World Climate Zones Maps

In this article we’ll learn about the various world climate zones maps as there is a huge diversity in the world in terms of Climate. The words climate and weather are many times used interchangeably in common parlance but in reality they are quite different. Whereas climate is the long-term pattern of weather in a particular area, weather on the other hand can change on a hour-to-hour, day-to-day, month-to-month or even year-to-year basis. The weather patterns of a region are usually tracked for at least 30 years time span.

The most elaborate and extensive climate classification system of world climate zones was given by Wladimir Koppen, who was a Botanist by profession.  Koppen’s main climate groups are based on what types of vegetation that grow in a given climate classification region. Along with this the system can also be used for the analysis of ecosystem conditions and to identify the main types of vegetation within climates. Hence because of the link between climate and the plant life of a given region, Koppen’s system is useful in predicting future changes in plant life within that region.

Major Components Of Climate – World Climate Zones Maps

  • Atmosphere : The movement of air and gasses radically influence the climate patterns of the world. These also include the man made factors.
  • Hydrosphere: The movement of ocean currents and  variations in temperature and salinity, occur at much slower rates than changes to the atmosphere.
  • Cryosphere: It is the icy part of our ecosystem. This is another generally consistent part of the climate system. Ice sheets and glaciers reflect sunlight, and the thermal conductivity of ice and permafrost profoundly influences temperature. It also regulates the Thermo-Haline circulation.
  • Biosphere: The biosphere, the sum total of living things on Earth, profoundly influences climate. Vegetation influences climate by helping determine how the Sun’s energy is used on Earth. The abundance of plants and the type of land cover (such as soil, sand, or asphalt) impacts evaporation and ambient temperature. By means of Photosynthesis, plants contribute to the regulation of flow of greenhouse gasses in the atmosphere. Forests and oceans serve as “carbon sinks” that have a cooling impact on climate. Living organisms alter the landscape, through both natural growth and created structures such as burrows, dams, and mounds. These altered landscapes can influence weather patterns such as wind, erosion, and even temperature.

  • Rainfall on windward slope, leeward side.

Conclusion – World Climate Zones Maps

On the whole there is a vast diversity in the World Climate Zones maps. This is due to a variety of reasons, the primary one being the inclination of Earth’s axis on the plane of the elliptic. The Sun’s rays are never uniformly distributed on the entire surface of the earth. Earth receives direct Sun rays in a band that stretches between the Tropic of Cancer and the Tropic of Capricorn. Thus the Sun rays are direct on the equator twice a year. Due to this there is a variation in climate all over the world. Other reasons for various climate zones are ocean currents, topography and variation in landmass.
