Option 3 : 4 only

The correct answer is 4 only.

• The whole of India has a monsoon type of climate.
  • But the combination of elements of the weather, however, reveals many regional variations.
  • These variations represent the subtypes of the monsoon climate.
  • It is on this basis that the climatic regions can be identified.
  • A climatic region has a homogeneous climatic condition which is the result of a combination of factors.
  • Temperature and rainfall are two important elements which are considered to be decisive in all the schemes of climatic classification.

• Koeppen based his scheme of Climatic classification on monthly values of temperature and precipitation.
• Koeppen used letter symbols to denote climatic types.
• Each type is further sub-divided into sub-types on the basis of seasonal variations in the distributional pattern of rainfall and temperature.
  • He used S for semi-arid and W for arid and the following small letters to define sub-types:
    • f (sufficient precipitation),
    • m (rain forest despite a dry monsoon season),
    • w (dry season in winter),
    • h (dry and hot),
    • c (less than four months with a mean temperature over 10°C), and
    • g (Gangetic plain). Accordingly,
• India can be divided into eight climatic regions.
