Eight killed and thousands of people affected in Sri Lanka floods
At least eight people were killed and nearly 200,000 people have been affected due to torrential rain resulting from the north-east monsoon in the country.

Millennial- and orbital-scale changes in the East Asian monsoon over the past 224,000 years
High-resolution speleothem records from China have provided insights into the factors that control the strength of the East Asian monsoon.

The rhythm of the rains
Deposits in a Chinese cave tell the story of the region 's climate stretching back more than 200,000 years, well past the last interglacial warm period

Fresh water influence on nutrient stoichiometry in a tropical estuary, southwest coast of India
Cochin backwaters, a micro tidal estuary, undergo a characteristic transformation from a river dominated system during summer monsoon to a tide-dominant system during pre-monsoon season. The present study observes that as the river flow weakens after monsoon, the flushing of the estuary

Resolving an atmospheric enigma
In 1971, meteorologists Roland Madden and Paul Julian studied weather data from near equatorial Pacific islands. To their surprise, tropospheric winds, pressure and rainfall oscillated with a period of about 40 to 50 days.

A Madden-Julian Oscillation event realistically simulated by a global cloud-resolving model
A Madden-Julian Oscillation (MJO) is a massive weather event consisting of deep convection coupled with atmospheric circulation, moving slowly eastward over the Indian and Pacific Oceans. Despite its enormous influence on many weather and climate systems worldwide, it has proven very difficult to simulate an MJO because of assumptions about cumulus clouds in global meteorological models.

Rainfall intensity characteristics at coastal and high altitude stations in Kerala
Rainfall intensities measured at a few stations in Kerala during 2001–2005 using a disdrometer were found to be in reasonable agreement with the total rainfall measured using a manual rain gauge. The temporal

Variability of climate change in India
In this article meteorological measurements in India are analysed showing marked trends of increasing temperature over the past quarter century, but significant variations in these trends during different seasons and over different regions of India. Marked differences between the variations in minimum temperatures in North and South India have been brought out.

Climate change scenarios for India
Climate change is predicted to impact India's natural resource base, including water resources, forestry and agriculture, through changes in precipitation, temperatures, monsoon timings, and extreme events.
