Answer the following questions in about 30 words.

(i) Which two climatic variables are used by Koeppen for classification of the climate?


(ii) How is the “genetic” system of classification different from the “empirical one”?


(iii) Which types of climates have very low range of temperature?


(iv) What type of climatic conditions would prevail if the sun spots increase?


(i) Koeppen’s empirical system of classifying the climatic variations by establishing a link between climate and vegetation is based on these variables:

Mean annual and monthly temperature


Mean precipitation


(ii) The empirical system of classification employs the use of available data like temperatures and precipitation to classify the climatic types. However, the genetic classification tends to associate the types of climates with their underlying causes.


(iii) The Tropical Humid Climate, found between Tropic of Cancer and tropic of Capricorn, has a very low range of temperature.


(iv) Since sunspots tend to lower the temperature of sun’s surface, their increase would be associated with cooler and wetter climatic conditions.
