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 such non-uniqueness poses challenges, they also provide avenues for improving skill; in particular, calibration and customization can improve

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 in damage to crops, infrastructure and mines in Australia and other parts of Asia.

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.

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 the winter-spring transition period.

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 on an asteroid to explore its surface, search for minerals and even learn the skills they may need to destroy it should one pose a threat to the Earth, ‘The Daily Telegraph’ reported.

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 third successive year and a chance to rein in food inflation.
“It will hit Kerala in the first week of June with an error window of 2-3 days,” said India Meteorological Department director general LS Rathore.

South Asian emissions of fossil fuel SO2 and black carbon increased

Human activities are releasing tiny particles (aerosols) into the atmosphere. These human-made aerosols enhance scattering and absorption of solar radiation. They also produce brighter clouds that are less efficient at releasing precipitation. These in turn lead to large reductions in the amount of solar irradiance reaching Earth's surface, a corresponding increase in solar heating of the atmosphere, changes in the atmospheric temperature structure, suppression of rainfall, and less efficient removal of pollutants.

India’s Cabinet has given its approval to a “National Monsoon Mission,” which will equip the weather department with high-end computers, radars and scientific manpower to generate more detailed and accurate forecasts.

India’s current antiquated methods of forecasting the all-important monsoon rains is getting a re-vamp.

No other weather phenomenon generates as much excitement among policymakers and economists, given that it holds the key to farm output, a sector employing half the country’s workforce.

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 holy grail of astronomy.
