The elevation of the Tibetan plateau is thought to cause its surface to serve as a heat source that drives the South Asian summer monsoon, potentially coupling uplift of the plateau to climate changes on geologic timescales. Here, however, an atmospheric model is used to show that flattening of the …
Received wisdom about the main driver of the South Asian monsoon comes into question with a report that tests the idea that the Himalayas, not the Tibetan plateau, are the essential topographic ingredient.
Ranchi, Jan. 10: Scientists of Birla Institute of Technology (BIT), Mesra, are getting ready to witness the solar eclipse that will occur on January 15, a day after Makar Sankranti.

P. Venugopal THIRUVANANTHAPURAM: With the problem of climate change now turning into an increasing reality, the India Meteorological Department (IMD) is working on the development of a model that can forecast the subtleties of the phenomenon with a fair degree of accuracy into the next five or 10 years, according …
The 2009 southwest monsoon recorded the third highest deficient all India southwest monsoon season rainfall (-22% of LPA) during the period 1901-2009. All the monsoon months except July recorded large deficient rainfall. Region wise, except south Peninsula, all other homogeneous regions recorded much below normal rainfall. Activity of depression was …
The southern Western Ghats tropical montane cloud forest sites (Gavi, Periyar, High wavys and Venniyar), which are characterized by frequent or seasonal cloud cover at the vegetation level, are considered one of the most threatened ecosystems in India and the world. Three out of four montane cloud forest sites studied …
Pune Refusing to put the blame on the officers of India Meteorology Department (IMD) for the wide deviation in the prediction of rains, Minister of State for Earth Sciences Prithviraj Chavan on Wednesday said it would be inappropriate to pull up someone for weather prediction.

Halogenated gases currently contribute 12% to overall radiative forcing. While actions under the Montreal Protocol on Substances that Deplete the Ozone Layer (Montreal Protocol) are already addressing CFCs and HCFCs, atmospheric concentrations of some HFCs (hydrofluorocarbons) are rising rapidly, by more than 23% each year. A global agreement to phase …
Focuses on the issue of phasing down hydrofluorocarbon (HFC) use. It also provides a summary of the UN DPI non-governmental organization briefing on the ozone layer and climate change held on 18 June 2009, including presentations as well as the question and answer session held with ozone experts.
Presents study consists the results of the Sun photometer measurements of aerosol optical depth (AOD) over the northern Arabian Sea during December 4-17, 2004 along with OCEANSAT-1 Ocean Colour Monitor (OCM) data derived AOD estimates. In-situ AOD ranged between 0.15-0.38 at 500-nm wavelength (with a mean of 0.274). Relatively higher …
The IMD overlooked and ignored data on Cyclone Phyan, leading to the loss of almost a hundred lives, says SUJAY GUPTA Disaster is often the distance between a cosy bedtime story and an early morning wake-up call. On the intervening night of December 10 and 11, Goa was on the …
Scientists have blamed this year's drought on a rare fierce war of temperatures over the Bay of Bengal and the Indian Ocean, which prevented formation of monsoon clouds. Despite its early onset over Kerala, the southwest monsoon played truant for most of June this year due to unusual heating up …
