Flights hit, 1,500 stranded fliers being evacuated from Chennai airport

New Delhi: India is likely to experience above-normal cumulative rainfall in the 2024 monsoon season with La Nina conditions likely to set in by August-September, the IMD has said on Monday.

However, normal cumulative rainfall does not guarantee uniform temporal and spatial distribution of rain across the country, with climate change further increasing the variability of the rain-bearing system.

Climate scientists say the number of rainy days is declining while heavy rain events (more rain over a short period) are increasing, leading to frequent droughts and floods.

Based on data between 1951-2023, India experienced above-normal rainfall in the monsoon season on nine occasions when La Nina followed an El Nino event, India Meteorological Department chief Mrutyunjay Mohapatra told a press conference here.

Positive Indian Ocean Dipole conditions are predicted during the monsoon season. Also, the snow cover in the Northern Hemisphere is low. These conditions are favourable for the Indian southwest monsoon, he said.

Moderate El Nino conditions are prevailing at present. It is predicted to turn neutral by the time monsoon season commences. Thereafter, models suggest, La Lina conditions may set in by August-September, Mohapatra said.

India received "below-average" cumulative rainfall -- 820 mm compared to the long-period average of 868.6 mm -- in 2023, an El Nino year. Before 2023, India recorded "normal" and "above-normal" rainfall in the monsoon season for four years in a row.

El Nino conditions -- periodic warming of surface waters in the central Pacific Ocean -- are associated with weaker monsoon winds and drier conditions in India.

Three large-scale climatic phenomena are considered for forecasting monsoon season rainfall.

The first is El Nino, the second is the Indian Ocean Dipole (IOD), which occurs due to differential warming of the western and eastern sides of the equatorial Indian Ocean, and the third is the snow cover over the northern Himalayas and the Eurasian landmass, which also has an impact on the Indian monsoon through the differential heating of the landmass.

The southwest monsoon delivers about 70 percent of India's annual rainfall, which is critical for the agriculture sector. Agriculture accounts for about 14 percent of the country's GDP.

The Supreme Court of India on Friday, April 26, rejected pleas seeking 100% cross-verification of votes cast using EVMs with a Voter Verifiable Paper Audit Trail (VVPAT) and said “blindly distrusting” any aspect of the system can breed unwarranted scepticism.

A bench of Justices Sanjiv Khanna and Dipankar Datta delivered two concurring verdicts. It dismissed all the pleas in the matter, including those seeking to go back to ballot papers in elections.

An EVM comprises three units – the ballot unit, the control unit and the VVPAT. All three are embedded with microcontrollers with a burnt memory from the manufacturer. Currently, VVPATs are used in five booths per assembly constituency.

EVM VVPAT case: Supreme Court issues two directives

1.    Justice Khanna directed the Election Commission of India to seal and store units used to load symbols for 45 days after the symbols have been loaded to electronic voting machines in strong rooms.

2.    The Supreme Court also allowed engineers of the EVM manufacturers to verify the microcontroller of the machines after the declaration of the results at the request of candidates who stood second and third. The top court said the request for the verification of the microcontroller can be made within seven days of the declaration of the results after payment of fees.

Option for candidates to seek verification of EVM programmes

•    Candidates who secure second and third position in the results can request for the verification of burnt memory semicontroller in 5% of the EVMs per assembly segment in a Parliamentary constituency. The written request to be made within seven days of the declaration of the results.

•    *On receiving such a written request, the EVMs shall be checked and verified by a team of engineers from the manufacturer of the EVMs.

•    Candidates should identify the EVMs to be checked by a serial number of the polling booth.

•    Candidates and their representatives can be present at the time of the verification.

•    After verification, the district electoral officer should notify the authenticity of the burnt memory.

•    Expenses for the verification process, as notified by the ECI, should be borne by the candidate making the request.
What did the Supreme Court say?

•    "If EVM is found tampered during verification, fees paid by the candidates will be refunded," the bench said.

•    "While maintaining a balanced perspective is crucial in evaluating systems or institutions, blindly distrusting any aspect of the system can breed unwarranted scepticism...," Justice Datta said.

Who filed the petitions?

NGO Association for Democratic Reforms, one of the petitioners, had sought to reverse the poll panel's 2017 decision to replace the transparent glass on VVPAT machines with an opaque glass through which a voter can see the slip only when the light is on for seven seconds.

The petitioners have also sought the court's direction to revert to the old system of ballot papers.

Electronics Corporation of India Ltd and Bharat Electronics Ltd have refused to disclose the names and contact details of the manufacturers and suppliers of various components of EVMs and VVPATs under the RTI Act citing "commercial confidence", according to RTI responses from the PSUs to an activist.

Activist Venkatesh Nayak had filed two identical Right To Information applications with the ECIL and BEL, seeking the details of the manufacturers and suppliers of various components used in the assembling of the electronic voting machines (EVMs) and voter-verifiable paper audit trail (VVPATs).

The VVPAT is an independent vote verification system which enables electors to see whether their votes have been cast correctly.

The ECIL and the BEL, public sector undertakings under the Ministry of Defence, manufacture EVMs and VVPATs for the Election Commission.

Nayak also sought a copy of the purchase orders for the components from both PSUs.

"Information sought is in commercial confidence. Hence details cannot be provided under Section 8(1)(d) of the RTI Act," BEL said in its response.

A similar response was sent by ECIL which said the details requested are related to a product which is being manufactured by ECIL, and third party in nature.

"Disclosing of details will affect the Competitive position of ECIL. Hence, Exemption is claimed under section 8(1) (d) of RTI ACT, 2005," it said.

In response to the purchase order copies, ECIL's central public information officer said the information is "voluminous" which would disproportionately divert the resources of the Public Authority.

"Further, the information will give away the design details of EVM components. The same may pose a danger to the machines produced. Hence, the exemption is claimed U/s 7(9) and under section 8(1)(d) of RTI Act, 2005," ECIL said.

Section 8(1)(d) of the RTI Act exempts from disclosure the information, including commercial confidence, trade secrets or intellectual property, the disclosure of which would harm the competitive position of a third party, unless the competent authority is satisfied that larger public interest warrants the disclosure of such information.

Section 7(9) of the Act says the information shall ordinarily be provided in the form in which it is sought unless it would disproportionately divert the resources of the public authority or would be detrimental to the safety or preservation of the record in question.

"I don't know whose interests they are trying to protect against the right to know of close to a billion-strong electorate. ECIL said that disclosure of the purchase orders will reveal the design details of the components and this may pose a danger to the machines produced. ECIL did not upload even a signed copy of its reply on the RTI Online Portal," Nayak said.

He said it is reasonable to infer that the two companies are not manufacturing every single item of the EVM-VVPAT combo or else the two companies would have replied that they are manufacturing all these components internally without any outsourcing being involved.

"But the electorate is expected to take everything about the voting machines based on what the ECI is claiming in its manuals and FAQs," Nayak said.
