Order of the National Green Tribunal in the matter of News Item titled “CSE report finds dangerous increase in ozone pollution across urban India” appearing in Down to Earth dated 06.08.2024. The Principal Bench of the NGT heard the matter on March 21, 2025. In the original application, registered suo …
Strong dust-raising wind harassed the Guwahatians today signaling the advent of the westerly wind, known in this part of the globe as pachowa botah. Regional Meteorology Centre (RMC) sources here said that during the day time today, the strong dust-raising westerly wind prevailed over the NE region, blowing at a …
In the early 1970s, scientists warned that anthropogenic chemicals containing chlorine (Cl) would lead to destruction of stratospheric ozone (O3), the protective veil that reduces the amount of harmful ultraviolet (UV) rays that reach the Earth
A recent report by the Indian Meteorological Department (IMD) has pointed out that 2009 received the third worst rainfall since 1901, behind 1918 when there was a 25 per cent deficiency and 1972 when the deficiency was 24 per cent of the Long Period Average. The report, released in January, …
Pune The Indian Meteorological Department (IMD) has embarked on a nationwide project to install automatic rain gauge stations across the country to ensure there is real time mapping of the rainfall. The project that began four months ago is part of its efforts to modernise and enhance weather mapping capabilities …
As part of its modernisation programme aimed at enhancing weather monitoring facilities, the India Meteorological Department (IMD) is installing a network of 187 automatic rain gauge stations across the state. When installed, the network would help in accurate collection of rainfall data from various parts of the state. It would …
The more one irrigates his lands, lower the amount of rainfall he can expect in the coming years. While agricultural lands are seeing drier weather, Indian cities are getting short but intense periods of rain and the subsequent water logging. This is the irony that a group of researchers explain. …
New Delhi: With the last spell of fog on January 27 and 28, this month is now officially the foggiest since the 1960s, having clocked a total of 172 hours of below 200 m visibility. The good news is that the Met department does not foresee too many dense fog …
Francis and Gadgil1 have made many interesting correlations of meteorological variables and events, and have proposed that unfavourable SST (sea surface temperature) gradient between the Bay of Bengal and EEIO (eastern equatorial Indian ocean) led to the large deficit of monsoon rainfall in 2009.
High concentrations of ozone in the troposphere are toxic and act as a greenhouse gas. Anthropogenic emissions of ozone precursors have caused widespread increases in ozone concentrations since the late 1800s, with the fastest-growing ozone precursor emissions currently coming out of east Asia. Much of the springtime east Asian pollution …
Springtime ozone levels in the lower atmosphere over western North America are rising. The source of this pollution may be Asia, a finding that reaffirms the need for international air-quality control.
Vinson Kurian Japanese researchers have indicated the possibility of La Nina, the alter ego of monsoon-buster El Nino, to unfold over the equatorial Pacific later this year. La Nina, which represents shift of warmer sea-surface temperatures to the west equatorial Pacific, has generally coincided with a normal Indian monsoon, though …
The Meteorological Department today installed a super-computing device, which will upgrade its short-range weather prediction to seven days. The IMD, which turned 135 today, inducted a High Power Computing System (HPCS) at its headquarters that will help weathermen make predictions about rain, fog, smog and cyclone situations at least seven …
On the occasion of the 135th Foundation Day of the indian meteorological department (IMD), minister for science and technology and earth sciences Prithviraj Chavan inaugurated India's first mega computer (IBM P6) which will go long away in providing accurate weather predictions. Speaking on the occasion, the minister said the this …
For Indian Space Research Organisation (ISRO) the rare and longest solar eclipse on Friday is going to be crucial to study the atmospheric changes and its consequences before, during and after the eclipse. According to ISRO officials, the premiere space research agency, is going to launch a series of rockets …
Scientists around the world have been confused by the role of wind and pollutants on rainfall. But now they have a model. It shows that wind shear—a change in wind speed and direction between different altitudes—plays a crucial role in the whole process. A research team from Pacific Northwest National …
