The salutary influence of irrigation on human settlement, economy and political power in pre-modern southeast Asia

The tropical monsoon rhythm for over centuries obviously occasioned the development of water works which facilitated wet rice cultivation in pre-modern Southeast Asia. The small-scale water works, purely an outcome of local initiative which survived for many centuries and outlived the state, were developed in the dry zone of Irrawaddy …

ENSO control on the south Asian monsoon through the length of the rainy season

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 …

Climate and water resources of India

We attempt to synthesize available quantitative, precisely dated and high-resolution palaeorecords of the South Asian summer monsoon from different natural archives, highlighting their similarities and differences. We distinguish between the palaeorecords of monsoon winds and monsoon rainfall and underscore the importance of quantitative rainfall reconstruction using the amount effect in …

Weakening trend of the southwest monsoon current through peninsular India from 1950 to the present

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

Extreme weather events over India in the last 100 years

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 …

Atmospheric brown clouds: Impacts on South Asian climate and hydrological cycle

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 …

The Rs 500 crore forecasting machine

ERRATIC monsoons always make good news copy in India. It is the official weather forecasting agency, the India Meteorological Department (IMD), that bears the brunt of criticism. Sometimes justifiably so, for often its take on the southwest monsoon goes off the mark, as it happened in July this year. IMD …

Simple yet reliable?

Scientists at the Bangalore-based Indian Institute of Science (iisc) have put to test a simple yet innovative forecasting model, which uses past rainfall data to predict monsoon. The model, developed by R N Iyengar and S T G Raghukanth, has been used for the first time this year to forecast …

Forecast bright, foresight lacking

At a time when water levels in most of the country's reservoirs have plummeted below their 10-year average, the Union government still seems to be on the high it got from last year's monsoon-propelled 8 per cent-plus gdp growth. A normal monsoon has been predicted for this year, too; that …
