03 June 2026

• The India Meteorological Department (IMD) has revised the likely onset date of the Southwest Monsoon over Kerala to 4 June, later than its earlier forecast of 26 May (±4 days).
• The monsoon system advanced over parts of the Arabian Sea and Bay of Bengal but stalled before reaching the Kerala mainland.
• The delay comes amid concerns of a developing El Niño and IMD’s forecast of below-normal seasonal rainfall (90% of Long Period Average – LPA).

Key Points

• Kerala marks the official onset of the Southwest Monsoon over mainland India.
• IMD declares monsoon onset when:
  • At least 60% of 14 designated stations receive 2.5 mm or more rainfall for two consecutive days.
  • Westerly winds extend up to 600 hPa level (~4.5 km altitude).
  • Outgoing Long-wave Radiation (OLR) falls below 200 W/m², indicating deep cloud formation and convection.
  • The Northern Limit of Monsoon (NLM) indicates the furthest advance of monsoon winds.
  • Southwest Monsoon contributes nearly 75% of India’s annual rainfall and is crucial for Kharif agriculture.

Static Linkages

• Monsoon originates due to differential heating of land and sea and the northward shift of the Inter-Tropical Convergence Zone (ITCZ).
• Somali Jet transports moisture-laden winds from the Arabian Sea towards India.
• Western Ghats cause heavy orographic rainfall along the west coast.
• Major factors influencing monsoon: ENSO (El
• Niño-Southern Oscillation), Indian Ocean Dipole (IOD), Madden-Julian Oscillation (MJO), and Jet Streams.

Critical Analysis

Significance

• Determines timing of Kharif crop sowing.
• Influences water availability, hydropower generation, and food prices.
• Supports flood and drought preparedness.

Challenges

• Increasing monsoon variability due to climate change.
• High dependence of rainfed agriculture on timely rainfall.
• Forecast uncertainties caused by ocean atmosphere interactions.

Way Forward

• Strengthen weather forecasting and early warning systems.
• Expand agro-meteorological advisory services.
• Promote climate-resilient agricultural practices.
• Improve water-resource and reservoir management.
• Enhance research on monsoon dynamics and climate variability

• AIIMS Delhi researchers, in an ICMR-funded study published in EMBO Molecular Medicine, Midentified the biological pathway through which PM2.5 and PM10 affect foetal development.
• The study found that particulate matter can cross the placental barrier, trigger inflammation, suppress IGFBP3 (Insulin-like
• Growth Factor Binding Protein-3), and impair foetal growth.
• Research was conducted using rodent models and data from 994 pregnant women from Delhi and Deoghar (Jharkhand).

Key Findings

• PM2.5 and PM10 cross the placental barrier and reach the foetus.
• Cause:

  • Epigenetic changes (altered gene expression)
• Suppression of IGFBP3 leads to:
  • Restricted foetal growth
  • Low birth weight
  • Placental dysfunction
• Higher pollution exposure associated with:
  • Increased risk of preeclampsia
  • Adverse pregnancy outcomes
• Animal studies showed:
  • Smaller placentas

THE ‘HARVEST’ CHINA SEEKS IS ONE INDIA CANNOT AFFORD

Context of the News

• India and China have discussed exploring an “Early Harvest” in boundary delimitation during recent Special Representatives (SR) talks.
• China has proposed moving ahead with settlement in sectors where conditions are considered “ripe”, particularly the Sikkim sector.
• Concerns exist that a sector-wise settlement may weaken India’s position of pursuing a comprehensive package settlement of the entire boundary dispute.

Key Points

• 2005 Agreement on Political Parameters and Guiding Principles remains the basis for boundary negotiations.
• The agreement envisages a package settlement covering all sectors of the India-China boundary.
• India-China boundary is generally divided into:
  • Western Sector (Ladakh)
  • Middle Sector (Himachal Pradesh Uttarakhand)
  • Sikkim Sector
  • Eastern Sector (Arunachal Pradesh)
• Doklam Plateau remains strategically important due to its proximity to the Siliguri Corridor.
• China claims the India-Bhutan-China trijunction lies at Mount Gipmochi, while India and Bhutan support Batang La.
• China has increased border infrastructure and village construction near disputed areas.

Static Points to Remember

• Delimitation: Boundary definition on maps/documents.
• Demarcation: Physical marking of boundary on
  the ground.
• Watershed Principle is an important principle in mountain boundary determination.
• Siliguri Corridor (Chicken’s Neck) connects mainland India with the North-Eastern States.
• Nathu La and Cho La clashes (1967) occurred in the Sikkim sector.
• India and Bhutan maintain close strategic cooperation on border security issues.

Why It Matters for India?

Concerns

• May dilute the package settlement approach.
