Notes:

India’s climate closely resembles the climate that of a tropical country although it’s northern part (north of tropic of cancer) is situated in the temperate belt. 

  • Indian subcontinent is separated from the rest of Asia by the lofty Himalayan ranges which block the cold air masses moving southwards from Central Asia. 
  • As a result, during winters, the northern half of India is warmer by 3°C to 8°C than other areas located on same latitudes. 
  • During summer, due to over the head position of the sun, the climate in the southern parts resemble equatorial dry climate. 
  • The north Indian plains are under the influence of hot dry wind called ‘loo’ blowing from the Thar, Baloch and Iranian Deserts, increasing the temperatures to a level comparable to that of the southern parts of the country. 
  • The climate in most of the regions is characterized by distinct wet and dry seasons.  
  • Some places like Thar desert, Ladakh have no wet season. Mean annual rainfall varies substantially from region to region.  
  • Mawsynram and Cherrapunji in Meghalaya receive around 1,000 cm of annual rainfall while at Jaisalmer the annual rainfall rarely exceeds 12 cm.
