The World Meteorological Organization’s State of the Climate in Asia 2024 report warns that the region is warming nearly twice as fast as the global average, driving more extreme weather and posing serious threats to lives, ecosystems, and economies. In 2024, Asia experienced its warmest or second warmest year on …
The national government did not carry out an environmental impact assessment before dredging sand in the Indian Ocean at the South Coast, a lobby has said. The Community Organisation for Nature Conservation said the government did not adhere to international laws of nature conservation. Last year, the government was criticised …
Dr Suryachandra Rao, Associate Mission Director, Monsoon Mission, at the Indian Institute of Tropical Meteorology (IITM), explains a key atmosphere-ocean phenomenon. What is the Indian Ocean Dipole (IOD)? It is an atmosphere-ocean coupled phenomenon in the tropical Indian Ocean (like the El Nino is in the tropical Pacific), characterised by …
Private forecasters are counting on temperature changes in the Indian Ocean to strengthen the monsoon current like it did in 1997, when rainfall was normal, despite a strong El Nino. While forecasters are divided about the monsoon outlook, experts say that India has become less vulnerable to monsoon rain as …
Monsoon watchers are scanning the Indian Ocean for any sign that could potentially reduce the impact on seasonal rains from a raging El Nino away in the equatorial Pacific. A few models have suggested that the Indian Ocean may be priming for a positive dipole event which can save the …
The weather office revised its southwest monsoon forecast to 88 per cent of average rainfall with the El Nino effect apparently having taken hold, presenting the Narendra Modi government with a challenge in case the prediction comes true. The new estimate is lower than the 93 per cent forecast by …
Prospects are firming that the latest El Nino event may leave much of Australia drier, with conditions in the Indian Ocean possibly reinforcing those in the Pacific, the Bureau of Meteorology says. In its fortnightly update, the bureau said the El Nino continues to strengthen in the tropical Pacific and …
The monsoon is likely to arrive in Kerala on May 30 -as predicted by India Meteorological Department -but it may be weak because of El Nino's impact, IMD scientists have indicated. Experts from Skymet, a private weather agency , too said the monsoon's first surge over Kerala would be mild …
Why this weird weather? Why have western disturbances - the extra-tropical storms that originate in the Mediterranean and the Atlantic oceans - been lashing us again and again, with devastating impacts on agriculture? Is this normal? Or has weird weather become the new definition of normal? The India Meteorological Department …
The world’s oceans are playing a game of hot potato with the excess heat trapped by greenhouse gas emissions. Scientists have zeroed in on the tropical Pacific as a major player in taking up that heat. But while it might have held that heat for a bit, new research shows …
The monsoon is likely to hit India two days ahead of its normal onset date, the India Meteorological Department announced on Thursday even as the possibility of below-par rainfall grew, with both IMD and US forecasters predicting a greatly increased chance of El Nino conditions persisting through the summer. "The …
The northeastern part of the Indian Ocean, i.e. the Bay of Bengal (BoB) is located near some of the most complicated tectonic zones on the Earth. An earthquake of magnitude ~6.0 occurred on 21 May 2014 near the coast of Odisha. Occasional moderate to large earthquakes in BoB highlight the …
When does an El Nino (warming of the east and equatorial Pacific) create widespread rain deficit over India during the monsoon? K Srikanth, Chennai-based blogger and weather enthusiast, has found from a study that between 1950 and 2012, five years have seen 50 per cent or more meteorological divisions suffer …
This paper presents key results from analysis of surface meteorological observations collected in the Northern Arabian/Persian Gulf (N Gulf; Kuwait, Bahrain, and NE Saudi Arabia), which spans a 40-years period (1973–2012). The first part of this study analyzes climate variability in the N Gulf, and relates them to teleconnection patterns …
The world's oceans are heating at the rate of two trillion 100-watt light bulbs burning continuously, providing a clear signal of global warming, according to new study assessing data from a global fleet of drifting floats. The research, published on Tuesday in the journal Nature Climate Change, used data collected …
Energy is key to prosperity, and the discovery and use of fossil fuels in the past few centuries has generated tremendous wealth. Yet, this energy paradigm has now become a liability that threatens the very sustainability of all it enabled. This report analyses the impacts of fossil fuel energy in …
Marine debris, mostly consisting of plastic, is a global problem, negatively impacting wildlife, tourism and shipping. However, despite the durability of plastic, and the exponential increase in its production, monitoring data show limited evidence of concomitant increasing concentrations in marine habitats. There appears to be a considerable proportion of the …
Along the continental margins, rivers and submarine groundwater supply nutrients, trace elements, and radionuclides to the coastal ocean, supporting coastal ecosystems and, increasingly, causing harmful algal blooms and eutrophication. While the global magnitude of gauged riverine water discharge is well known, the magnitude of submarine groundwater discharge (SGD) is poorly …
THE “Great Pacific Garbage Patch” lies off the coast of California. But it is not the only place where a system of rotating ocean currents, known as gyres, concentrate floating material, particularly plastic detritus dumped into the sea or washed out from rivers. There is an awful lot of it: …
Unprecedented wet conditions are reported in the 2014 summer (December–March) in South-western Amazon, with rainfall about 100% above normal. Discharge in the Madeira River (the main southern Amazon tributary) has been 74% higher than normal (58 000 m3 s−1) at Porto Velho and 380% (25 000 m3 s−1) at Rurrenabaque, …
Kathmandu: Maldives believes it is time to walk the talk on climate policies jointly-supported by all South Asian countries, Maldivian President Abdulla Yameen said at the 18th SAARC Summit here Wednesday. Yameen, who also officiated as the outgoing chair during the first part of the opening ceremony of the South …
