Will retire from politics if BJP’s allegation against me proved: Mithun Rai

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.

Mangaluru/Udupi: The Dakshina Kannada and Udupi-Chikmagalur Lok Sabha constituencies recorded a tentative voter turnout of 77.4% and 76.1% respectively until 6 pm on Friday. In the 2019 polls, Dakshina Kannada recorded 77.9%, while Udupi recorded a 75.8% voter turnout.

The DK Lok Sabha constituency recorded a poll percentage of 71.8% at 5 pm. Among the constituencies, Sullia recorded a maximum of 78.4%, followed by Belthangady at 75.6%, Puttur at 75.2%, Bantwal at 73.7%, Mangalore at 73.5%, Mangalore City North at 69.8%, and Mangalore City South at 61.8%.

Urban apathy continued, with Mangalore City South recording the lowest polling percentage.

Meanwhile, Banjarumale, a remote village in Belthangady taluk, recorded 100% polling with all 111 voters showing up two hours before polling ended at 6pm.

Another interior polling station at Elaneer in the same taluk recorded 82% polling at 4 pm. The booth has 471 voters. The district has a total of 18,18,127 voters, with 9,30,928 females, 8,87,122 men, and 77 transgender individuals.

A good number of people turned out to vote during the early hours. Voters are bearing the scorching sun while stepping out to exercise their franchise as heat wave is sweeping through the state. 

The polling process remained largely peaceful, with long queues observed at polling stations from 7 am onwards in several polling stations. However, technical glitches caused delays at a polling station in Karopady, and at St. Xavier School Bejai, where polling was reportedly delayed by nearly two hours.

Polling staff at a booth near the Mulki police station mistakenly marked the wrong finger with ink during voting. They reportedly applied ink to the index finger of the right hand. According to sources, at least 50 individuals had their index finger of the right hand inked. Deputy Commissioner Mullai Mulihan clarified, "The matter was promptly addressed by the sector office. This error affected 8-9 voters"

A total of 18.18 lakh voters in the Dakshina Kannada Lok Sabha constituency and 15.85 lakh in Udupi-Chikmagalur hold the power to determine the fate of candidates competing for their respective segments. The polling process is currently underway across 1,876 booths in Dakshina Kannada and 1,842 polling stations in the Udupi-Chikmagalur segment.

In Dakshina Kannada, a closely contested battle is anticipated between Captain Brijesh Chowta representing the BJP and Padmaraj R Poojary from the Congress. Meanwhile, in the Udupi-Chikmagalur constituency, Kota Shrinivas Poojary of the BJP and K Jayaprakash Hegde of the Congress are the prominent contenders.

Mangaluru International Airport (MIA) has taken a step towards enhancing aircraft safety and has planned to install a Precision Approach Lighting (PAL) category 1 system near Sri Kordabbu Daivasthana, Unile.

The groundbreaking ceremony was held on Friday. The project involves various works related to the PAL system and aims to be completed in 20 months.

The airport has undertaken this project in accordance with safety recommendations from the ministry of civil aviation and the civil aviation safety and security regulator. The PAL CAT 1 system will provide pilots with improved visibility of runway 24 and guidance during their final landing approach. The system will be installed 900m from the threshold of runway 24, as this end of the runway accounts for 90% of aircraft landings at the airport.

The PAL will be mounted on approximately 18 lattice structures, which is a unique feature of the project. The lights will be fixed to frangible T-shaped structures. The project will complement the installation of runway centerline lights, which has already been completed and is awaiting approval from the Directorate General of Civil Aviation for commissioning.
