led street light cost depends on climate

Climate refugees climate is the general state of a multi-year period atmosphere on Earth, is the overall performance of the process of that period all kinds of weather. A variety of meteorological elements (temperature, precipitation, wind, etc.), statistics (mean, extreme value, probability, etc.) is expressed in the fundamental basis of the climate. Closely related to climate and human society in many countries has had a long record on climate phenomena. China’s Spring and Autumn Period sundial measuring sun’s shadow to determine the season, Qin and Han dynasties, there are twenty-four solar terms and 72 designate the complete record. Climate word from ancient Greek, meaning to tilt refers to the heating and cooling of the climate with the extent of the tilt of the sun’s rays.
As a very famous series of LED Lighting Productsled street light cost depends on a lot of facts. But now, some people said, led street light cost depends on climate. As we all know, led streetlight cost is very low compared with the saving from energy.
Due to the different physical processes underlying surface in the different nature of the differences in the distribution of solar radiation in the Earth’s surface and oceans, land, mountains, forests reach the surface of the solar radiation climate in addition to a temperature generally in line with the latitudinal distribution characteristics, but also has obvious regional characteristics. Horizontal scale size, the climate can be divided into the climate, the climate and microclimate. The climate of global and regional climate, such as: the tropical rain forest climate, Mediterranean climate, polar climate, plateau climate; in climate is the climate of the smaller natural areas, such as: forest climate, urban climate, mountain climate, and lakes, climate, etc.; climate is a smaller range of climate, such as: climate affixed to the gas and small-scale special topography (such as a mountain or a valley).
Position in latitude, land and sea distribution, under the influence of atmospheric circulation, topography, ocean currents and other factors, the world’s climate is broadly divided into the following types:
Tropical rain forest climate: the annual high temperature and rainfall;
Savannah climate: high temperatures all year round, divided into dry and wet seasons;
Tropical desert climate: hot dry throughout the year;
Climate distribution Figure tropical monsoon climate: annual high temperature, dry and wet seasons of the points.
Subtropical monsoon climate and humid subtropical climate: summer hot and rainy in winter low temperature drier;
Mediterranean climate: mild winters and rainy, hot summers and drier;
Temperate maritime climate: warm in winter and cool in summer, the annual temperature is small, evenly distributed annual rainfall season;
Temperate continental climate: little precipitation, the winter cold, hot summer, the temperature large;
Temperate monsoon climate: Hot and rainy summer, the winter is cold and dry;
Mountain climate: from the foothills to the vertical variation of the Peak;
Polar tundra climate: winter cold, summer is short and cool;
The climate of polar ice sheets: cold throughout the year.
