The report discusses the climate condition over Indian region during the year 2023. Notably, global temperatures soared to exceptionally high levels during this period (WMO.No.1347). The India Meteorological Department continuously monitors weather and climate over Indian region. The annual mean land surface air temperature averaged over India during 2023 was …
The India Meteorological Department (imd) has predicted that the southwest monsoon for 2006 will be below normal. The June-September rainfall is estimated at about 830 millimetres (mm), instead of the normal 890 mm. imd also says there is a chance that the rainfall will be below 800 mm. If that …
The Uttaranchal government has declared 56 of the state's 78 tehsil s drought-hit. A Union government team recently noted that more than 50 per cent of the rabi crop in Nainital district has been affected. The state government has responded with an aid package of Rs 33 crore. But experts …
This report presents the dynamic ground water resources of India based on GEC'97 (Ground Water Exploitation Committee)with base year as 2004. It identifies the areas where ground water development is at low key and the areas, where ground water development is alarmingly high. The estimation for the individual state was …
Maharashtra is among the few states in India that has enacted and implemented legislation to regulate the use of groundwater. The Act, known as Maharashtra Groundwater (Regulation for Drinking Water Purposes) Act 1993 stipulates inter alia, a minimum distance of 500 metres between a public drinking water source (PWS) and …
The present book on rainwater harvesting, is the perfect guide where detailed plans for adopting very economical rain water harvesting schemes for houses of different types is given.
Rain gardens have been recommended as a best management practice to treat stormwater runoff. Replicate rain gardens were constructed in Haddam, CT, to treat roof runoff. The objective of this study was to assess whether the creation of a saturated zone in a rain garden improved retention of pollutants. The …

Being an integral effect of sub-seasonal rain spells over the season, the seasonal mean south Asian monsoon (SAM) rainfall could be affected by change in the length of the rainy season (LRS). An objective definition of the duration of the SAM season has, however, been lacking. Here we show that …
an international team of scientists has devised a model to better predict cloud and rain formation. An improved understanding of clouds is vital to quantify rainfall in short-range weather forecasts. Incidentally, none of the rain forecast models the world over could accurately predict the deluge that flooded Mumbai on July …
Feasibility of harvesting roof top water in an engineering college campus is studied using a stochastically generated daily rainfall series. It has been shown that even though sufficient amount of water is available, possibility of harvesting rainwater is limited because of limitations in the storage that can be provided. It …
Release of water from Maharashtra's reservoirs following heavy rain flooded Karnataka, especially Bijapur, Raichur, Gulbarga and Belgaum districts. Seven other districts were also affected. The death toll touched 111 on August 6, 2005. Villages along the Krishna, Bhima and Ghataprabha rivers were the worst hit. Crops worth Rs 160 crore …
The southwest monsoon current in the form of a crossequatorial low level jetstream (LLJ) with its core at an altitude of about 1.5 km and core wind speeds of 80
The authors in this paper present a factual and a brief review of the extreme weather events that occurred in India during the last 100 years (1991-2004). The socio-economic impacts of the extreme weather events such as floods, droughts, cyclones, hail storm, thunderstorm, heat and cold waves have been increasing …
South Asian emissions of fossil fuel SO2 and black carbon increased 6-fold since 1930, resulting in large atmospheric concentrations of black carbon and other aerosols. This period also witnessed strong negative trends of surface solar radiation, surface evaporation, and summer monsoon rainfall. These changes over India were accompanied by an …
Four years ago, this magazine's editor, environmentalist Anil Agarwal, wrote a scathing comment after the Bhuj earthquake: "Disasters come and go but our government has become a permanent disaster". While we are vulnerable to natural disasters - cyclones, earthquakes, floods or droughts, and now the tsunami - these temporary and …
The paper describes the effect of rains on vegetal cover, different traditional practices and soil properties in the dry and monsoon period. Seven landuse systems i.e. open pine forests, tea plantation, rainfed agriculture, degraded land, grassland, recently restored site and a bare land were identified in the Bhetagad watershed of …
though the India Meteorological Department (imd) could not predict the erratic mid-course behaviour of the southwest monsoon this year, it might actually benefit from this failure! The imd's inability to foresee a shortfall of rains in July, the month of sowing of kharif crops, has prompted Union minister of state …
an international study has identified north India as one of four hotspots worldwide where rainfall seems to be directly linked to the amount of moisture in the soil. The finding of the ongoing Global Land-Atmosphere Coupling Experiment (glace) comes at the time when India is contemplating to improve its region-wise …
function map() { var popurl="image/20040815/16-map.jpg" winpops=window.open(popurl,"","width=550,height=500,scrollbars=yes") } the lacklustre performance of the South West monsoon in July 2004 has left Indian weathermen in a lurch. A section of the meteorological scientific community feels that in addition to the damage it has already done to the sowing season, the deficient rains …
scientists at the Bangalore-based Indian Institute of Science (iisc) have devised a new method to forecast the monsoon, that too eight months ahead of the rainfall season. The statistical method, developed by R N Iyengar and S T G Ravikanth, is much less complicated than the existing forecasting models, as …
