Order of the National Green Tribunal in the matter of Nizamuddin West Association Vs Union of India & Others dated 16/04/2025. The matter related to desilting of 24 drains with special focus on two drains - Kushak drain and Sunheri Pul drain before the monsoon. The court was informed that …
Forest fire, an anti environmental human activity, is becoming a great threat for eco restoration of Cherrapunjee-the site famous as wettest place on earth. Human's carelessness, negligence and ignorance are the main causes of annual ground fire resulting into pronounced and prolonged ill effect on climate, land use, land cover, …
In this new study IMD examines district-wise and all India drought climatology over India for southwest monsoon season using using Percent of Normal(PN) & Standardized Precipitation Index(SPI).Compares drought climatology based on SPI with that based on PN to show that SPI is a better index for monitoring drought conditions over …
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, …
BOMDILA, Feb 2: A three-day district level disaster management training on search and rescue operations and first aid began since yesterday here at Bomdila in West Kameng district to acquaint and make people aware of the risk factors, especially in the backdrop of the approaching monsoon, which is the most …
South Asian summer monsoon (June through September) rainfall simulation and its potential future changes are evaluated in a multi-model ensemble of global coupled climate models outputs under World Climate Research Program Coupled Model Intercomparison Project (WCRP CMIP3) data set. The response of South Asian summer monsoon to a transient increase …
How do climate fluctuations affect DDT and hexachlorocyclohexane (HCH) distribution in the global scale? In this study, the interactions between climate variations and depositions of DDT and HCH in ice cores from Mt. Everest (the Tibetan Plateau), Mt. Muztagata (the eastern Pamirs) and the Rocky Mountains were investigated. All data …
The present study deals with the impact of agriculture crop residue burning on aerosol properties during October 206 and 2007 over Punjab state, India using ground based measurements and multi-satellite data.
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. …
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.
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 …
For the last two decades the world has been trying to explain how arsenic leaches into groundwater in the Ganga-Meghna-Brahmaputra floodplain. Solutions, however, are very few. An estimated 100 million people are still at risk from contamination. The latest research says floodwaters can remove arsenic. A team headed by Linda …
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.
P. Sunderarajan THIRUVANANTHAPURAM: The India Meteorological Department is set to introduce an additional feature to its forecasts during monsoon. Shailesh Nayak, Secretary, Ministry of Earth Sciences, said here on Tuesday that from this year, farmers would also get forecasts of active and break phases of monsoon 10-15 days in advance. …
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 …
Following a unified approach, an objective criterion has been developed for the determination of yearwise onset and withdrawal dates of the summer monsoon over the 19 subregions across India. In total 14 meteorological parameters are considered in the development of the objective criteria, two of which represent heating over south …
General Circulation Models (GCMs) are tools designed to simulate time series of climate variables globally, accounting for effects of greenhouse gases in the atmosphere. They are good at continental and hemispherical spatial scales and incorporate a large proportion of the complexity of the global systems.
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 …
This document by IMD, contains the highlights of temperatures during the year 2009. It presents the monthly temperature profile with spatial pattern over India. For full report: http://www.imd.gov.in/doc/warm2009.pdf
