India’s active covid cases dips to 85,680 - 0.20% of the total infections

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.

Dubai: Dubai was slapped by heavy floods as the United Arab Emirates (UAE) was hit by extremely heavy rains on Tuesday. The desert city received over a year and a half's worth of rain in just a day even as heavy thunderstorms lashed other parts of the UAE.

Roads turned into rivers as they were filled up with water. Shopping centres like Dubai Mall and Mall of the Emirates were also seen flooding.

Schools across the UAE have been shut and are expected to remain closed on today as well.

According to a report by India Today, Dubai airport received about 100 mm of rain in just 12 hours on Tuesday and a total of 160 mm in the last 24 hours.

On average, Dubai receives about 88.9 mm of rain in a year, which concludes that the city received more than a year's rain in a day.

Dubai International Airport said on Wednesday it was experiencing significant disruption due to bad weather and was working to restore normal operations as quickly as possible.

Flights have been delayed or diverted and impacted by displaced crew, the airport said in a statement, adding that recovery would take some time.

Dubai's Emirates airline said that it was suspending check-in for passengers departing the airport from 8 am (0400 GMT) on Wednesday until midnight due to operational challenges caused by the bad weather and road conditions.

Dubai International was temporarily diverting arriving flights on Tuesday evening because of a storm, and operations were suspended for 25 minutes earlier in the day.

According to India Today, the airport stopped flight operations and issued a warning earlier today on X.

The Dubai International Airport requested the passengers to check their flight status.

Employees in Dubai have been told to work from home.

The UAE Government took to X and said, "Based on the directives of the Council of Ministers, it was decided to extend remote work until tomorrow, Wednesday, April 17, for all federal government employees, with the exception of jobs that require presence at the workplace, taking into account the weather condition that the country is going through."

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.
