भारतीय मानसून विभिन्न जलवायु कारकों से प्रभावित एक जटिल परिघटना है। भारत में मानसून की तीव्रता और वितरण को निर्धारित करने में महासागरीय और वायुमंडलीय कारकों की भूमिका की आलोचनात्मक परीक्षा करें। / The Indian monsoon is a complex phenomenon influenced by various climatic factors. Critically examine the role of oceanic and atmospheric factors in determining the intensity and distribution of monsoon rainfall in India.

Introduction

Monsoon - the basic climatic factor governing India is complex in its working and consequences.

15 words

Main Body

Indian monsoon - oceanic and atmospheric factor:

Oceanic factor:

1Distance from the sea:
eg. As we move away from searainfall decreases (West to East)
2Formation of Somalian current & increases monsoon impact.
3Merging of oceanic cell with inter-tropical convergence cells → beginning of monsoon
4Removal of southern branch of Westerlies from India → onset of monsoon

Atmospheric factors:

(i) Phenomena of El Nino(less rainfall)
La-Nina(more rainfall)

eg. Triple Dip la-Nina in India (HLI 2022)

(ii) Formation of Indian Ocean Dipole

+Ivemore rainfall
-Iveless rainfall
(iii) Merging of oceanic cell with inter-tropical convergence cellsbeginning of monsoon

(iv) Climate change:

eg. Bichar droughts in do 12.

Other oceanic factor:

(i) Urban heat island effect

eg. Urban foods

(ii) Blocking of the rain-branch

eg. Western ghats blockheavy rain in Kerala (S.W monsoon)

Atmospheric factors:

(ii) Climate change:

eg. Bichar droughts in do 12

However, the impact of climate change has led to the alteration of entire climate pattern of India based on monsoon.

Diagram

Diagram showing oceanic factors (distance from sea, Somalian current formation, tropical convergence) and atmospheric factors (El Nino/La Nina phenomena, Indian Ocean Dipole, climate change) with arrows indicating their influence on monsoon patterns

  • Clearly separates oceanic and atmospheric factors
  • Uses specific phenomena (IOD, ENSO) with examples
  • Mentions recent events (Triple Dip La-Nina 2022, HLI 2022)
  • Shows understanding of pressure systems and ocean currents
  • Addresses both positive and negative impacts
