Black carbon in soot is the dominant absorber of visible solar radiation in the atmosphere. Anthropogenic sources of black carbon, although distributed globally, are most concentrated in the tropics where solar irradiance is highest. Black carbon is often transported over long distances, mixing with other aerosols along the way. The aerosol mix can form transcontinental plumes of atmospheric brown clouds, with vertical extents of 3 to 5 km.

Kalimpong: Six-hundred-and-forty households in and around Kalimpong have appealed to Prime Minister Manmohan Singh to save them from landslides, a threat that looms large in the hills during monsoon.

Sub-seasonal rainfall fluctuations, characterized as active and weak spells during the Indian monsoon season (June to September) is an important component of the variability of the Indian monsoon rainfall.

A meeting convened to discuss the preparedness of monsoon and to adopt preventive measures in future and action to be taken before the onset of monsoon was held at South Goa Collectorate building in M

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.

High-resolution speleothem records from China have provided insights into the factors that control the strength of the East Asian monsoon.

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

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

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 (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.
