Extreme rainfall events today pose a serious threat to many populated and urbanized areas worldwide; an accurate estimate of frequency and distribution of these events can significantly aid policy planning and observation system design. We report here a first-ever high-resolution (10 KM) analysis of heavy rainfall episodes (defined as 24-hour rainfall exceeding 250 mm) over the Indian region.

Some teleconnections studies between the monsoon rainfall over four meteorological subdivisions namely, plains of west U.P., East U.P., Bihar Plains and Gangetic West Bengal, thus constituting an area of U.P., adjoining Bihar and West Bengal and different thickness anomaly and geopotential heights over several levels in the troposphere over India have been carried out to find some useful predictive parameters for the long range prediction of monsoon rainfall.

ON September 22, around 50,000 people gathered at Kharo Chaan, 150 km southeast of Karachi in Pakistan, for quite an unprecedented festival

Time was when climate change was a debate among scientists. Now, economists are looking at its costs. There is a warning or two for India. It has to do with the monsoon and the glaciers that feed Himalayan rivers. While the monsoon's behaviour is ch

Monsoon s changing intensity and course

Against a backdrop of rising global surface temperature, the stability of the Indian monsoon rainfall over the past century has been a puzzle.

monsoon distribution in the country is significantly influenced by irrigated agriculture. Scientists are now trying to figure out how vegetation and atmosphere interact and how it affects the

THE total seasonal rainfall during the year's southwest monsoon (June 1 to September 30) for the country as a whole was 99 per cent of its long-period average (LPA), which, being within plus or minus 10 per cent of the LPA, can be termed as a `normal' monsoon.

The skewed pattern of rainfall experienced across the country during this year's monsoon appears to be an anomaly.
