What are the Six Major Climate Regions? By Aurelio Locsin; Updated May 10, Though the weather of an area can change daily, when seen in longer periods, a general pattern of climate emerges. For example, though it may rain on some days in the tropics and on others in the desert, rainfall is greater and more constant in the former than the latter.
The modified Koppen system uses letters to denote the six major climate regions and their 24 sub-classifications.
These regions are based on average monthly temperature and precipitation values. Whilst it does not take full account of factors such as cloudiness, solar radiation, wind or even extremes in temperature, it still remains a useful system.
The Koppen World Climate Classification Map shows that not only is climate geographically diverse at the broad scale, defined by the latitude within which a region lies, there is considerable diversity of climate within these broad scale regions. In Europe, the Climates along the Mediterranean and towards the East are much warmer and brighter than those towards the North and West.
The Indian subcontinent also shows considerable diversity from the West to East from the North to South ranging from desert to equatorial. See Climate Zones Map India.
Even a small island of Srilanka has three distinct climatic zones. Within the same climatic zone, some locations may have contrasting or variable climatic conditions. These may be caused by the following factors: Latitude Temperature range increases with distance from the equator.
Also, temperatures decrease as you move away from the equator. This is because the suns rays are dispersed over a larger area of land as you move away from the equator.
This is due to the curved surface of the earth. In addition Polar Regions are colder because the suns rays have further to travel compared to place on the equator.
Altitude Temperatures decrease with height. The air is less dense and cannot hold heat as easily. Winds If winds are warm - they have been blown from a hot area - they will raise temperatures.
If winds have been blown from cold areas they will lower temperatures. Distance from the sea Land heats and cools faster than the sea. Therefore coastal areas have a lower temperature range than those areas inland. On the coast winters are mild and summers are cool.
In inland areas temperatures are high in the summer and cold in the winter. Aspect Slopes facing the sun are warmer than those that are not. Thus south facing slopes in the northern hemisphere are usually warm whereas slopes facing north in the southern hemisphere are warmest.The classical period is 30 years, as defined by the World Meteorological Organization (WMO).
These quantities are most often surface variables such as temperature, precipitation, and wind. Climate in a wider sense is the state, including a statistical description, of the climate system.
Major World Crop Areas and Climate Profiles (MWCACP) The Major World Crop Areas and Climatic Profiles has been digitized into PDF. The full document is available for download or an interactive table of contents iis available to view individual pages. World distribution of major climatic types The following discussion of the climates of the world is based on groupings of Köppen’s climatic types.
It should be noted that the highland climate (H) is also included here. Climate Classification and Climatic Regions of the World Climate Classification The Köppen Climate Classification System is the most widely used system for classifying the world's climates.
Major Climatic Regions of the world. This climatic region is situated in the interior of the big continents between the Taiga and the mid-latitude deserts.
Summers are short and warm. Köppen divided the Earth's surface into climatic regions that generally coincided with world patterns of vegetation and soils.
The Köppen system recognizes five major climate types based on the annual and monthly averages of temperature and precipitation.
