Chandrayaan-2 orbiter doing very well, no communication with lander: ISRO Chief

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 Delhi High Court rejected Chief Minister Arvind Kejriwal's plea challenging his arrest by the Enforcement Directorate (ED) and remand order passed by the trial court in connection with the excise policy case. The court delivered the verdict in the excise policy case on Tuesday.

In its order, the high court said the petition challenged the arrest and said it was in violation of Section 19 of the Prevention of Money Laundering Act, 2002 (PMLA). "The court clarifies that the plea is not for bail but for declaring the arrest illegal," Bar and Bench reported while citing the court order.

The high court said the material collected by the ED “reveals Arvind Kejriwal conspired and was actively involved in use and concealment of proceeds of crime." 

“The ED case also reveals that he was involved in his personal capacity as well as convenor of AAP," the order said.

Kejriwal had earlier questioned the timing of the arrest that came just ahead of the Lok Sabha Elections 2024.  Reacting to this, the court said, “Petitioner has been arrested in money laundering case and court has to examine his arrest and remand as per law irrespective of timing of elections."

Reacting to Kejriwal's argument casting doubt on the statements of “approvers" in the excise policy case, the court said the statements of “Raghav Magunta and Sarath Reddy are approver statements which were recorded under the PMLA as well as Section 164 CrPC".

“To cast doubt on the manner of recording statement of approver would amount to casting aspersions on the court and judge," the order added. “The law of approver is over 100 years old and not one year old. It cannot be suggested that it was enacted to implicate the present petitioner (Kejriwal)," it added.

Purulia: West Bengal Chief Minister Mamata Banerjee on Sunday alleged the central investigating agencies were asking TMC leaders to either join the BJP or face action.

Addressing an election rally in Purulia district, she alleged agencies such as the ED, CBI, NIA and the I-T Department were working as 'arms' of the BJP.

"Agencies such as the NIA, ED and CBI are being used to harass TMC leaders. They are carrying out raids without prior information, and barging into houses. What the women would do if someone entered their house when everyone was asleep in the dead of night?" she asked.

Banerjee was referring to Saturday's incident in Bhupatinagar where a team of the NIA was attacked by a mob when it went to arrest two accused in a blast case.

"The agencies are asking our leaders and activists to either join the BJP or face action," she alleged.

Asking people not to fall for any provocation, Banerjee alleged the BJP was fanning communal passions during Ram Navami.

The chief minister also accused the BJP-led government at the Centre of depriving West Bengal of funds for MGNREGA and PM-Awas schemes.

She said the state government will provide Rs 1.2 lakh for building houses for the poor.

"The EC will not give permission to us to give the money now. After the elections, we will construct the houses of the poor," she said.
