✔✔Köppen climate classification, widely used, vegetation-based, empiricalclimate classificationsystem developed by German botanist-climatologist Wladimir Köppen. His aim was to devise formulas that would define climatic boundaries in such a way as to correspond to those of the vegetation zones (biomes) that were being mapped for the first time during his lifetime. Köppen published his first scheme in 1900 and a revised version in 1918. He continued to revise his system of classification until his death in 1940. Other climatologists have modified portions of Köppen’s procedure on the basis of their experience in various parts of the world.



✔✔Thornthwaite climate classification A system for describing climates devised in 1931 and revised in 1948 by the American climatologist Charles WarrenThornthwaite (1889–1963) which divides climates into groups according to the vegetation characteristic of them, the vegetation being determined by precipitation effectiveness (P/E, where P is the total monthly precipitation and E is the total monthly evaporation). The sum of the monthly P/E values gives the P/E index, which is used to define five humidity provinces, with associated vegetation. A P/E index of more than 127 (wet) indicates rain forest; 64–127 (humid) indicates forest; 32–63 (subhumid) indicates grassland; 16–31 (semi-arid) indicates steppe; less than 16 (arid) indicates desert. In 1948 the system was modified to incorporate a moisture index, which relates the water demand by plants to the available precipitation, by means of an index of potential evapotranspiration (PE), calculated from measurements of air temperature and day length. In arid regions the moisture index is negative because precipitation is less than the PE. The system also uses an index of thermal efficiency, with accumulated monthly temperatures ranging from 0, giving a frost climate, to more than 127, giving a tropical climate. 

Answer 2

Compare and contrast thornthwaite's and koppen's classification of climates.

Explanation:

• The Thornthwaite climatic classification was developed in the 1931 and modified in 1948, and divides the earth on the basis of the vegetation and precipitation effectiveness P/E ratio.

• Koppen defined the climates on the basis of the seasonal precipitation and temperature patterns into the five major types the tropical, temperate and continental, dry and polar.

• Thornthwaite used moisture, thermal efficiency and Aridity and the humidity indexes for ranking the climates and lie the koppens his schemes also empirical as well as quantitative.

• Thonwaite made the addition of 32 more climatic type that was three times greater then Koppen's type. Thus became very difficult for the geographers to represent on the map as compared to the simple classification made be Koppen.
