*🛡️Tropical Rain Destabilises Oceans Only When Light*


*💎Key Findings*
♟️Scientists earlier believed rain makes the ocean’s surface more buoyant (due to freshwater being lighter)
♟️New study (Univ. of Washington, July 2025) finds light rain destabilises the ocean, but heavy rain stabilises it

*💎Mechanism*
♟️Rain in tropics often comes with cold pools (cold, dry air + clouds)
♟️These cool the surface, block sunlight & transfer heat to air
♟️Thus, heavier rain makes surface cooler and more stable
♟️Light rain (0.2–4 mm/hr) increases mixing, while heavy rain = negative buoyancy flux (surface stays more stable)

*💎Additional Observations*
♟️Rainfall at night destabilises oceans more than during the day
♟️Researchers identified:
*⚜️Cold Rain Zone* (W. Pacific & Indian Ocean): High heat loss
*⚜️Hot Rain Zone* (Central Pacific): Less heat loss

*💎Impact on Climate*
♟️Ocean mixing affects carbon, heat, nutrient transport
♟️Rainfall dynamics influence weather and climate models
♟️Study highlights risk of prediction errors due to simplistic assumptions.

*🛡️Directive Principles Of State policy DPSP*

♟️The constitution of India aims to establish not only political democracy but also socioeconomic justice to the people to establish a welfare state.

♟️These provisions are given in Part IV of Indian Constitution.

♟️Directive Principles of state policy are in the form of instructions to the governments at the centre as well as states.

♟️Though these principles are non justiciable, they are fundamental in the governance of the country.

♟️The idea of the Directive Principles of State Policy has been taken from the
Irish Republic .

♟️The Directive Principles of State policy were incorporated in our constitution in order to provide economic justice and to avoid concentration of wealth in the hands of few people.

♟️The constitution covers from Article 36 to 51 as Directive Principles of State
Policy.

♟️They are unique blend of socialistic, liberal, democratic and Gandhian Principles.

♟️They describe as the ‘conscience of the constitution’.

♟️In the “State of Tamil Nadu etc. Vs L.Abu Kavur Bai” case in 1984 , the Supreme court held that although directive principles of State Policy are not enforceable, yet the court should not avoid them.

Dawki Or Umngot River Meghalaya
Popularly known as Dawki river, the Umngot river in Meghalaya is undisputedly the cleanest river in Asia with its crystal clear water. It originates from the Eastern Shillong Peak, which is located 1,800 m above sea level.

The river is in the village of Mawlynnong ("God's Own Garden") in Meghalaya, close to India’s border with Bangladesh, which is touted as Asia’s Cleanest Village.

Alongside cleanliness, the village has also achieved a rare feat — a 100% literacy rate.

It acts as a natural divide between Jaintia and Khasi hills, before finally flowing into Bangladesh.
