Now think why

• Thiruvananthapuram has equable climate?
• Chennai has more rains only after the fury of monsoon is over in most parts of the country?
• Jodhpur has a hot desert type of climate?
• Leh has moderate precipitation almost throughout the year?
• while in Delhi and Jodhpur most of the rain is confined to nearly three months, in Thiruvananthapuram and Shillong it is almost nine months of the year?

In spite of these facts see carefully if there are strong evidences to conclude that the monsoons still provide a very strong framework lending overall climatic unity to the whole country.

• Thiruvananthapuram has equable climate because it is situated near sea which has a moderating effect on its climate.

• Chennai does not get rainfall from Southwest monsoons during June to september. It gets its share of rainfall from retreating monsoon and prevalent northwest trade winds that bring moisture from Bay of Bengal during October-November.

• Jodhpur is situated in Thar desert. This area gets very less rainfall. The sand is heated up quickly during day and increases the temperature. Therefore, Jodhpur has a hot desert type of climate.

• Leh has moderate precipitation almost throughout the year because it is situated on landlocked plateau and the place is dry due to low temperature.

• Delhi and Jodhpur get rainfall mostly from monsoon and some from western disturbances. Thiruvananthapuram receives rainfall from monsoon as well as from local factors as it is situated near sea. Shillong is surrounded by lofty mountains that do not allow the rain bringing winds from Bay of Bengal to escape. Therefore, while in Delhi and Jodhpur most of the rain is confined to nearly three months, in Thiruvananthapuram and Shillong it is almost nine months of the year.

In spite of the above facts, we can say that monsoon unifies India as one because monsoon brings rainfall to most of India from north to south in span of 2-3 months. All the festivals and agricultural practices revolve around the monsoon rains.
