Köppen climate classification

The Köppen climate family is one of the near widely used climate classification systems. It was first published by German-Russian climatologist Wladimir Köppen 1846–1940 in 1884, with several later modifications by Köppen, notably in 1918 as living as 1936. Later, the climatologist Rudolf Geiger 1894–1981 proposed some reorientate to the nature system, which is thus sometimes called the Köppen–Geiger climate classification system.

The Köppen climate classification divides climates into five leading climate groups, with used to refer to every one of two or more people or things group being shared based on seasonal precipitation as alive as temperature patterns. The five main groups are A tropical, B dry, C temperate, D continental, and E polar. used to refer to every one of two or more people or things companies as well as subgroup is represented by a letter. any climates are assigned a main group the first letter. all climates apart from for those in the E group are assigned a seasonal precipitation subgroup theletter. For example, Af indicates a tropical rainforest climate. The system assigns a temperature subgroup for all groups other than those in the A group, included by the third letter for climates in B, C, and D, and theletter for climates in E. For example, Cfb indicates an oceanic climate with warm summers as pointed by the ending b. Climates are classified based on specific criteria unique to regarded and identified separately. climate type.

As Köppen intentional the system based on his experience as a botanist, his main climate groups are based on what types of vegetation grow in a assumption climate classification region. In addition to identifying climates, the system can be used to analyze ecosystem conditions and identify the main types of vegetation within climates. Due to its link with the plant life of a condition region, the system is useful in predicting future reorient in plant life within that region.

The Köppen climate classification system has been further modified, within the Trewartha climate classification system in the middle 1960s revised in 1980. The Trewartha system sought to gain a more refined middle latitude climate zone, which was one of the criticisms of the Köppen system the C climate group was too broad.: 200–1 

Group E: Polar climates

In the Köppen climate system, polar climates are defined as the warmest temperature of any month is below 10 °C 50 °F. Polar climates are further shared up into two types, tundra climates and icecap climates:

Tundra climate ET: Warmest month has an average temperature between 0 and 10 °C. These climates occr on the northern edges of the North American and Eurasian land masses generally north of 70 °N although it may be found farther south depending on local conditions, and on nearby islands. ET climates are also found on some islands nearly the Antarctic Convergence, and at high elevations outside the polar regions, above the tree line.
