Rain-bearing low cloud cover decreased significantly in last 50 years: study (downtoearth)

There was a decrease in low cloud cover over most regions in India between 1961 and 201, says a study published in the Indian Meteorological Department journal Mausam.

The annual mean low cloud cover, which is responsible for most of the rainfall, shows significant decreasing trend of - 0.45 per cent per decade. The decline is particularly evident in monsoon season, with the cloud cover reducing by 1.22 per cent per decade. Monsoon is responsible for 70 per cent of India’s rainfall and snowfall.

The study also shows a decline in the number of rainy days in the monsoon season at a rate of 0.23 days every decade, which means that India has lost approximately one rainy day in the last 50 years. This is going by the IMD definition of a rainy day: when total precipitation is 2.5 mm or more.

The paper argues that the trend is a cause of “worry” and finds that while the number of rainy days are reducing, the total amount of rainfall does not show much change. This indicates shorter, heavier bursts of rain, which affects crops and result in runoffs, thereby not helping in groundwater recharge.

Water is essential for life on the earth. Precipitation from the skies is the only source for it. India and the rest of Asia are dependent on the monsoons for rains. While the South West Monsoon is the main source for India as a whole, Tamil Nadu and coastal areas of South Andhra Pradesh get the benefit of the North East Monsoon, which is just a less dependable beat on the reversal of the South West Monsoon winds.

Supreme Court orally indicates that the government should not deport Rohingya “now” as the Centre prevails over it to not record any such views in its formal order, citing “international ramifications”.

The Supreme Court on Friday came close to ordering the government not to deport the Rohingya.

It finally settled on merely observing that a balance should be struck between humanitarian concern for the community and the country's national security and economic interests.

The court was hearing a bunch of petitions, one filed by persons within the Rohingya community, against a proposed move to deport over 40,000 Rohingya refugees. A three-judge Bench, led by Chief Justice of India Dipak Misra, began by orally indicating that the government should not deport Rohingya “now”, but the government prevailed on the court to not pass any formal order, citing “international ramifications”. With this, the status quo continues even though the court gave the community liberty to approach it in …
