New Delhi: The odds of an El Nino phenomenon developing in July through September and potentially affecting the Indian monsoon are dead-even at 50-50, offering hope that India’s agriculture and economy may yet escape a crippling blow. A stuttering economy has seen heightened attention on the Pacific warming, known to …
So far, 2012 has been the warmest year the United States has ever seen, with the warmest spring and the second-warmest May since record-keeping began in 1895, the U.S. National Oceanic and Atmospheric Administration reported on Thursday. Temperatures for the past 12 months and the year-to-date have been the warmest …
New Delhi: The Indian Meteorological Department (IMD) announced the onset of monsoon on Tuesday following a four-day delay in clouds gathering strength over the southern shores. The delay, though vital, suggests that the chances of the country enjoying a normal monsoon remain even as the clouds progress northwards. The IMD …
Rains hit Kerala; Met to decide on official declaration in 24 hrs Evenas rains have started along the west coast of Kerala, India Meteorological Department (IMD) will still take at least 24 hours for the official declaration of monsoon. “Rains have started at the 14 designated stations in Kerala, which …
Delay Not Drastic, Assures IMD Kochi/Pune: After keeping the country and the powersthat-be on tenterhooks, the skies have thrown up a positive sign: the south-west monsoon which should have hit Kerala five days ago will arrive in the next 48 hours, with June 6 being the farther limit. On Sunday, …
The most used temperature and salinity climatology for the world ocean, including the Indian Ocean, is the World Ocean Atlas (WOA) (Antonov et al 2006, 2010; Locarnini et al 2006, 2010) because of the vast amount of data used in its preparation. The WOA climatology does not, however, include all …
The failure of atmospheric general circulation models (AGCMs) forced by prescribed SST to simulate and predict the interannual variability of Indian/Asian monsoon has been widely attributed to their inability to reproduce the actual sea surface temperature (SST)–rainfall relationship in the warm Indo-Pacific oceans. This assessment is based on a comparison …
A detailed analytical study of major cations (Ca2+, Mg2+, Na+, K+) and anions (SO2− 4 , HCO−3 , Cl−, NO−3 ) of meltwater draining from Gangotri Glacier was carried out to understand major ion chemistry and to get an insight into geochemical weathering processes controlling hydrochemistry of the glacier. In …
Investigations of aerosol optical and physical characteristics using the application of Ångström formula and second order polynomial fit were carried out from April 2006 to March 2009 at Mohal in the Kullu valley. The measurements of spectral aerosol optical depths (AODs) were conducted using multiwavelength radiometer (MWR). The AOD at …
The paper presents the nature of annual cycles of tropospheric ozone, cloud occurrences, NO2, rainfall, SO2, SPM, CO, non-methane hydrocarbon and surface solar radiation for the period October 2004 to June 2009 over Alipore (22.52°N, 88.33°E), India. Annual cycle of low-level cloud occurrences depicts that the low-level cloud over Alipore …
New Delhi: It’s that time of the year when the scorching sun saps the energy out of you. But if you have been feeling hotter in certain parts of the city, blame it on the ‘urban heat island (UHI) effect.’ Heat islands — as they have been termed by scientists …
Washington: Astronomers claim to have found evidence that suggest a planet four times the size of Earth may be skirting the edges of the solar system beyond Pluto. The planet, which is too distant to be easily spotted by Earth-based telescopes, could be gravitationally tugging on small icy objects past …
Advance and accurate forecasts of rainfall can aid many sectors, from agriculture to disaster mitigation. However, given the tremendous spatial variability of rainfall, only forecasts at high resolution can serve users’ needs. The skill of a dynamical forecast model depends on the resolution and varies from region to region. While …
Melbourne has had its wettest May day for 17 years, with more rain expected into the weekend. Twenty-eight millimetres of rain fell on the CBD on Friday, the most in a May day since 1995, while the top temperature of 11C degrees just before 2.30pm (AEST) made it the city's …
Australia's Bureau of Meteorology said the climate models it monitors indicate a possible return of the El Nino weather pattern, often linked to heavy rainfall and droughts, in the second half of 2012. The last severe El Nino in 1998 killed more than 2,000 people and caused billions of dollars …
The primary drivers of the Northern Hemisphere expansion of the tropical climate zone over the past several decades are shown to be the recent increases in black carbon aerosols and tropospheric ozone rather than in greenhouse gases, which contribute to a lesser extent.
Astronauts Being Trained For Mission To Look For Minerals, Get Info On How To Destroy It. Washington: Nasa is reportedly training a team of astronauts for a mission to land on an asteroid by the end of the next decade. The US space agency is training the astronauts to land …
Met chief says El Nino may affect showers The monsoon is likely to hit the southern tip of the country on time in the first week of June, said India’s top weather department official on Thursday, a week before the official forecast, lifting hopes of better farm output for the …
Methane (CH4) uptake by steppe soils is affected by a range of specific factors and is a complex process. Increased stocking rate promotes steppe degradation, with unclear consequences for gas exchanges. To assess the effects of grazing management on CH4 uptake in desert steppes, we investigated soil-atmosphere CH4 exchange during …
Washington: Earth-like rocky planets that humans could live on may be more common in the universe than stars, says an international team of planetary scientists which included an Indian-origin researcher. Aditya Chopra at Australian National University and colleagues claim that determining whether these planets are habitable has become the new …
