Monsoon in India


Monsoons

The word Monsoon originated from the Arabic word “mawsim”, which means season. Monsoons refer to seasonal winds that are reversed from their directions according to the changing seasons and are hence known to be periodic. The monsoons tend to travel from sea to land in summers and from land to sea during winters, which gives rise to the concept of a double system of seasonal winds.

India receives Southwest monsoon winds during the summers and northeast monsoons are received during the winters. The former arises because of the formation of the intense low-pressure system over the Tibetan plateau and the latter arises because of high-pressure cells that are formed over the Siberian and Tibetan plateaus.

Southwest Monsoon

The southwest monsoon is caused because of intense low-pressure formation over Tibetan Plateau for intense heating during the summer season; there is a permanent form of high-pressure cell located in the South of the Indian Ocean. The winds of the Southwest monsoon bring heavy rainfall in most parts of the country.

Factors Influencing Onset of Southwest Monsoons

The factors which influence the onset of Southwest Monsoons include:

  1. Intense low pressure is formed over the Tibetan plateau.
  2. Permanent high-pressure cell in the south of the Indian Ocean.
  3. Subtropical jet stream
  4. African Easterly stream
  5. Inter-Tropical Convergence Zone (ITCZ)

Northeast Monsoon

The northeast monsoon is caused by high-pressure cells over the Tibetan and Siberian Plateaus. The NE monsoon winds bring rainfall to the southeast coast of the country which includes the Tamil Nadu coast as well as Seemandhra’s south coast.

The factors which are mostly responsible for the formation of NE monsoons include:

  1. Formation as well as strengths of high-pressure cells over Tibetan and also Siberian Plateaus during winters.
  2. Migration of Inter Tropical Convergence Zone to the south of India.
  3. High-pressure cells in the Southern Indian Ocean migrated to the west and then weakened.

  • Indian Monsoon is influenced by the presence of a great pressure region in East Madagascar roughly at  20°S over the Indian Ocean; influences the Indian Monsoon.
  • At the point when the land is warmed and water bodies get cooled, it makes low tension on the ground and high strain over the ocean as well as the other way around.
  • The shift of the place of the Inter-Tropical Assembly Zone in summer, over the Ganga plain (this is the tropical box typically situated around 5°N of the equator. It is otherwise called the monsoon.
  • The inordinate warming of the Tibetan level during summer brings about solid air flows which are vertical in bearing.
  • If the pressure contrasts were negative, it would mean underneath normal and late monsoon. A component associated with the SO is the El Nino phenomenon wherein a warm sea momentum streams past the Peruvian Coast.
  • The changes in pressure conditions are associated with El Nino. Thus, the phenomenon is alluded to as ENSO (El Nino Southern Oscillations).

The length of the rainstorm is between 100 and 120 days from early June to mid-September.  the typical precipitation expands out of nowhere and proceeds continually for a very long time. This is known as the ‘explosion’ Or  “burst” of the monsoon and can be recognized from the monsoon showers.
