Stalin to bring bill seeking exemption from NEET exam
 

A 19-year-old NEET aspirant died allegedly by suicide in Tamil Nadu’s Salem district on Sunday, prompting chief minister MK Stalin to say that legal battle against the national entrance exam was just beginning, and promised to bring a bill against it on Monday. The National Eligibility cum Entrance Test (NEET) 2021 for admission in undergraduate medical courses was conducted across 202 cities on Sunday, after the Supreme Court recently rejected a plea by a group of students to postpone the exam. The student from Salem, who was the son of a farm labourer, was found dead in his room hours before he was slated to attempt the exam for the third time, said a police official. Stalin assured students that the DMK government will pass a bill in the state assembly on Monday, seeking permanent exemption from NEET. “Let the injustice end,” he said in a statement, adding that: “Our legal battle against NEET is just beginning.” P9

‘Mortality rate rises with plasma therapy’
 
 

Even with doubtful efficacy, antibody-rich plasma from recovered Covid-19 patients continued to be used for the treatment of those suffering from the infection during the second wave of the pandemic, with people queuing up at plasma banks and looking for donors online. But a recent Canadian study published in the journal Nature has shown that not only did plasma therapy not help in Covid treatment, it increased the risk of severe adverse events, and the number of deaths was also higher among those who received the therapy. The study showed that the proportion of deaths on Day 30 was slightly higher in the people who received plasma therapy — 23% as compared to 20.5% in the control group. But the difference was not significant, according to the study. P9

A Jammu & Kashmir policeman was killed on Sunday after a suspected terrorist fired at him in Srinagar’s old city area, police said. Probationary sub-inspector (SI) Arshid Ahmad was shot at twice from behind in Khanyar area, police said. He was immediately rushed to Sheri Kashmir Institute of Medical Sciences (SKIMS) in Soura where he succumbed to injuries, they added. “Police officer Arshid Ashraf who was shot at by terrorists in Khanyar succumbs to his injuries,” Jammu and Kashmir Police said. Ahmad was a resident of Kupwara in north Kashmir and was posted at Khanyar police station. Peoples Democratic Party (PDP) chief Mehbooba Mufti and National Conference leader Omar Abdullah were among those who condemned the attack on Sunday. P7

Kharif crops under threat from rains
 
 

Moisture-propelling weather patterns across India have reactivated the monsoon system again, flooding several states and threatening key summer-sown or kharif crops, including onion, a widely consumed price-sensitive food item. A cyclonic circulation over the Bay of Bengal, dumping heavy rainfall in West Bengal, moisture drafts due to a low-pressure formation over northern states and a rainy trail across Gujarat, Rajasthan, Madhya Pradesh, Chhattisgarh and Odisha has flooded large parts of several states, endangering crops. Rice fields in many districts of the food bowl states of Punjab, Haryana and parts of Uttar Pradesh have gone underwater, growers said, while Delhi witnessed historic rains Saturday. The India Meteorological Department said there could be “damage to horticulture and standing crops in some areas due to inundation” in an alert on Saturday. P8

New Delhi : Delhi has recorded 33% excess rain since June 1, according to weather experts. But this did not happen because of a wholesome monsoon in the last three months but because of an abrupt spike in rain in July and September, and in the latter case, a week before monsoon is normally expected to start receding. Experts said this could be due to climate change.

According to India Meteorological Department (IMD) data, Delhi’s Safdarjung observatory recorded 47% rain deficiency in June, 140% excess in July, 13% deficiency in August, and 193% excess till September 11. This monsoon, the observatory, which provides representative data for the city, logged seven heavy rainfall days (precipitation of 64.4mm and above) — the most since 1901 — on July 19, 27, and 29, August 20, September 1, 2 and 11.

Weather forecasters said that this year, while there have been fewer rainy days, the intensity of the showers was more. August saw just six rainy days but September has seen eight already.

“Seven heavy rain days in Delhi (Safdarjung) this monsoon are the highest ever recorded, beating the earlier record of six heavy rain days in 1964,” said RK Jenamani, senior scientist at national weather forecasting centre, IMD

This skewed pattern of rain over Delhi is mainly because there were three phases of subdued monsoon in July and August.

Monsoon entered a ‘break’ or a ‘partial break’ phase between June 29 and July 11; it was very weak in the first two weeks of August also, leading to a significant rain deficit across the country. While it revived over northwest India on August 19, it weakened again from August 24 onwards and started reviving very gradually from August 29. These partial breaks were interspersed with only a few days of very heavy rain in Delhi, leading to traffic disruptions, urban flooding and impact on other utilities.

Not only were there fewer rainy days this year, Delhi also recorded intense spells of rain in only a few hours — an indicator of climate change. For example, between 5.30 am and 8.30 am on Saturday, Safdarjung station recorded 81.3mm rain while Palam recorded 98mm.

“The monsoon trough is in the vicinity of Delhi, there is also a low-pressure area over eastern parts of Rajasthan. Moisture laden winds are also penetrating up to mid-tropospheric levels (8000-10,000 feet), which is aiding the formation of convective clouds. This spell is likely to continue for the next 24 to 36 hours then reduce over Delhi and its neighbourhood,” said Mahesh Palawat, vice president, Skymet Weather, a private weather forecasting company.

He also talked about another low-pressure area forming over north Odisha, which is likely to intensify into a depression, triggering another spell of rain over central India, impacting the entire region from Odisha to southeast Rajasthan and Gujarat. “Standing crop is likely to be impacted. Pulses are particularly vulnerable to damage. However the heavy rain spell will fill reservoirs in Gujarat and Rajasthan where there was a very long dry spell in August, which will be useful for the Rabi crop,” Palawat said.

Undeniable role of climate crisis: Experts

Active monsoon conditions coupled with the climate crisis are leading to these intense spells of rain and several dry days. “Certainly, climate change has a role to play in the extreme rainfall we are seeing during a short duration of three to six hours as was the case in Delhi on Saturday morning. With air temperature increasing, the moisture-carrying capacity of the atmosphere has also increased. This mainly leads to the formation of convective clouds that bring thunderstorms, lightning, extremely heavy rain, etc.” Palawat explained.

He said that earlier, such convective clouds were commonly seen during the pre-monsoon season while during monsoon, altostratus clouds or thin sheets of clouds were commonly formed. “We don’t see them forming much anymore. Altostratus clouds used to bring continuous slow rain for 2-3 days during monsoon,” Palawat added.

M Rajeevan, former secretary, ministry of earth sciences, said there was a long phase of subdued rain in August due to global warming. “Rainfall was also subdued over southeast Asia. Models didn’t perform well and this deficit was not anticipated. But we have been underlining that longer dry periods with intense rain spells are becoming the norm. There is intense convective activity. Convective clouds can produce a lot of rain. Cities like Delhi should prepare for this kind of rainfall pattern,” Rajeevan said.

Negative Indian Ocean Dipole over the tropical Indian Ocean — a phenomenon where the western Indian Ocean becomes colder than the eastern one and is unfavourable for monsoon — prevailed throughout August, contributing to deficient rainfall, IMD had said earlier this month. There were also fewer typhoons in the west Pacific and so there was an absence of westward movement of their remnants into the Bay of Bengal. This led to fewer low-pressure systems forming over the Bay of Bengal.

Monsoon withdrawal to be delayed in 2021: Met

“There were some large-scale features that we are still trying to understand. August was an anomaly for many parts of South Asia,” added Rajeevan. IMD had also acknowledged last week that the multi-model ensemble forecasting system couldn’t pick up the deficit in August rain.

“Now there is heavy and widespread rain in many parts of the country because the monsoon is active and monsoon circulation is very strong. We can expect some episodes of heavy rain during such phases of monsoon. It’s also true that with climate change and more water vapour availability, severe localised convective activity takes place, bringing intense rain in a short duration similar to what you are seeing in Delhi,” explained R Krishnan, executive director, Centre for Climate Change Research.

“Usually in Delhi, August is the rainiest month, but our recordings show that in July and September we saw excess rain. In August, because of two long break phases, there was a deficit. In just 11 days, the rainfall recordings in Delhi have already reached record levels. This usually doesn’t happen. For instance, in the last two years in September there has been less than 100mm rainfall,” the official said.

Monsoon is normally expected to start withdrawing from northwest India on September 17, but is likely to be delayed this year, IMD officials added.

New Delhi : The city is likely to get mostly light spells of rain over the coming week, the India Meteorological Department (IMD) said in its Sunday forecast, as parts of Delhi received showers for the second straight day.

According to IMD, on Sunday, the Safdarjung Observatory, considered representative of Delhi’s weather, received 41.1mm of rain between 8.30am on Saturday and 8.30am on Sunday, and then 1.2 mm rain between 8.30am and 5.30pm.

“Light rain or thundershowers will continue till September 15-16. Another spell of moderate intensity rainfall is likely around September 16-17. This month will see rainfall on and off, with monsoon likely to withdraw late from northwest region including Delhi,” said a senior official, who didn’t wish to be named.

Delhi on Saturday received 81.3mm rain in just three hours, starting 5.30am, which broke a 46-year-old record, making it the wettest monsoon for the city since 1975. The city has received 1,136.8mm rain so far this monsoon. It last received more rain in 1975, when Delhi recorded 1155.6mm rain.

The all-time record, from 1933, stands at 1420.3 mm, according to IMD.

The unusual monsoon this year has set another record — after 1944, which had the rainiest September on record, this year’s September has so far reported the most rainfall. With a good part of the month still left, this year’s September could become the rainiest since 1901, the year when earliest rainfall data is available.In just 11 days, the city has recorded 380.2mm rainfall, according to data. In September 1944, the city received 417.3mm rain.

Unlike July and August that saw dry phases, September so far has not had any such spells, and the city has seen some rainfall on most days this month.

“The continuous rain spells are mainly on account of easterly winds and frequently forming low pressure systems in the Bay of Bengal, which travelling up to north and central India are bringing rainfall,” the official added.

According to scientists, Delhi has witnessed seven heavy rain events (64.4mm rainfall and above) this year, the highest ever. Normally, Delhi records just one or two such events in the entire season, between June 1 and September 30.

“This monsoon has already featured in the list of the top five wettest seasons. We might break more records but we will have to wait for the final rainfall data,” RK Jenamani, senior IMD scientist, told HT on Saturday.

Despite monsoon arriving in Delhi on July 13, making it the most-delayed in 19 years, the capital recorded 16 rainy days in the month, the maximum in the last four years.
