The original application was registered suo-motu based on the news item titled "Nayar …
Scientists studying tree rings to reconstruct the past have found that major volcanic eruptions can boost rains in Southeast Asia, challenging a common perception of volcanoes as purely destructive forces. Studies in the past have shown massive eruptions such as the 1815 Tambora blast, and Krakatau in 1883, both in …
Organic aerosol particles are ubiquitous in the atmosphere. In forests, such particles can occur in solid form — a finding that will lead to a re-evaluation of how they are formed, and their properties and effects.
Secondary organic aerosol (SOA) particles are formed in the atmosphere from condensable oxidation products of anthropogenic and biogenic volatile organic compounds (VOCs). On a global scale, biogenic VOCs account for about 90% of VOC emissions and of SOA formation (90 billion kilograms of carbon per year). SOA particles can scatter …
Almost five months after the state-of-the-art radar, S Band, arrived in the city for more accurate weather prediction, it seems that the technology will not be put to use this monsoon. The reason: India Meteorological Department is yet to finish the earthing and wiring which would make the radar operational. …
RAIN comes from clouds. But where do clouds come from? Through the process of evaporation and transpiration, water vapour rises higher into the atmosphere, deposits on fine particles, such as dust, air pollution, pollen and bacteria, condenses and forms the cloud. These particles called aerosols act as a seed to …
Using satellite data, scientists have produced a first-of-its kind map that details the height of the world's forests. Although there are other local- and regional-scale forest canopy maps, the new map is the first that spans the entire globe based on one uniform method. The map, based on data collected …
Divya Gandhi Bangalore: The spectre of global warming has generated some rather novel emergency fix-it proposals to stave off solar radiation from reaching the Earth. These include placing mirrors in space to reflect sunlight, injecting sulphate aerosols in the stratosphere and other such techniques of geo-engineering. A research article by …
The seasonal variability of phytoplankton biomass in the Arabian Sea, though a well researched topic, its inter-annual variability is less explored and understood. Analysis of the satellite-derived chlorophyll pigment concentration in the Arabian Sea during 1997
With growing importance being placed on climate change and mitigation strategies, India's space agency ISRO is in the process of launching a satellite to study greenhouse gases. "In the next 2-3 years, ISRO will carry out the first of the launches which will be dedicated to (studying) greenhouses gases like …
Richard Black Simulation showed temperature falling decades after CO {-2}'s decline Canada and Russia would receive more rain and snow Impacts of manmade greenhouse warming on rainfall would endure long after temperatures fell, a study suggests. The U.K. Met Office scientists constructed a hypothetical future in which carbon dioxide levels …
As Air Cools Behind Propellers Or Over Wings, Water Droplets Freeze & Drop Towards The Earth Washington: Jet aircraft make odd-shaped holes in clouds and cause rain or snow as they climb or descend in the skies under certain atmospheric conditions, according to a new American study. The key ingredient …
The world is currently experiencing the Ice Age called the Quarternary period. There have been five ice ages since the planet was born. Each of them was characterized by periods of lower temperatures and glacier formation, interspersed with periods of higher temperature. The glacial periods used to occur roughly at …
STATISTICAL PROOF: From 1995 to 2009, the model predicted a mean of 13.7 named storms of which a mean of 7.8 were hurricanes. In reality, the average during this period was 13.8 named storms with a mean of 7.9 hurricanes. Florida State University scientists who have developed a unique computer …
Not Soot And Dust, But Bugs Serve As Nuclei For Raindrops Jim Robbins Bozeman (Montana): Walking across the campus of Montana State University here, David Sands, a plant pathologist, says the blanket of snow draped over the mountains around town contains a surprise. The cause of most of it, he …
The cyclonic storm Laila reached Andhra Pradesh coastline on Thursday and showed definite signs of weakening but weather scientists said its behaviour over the next two days would be extremely crucial, especially from the point of view of its impact on the monsoon. The cyclone is most likely to move …
RASHME SEHGAL NEW DELHI Climate experts at the first South Asian Climate Outlook Forum (SACOF) meet comprising South Asian countries who met in Pune last week believe the monsoon this year could be less than normal. Countries attending the meet included Pakistan, Nepal, Bangladesh and Sri Lanka, all of whom …
