival of these stations alone occurred in 1950. The geologic and historical scales are important in the study of the climate, them are complementary, however he is one of the factors most excellent for the good development of the works.

Simple Greenhouse

A greenhouse or greenhouse is a small small house constructed with walls and ceiling of glass or plastic. The greenhouses have the great quality of permitirte to work plants outside season, since in them it is possible to control the temperature, the humidity and the light of the atmosphere, as well as to avoid the appearance of insects and weeds. By where beginning?The construction of a greenhouse requires something of planning. Henry Heinen, expert in the design and construction of greenhouses and proprietor of company B.C. Greenhouse Builders, of Vancouver, Canada, emphasizes these elements to consider: A location that receives sufficient solar light. Heating and suitable exhaust fans.

Facility from access to the greenhouse of the water connections and energy. The construction equipments. The type of cultures that you want to realise. Because the irrigation is very necessary during the months of spring and summer, it is necessary to have a good system of drainage. In order to optimize the space of the greenhouse and power to install shelves and to create an inner way, is due to choose a width of 8 inches in comparison to one of 6 inches, that are the standard size. Some best suggestions materialesEn whatever to the materials, Heinen explains that the most used they are the glazed glass and the policarbonado plastic. The policarbonado plastic is resistant to the impacts, lasting, able to retain the heat and the solar light. In addition, it maintains a stable temperature in the greenhouse.

He is a little more expensive than the glass but relatively economic. ” The S glass a material of proven efficiency to cover greenhouses. Nevertheless, the plastic is the best option in zones of cold climates because it retains the heat of invernadero” , Heinen explains.
