India climate: What do drowning rhinos and drought tell us?

A river, swollen by raging monsoon floodwaters, had torn down a bridge on the main road between Mumbai and Goa. More than 30 people are thought to have died when the great stone structure crashed into the torrent, taking with it two buses and a number of cars. Some of the bodies were swept more than 60 miles downriver in two days. Image copyright AP We produced a short news report.

In the heart-wrenchingly brutal calculus of the newsroom, this isn't a major story. India, indeed the whole South Asia region, has been riding a rollercoaster of extreme weather. The summer monsoon is the most productive rain system in the world, and this year the region is experiencing a strong one. Though what really caught people's interest was the three baby rhinos rescued from the waters in the north Indian state of Assam.

Flooding Flooding is caused by: a large amount of persistent rain rapid thawing of snow a storm surge a combination of high tides and high river levels Storm surges Storm surges are caused by strong winds and low air pressure. Storm surges create large waves. The greatest storm surge on record for the North Sea as a whole occurred on 31 January and 1 February 1953. Tropical cyclones A tropical cyclone is a low pressure system over tropical or sub-tropical waters, with convection (i.e. thunderstorm activity) and winds at low levels, circulating either anti-clockwise (in the northern hemisphere) or clockwise (in the southern hemisphere). Thunderstorms Most thunderstorms are associated with towering clouds known as cumulonimbus. While air is rising it is said to be unstable. For example, on a summer's day, the land is warmed by the sun, and as the air just above becomes warmer it starts to rise. Lightning.
