Short affidavit on behalf of the Rajasthan State Pollution Control Board (RSPCB) in terms of the National Green Tribunal order dated January 22, 2025. The application was registered suo motu by the NGT on the basis of a news item titled "Toxic kilns pollution Aravallis; wildlife and locals suffer" appearing …
A new study has revealed that climate change could be blamed for extreme and slow weather pattern changes in places like Texas and India. Scientists predicted that more of these extreme weather fluctuations like the flooding that killed at least 30 people recently in the southern plains, while damaging or …
Estimation of extremely high rainfall (point or areal) is one of the major components of design storm derivation. The estimation of Probable Maximum Precipitation (PMP) involves selection of heavy rainstorms and its maximization for the moisture content during the rainstorm period. These heavy rainstorms are nothing but the widespread heavy …
This paper looks at the crucial issue of dry-season groundwater-availability in the state of Maharashtra, India. We look at the two key hydro-climatological measurements which are used to implement groundwater policy in the state, viz., water levels in 5000+ observation wells across the state and aggregate rainfall data. We see …
Aimed at reducing deficiencies in representing the Madden-Julian oscillation (MJO) in general circulation models (GCMs), a global model evaluation project on vertical structure and physical processes of the MJO was coordinated. In this paper, results from the climate simulation component of this project are reported. It is shown that the …
Understanding the changing nature of the intraseasonal oscillatory (ISO) modes of Indian summer monsoon manifested by active and break phase, and their association with extreme rainfall events are necessary for probabilistic estimation of flood-related risks in a warming climate. Here, using ground-based observed rainfall, we define an index to measure …
Question raised in Rajya Sabha on impact of El Nino in various states, 07/05/2015. The details of the observed impact of El Nino in various meteorological subdivisions is given in Annexure-1, that shows the sub-division wise climatological probabilities of monsoon season rainfall in three pre-defined rainfall categories (below normal, normal …
Usha Ghatowar smiles wryly when asked about the pay she earns picking leaves at a colonial-era tea garden in Assam. “Do you think `3,000 is enough when your monthly expenses can be double that?” she mumbles, as she puts on her “jaapi” hat of woven bamboo and palm leaves and …
Climate change includes not only changes in mean climate but also in weather extremes. For a few prominent heatwaves and heavy precipitation events a human contribution to their occurrence has been demonstrated. Here we apply a similar framework but estimate what fraction of all globally occurring heavy precipitation and hot …
India gets 70% of its annual rainfall in the monsoon, which irrigates half the country's farmlands. In 2014, IMD had forecast that rainfall in June-September monsoon season would be 95% of the 50-year average, which is below normal rainfall. In its August review of the forecast, IMD cut the prediction …
India gets 70% of its annual rainfall in the monsoon, which irrigates half the countrys farmlands. Last year, IMD had forecast that rainfall in June-September monsoon season would be 95% of the 50-year average, which is below normal rainfall. In its August review of the forecast, IMD cut the prediction …
All of the representative concentration pathways (RCPs) assume that future emissions of aerosols and aerosol precursors will decline sharply. There is considerable evidence that historically increasing aerosols have substantially affected tropical precipitation, but the effects of projected aerosol declines have received little attention. We compare projections forced by the medium-low …
Fossils from the ocean floor are yielding clues to the Indian monsoon millions of years ago. Samples drilled from beneath the Indian Ocean are being used to reconstruct past rainfall and temperature records. Scientists are studying how the Indian monsoon behaved in the past, to shed light on the impact …
Climate change is making drought conditions in south-west and south-east Australia worse, with serious ramifications for people’s health and the agriculture industry, a new paper has warned. The Climate Council report states that since the mid-1990s, south-east Australia has experienced a 15% drop in rainfall during late autumn and early …
The Karakoram and the Himalayan mountain range accommodate a large number of glaciers and are the major source of several perennial rivers downstream. To interactively describe to response of glaciers to climate change, a glacier parameterization scheme has been developed and implemented into the regional climate model REMO. The scheme …
Rainfall is increasing in the tropics across the world with the rise attributed to more big thunderstorms, new research by an Australian-led team has found. While observations and models have found that "wet gets wetter" and "warmer gets wetter", the mechanism of what has been going on has been unclear. …
Regional climate models (RCMs) are considered to be more useful than general circulation models for assessing impacts of climate change scenarios in agriculture. In this communication, the climatic outputs of an RCM–PRECIS (providing regional climates for impact studies) model were analysed by comparing its baseline simulation daily weather data on …
Rainfall variations in the Garhwal Himalaya, Uttarakhand were studied for a period of six years from 2008 to 2013. The rainfall data were obtained through a dense network of rain gauges installed by India Meteorological Department (IMD), New Delhi, are spreaded over seven districts of Uttarakhand, combined with the data …
The UN has urged world leaders to rethink water policies or face a 40 per cent shortfall in just 15 years. A combination of low underwater reserves and erratic rainfall patterns caused by climate change, has brought the problem to the fore according to a report which stresses how water …
This paper presents key results from analysis of surface meteorological observations collected in the Northern Arabian/Persian Gulf (N Gulf; Kuwait, Bahrain, and NE Saudi Arabia), which spans a 40-years period (1973–2012). The first part of this study analyzes climate variability in the N Gulf, and relates them to teleconnection patterns …
Landslides, floods, and droughts are recurring natural disasters in Nepal related to too much or too little water. The summer monsoon contributes more than 80% of annual rainfall, and rainfall spatial and inter-annual variation is very high. The Gandaki River, one of the three major rivers of Nepal and one …
