Monsoon a Unifying Bond:
Himalaya ranges in the North protects the subcontinent from extremely cold polar winds. This enables even northern India to have uniformly high temperature for their latitudes. This high temperature creates low pressure belt over the Indian regions. This helps the south-east trade winds to change direction to south-west after crossing equator and brings South-west monsoon.
Despite climate contrast and variations in region to region, the monsoons provide a rhythmic cycle of seasons every year. It is around this seasonal rhythm that the Indian land scape, its animals and plant life, its entire agricultural calendar and its total life of Indian people and their festival revolve around.
Though, monsoon is characterized by their most uneven distribution of rainfall in the country, yet they are responsible for fringing highly moist marine air almost every part of the country atleast for few weeks whether it brings rain or not.
