"Extreme rainfall" refers to a very heavy and intense amount of rain that falls in a short period of time. It means there is a lot of rain coming down at once, causing potentially severe flooding and other related problems.
Full definition
A warmer atmosphere can hold more moisture, for example, which raises the risk of
extreme rainfall events and the flooding they cause.

of extreme rainfall in the southern part of the country by about 25 per cent.
Scientists show that devastating increases
in extreme rainfall over the last 30 years fit in with global temperature rise caused by greenhouse gases.

duration extreme rainfall and atmospheric temperature.
In presentations we have given and in the papers in prep right now, we call into question the traditional ways in which we
estimate extreme rainfall frequency, probability and intensity.
The water holding capacity of the atmosphere increases by about 7 % per °C of warming, which in turn raises the expectation of more
intense extreme rainfall events.

in extreme rainfall risks by the end of the century.
Already, there's evidence that
extreme rainfall events are on the rise and are expected to worsen in the coming years.

more extreme rainfall.

extreme rainfall from a storm like Desmond in the region by about 40 percent, with a full range of between 5 and 80 percent.

extreme rainfall on the west coast throughout the year and in winter rainfall elsewhere.
Climate change could mean England is in for more
such extreme rainfall events because of increasing moisture in the atmosphere and changes in atmospheric weather patterns, a new study detailed online Monday in the journal Nature Climate Change finds.

extreme rainfall cause devastating flooding in Pakistan, killing hundreds of people and prompting an outbreak of cholera.
[37] These changes can dramatically amplify extreme weather events, such
as extreme rainfall, during the summer.
But then when the speaker got to the final conclusion, it was essentially a tiny correlation
between extreme rainfall events in a few very particular places with particular large scale atmospheric flows upstream.
[7][8] A warmer atmosphere holds more water vapor, feeding more precipitation into all storms including hurricanes, significantly
amplifying extreme rainfall and increasing the risk of flooding.
In concert with the results for increased extremes of intense precipitation, even if the wind strength of storms in a future climate did not change, there would be an increase in
extreme rainfall intensity.
Especially to the west and east the Australian coastal waters have a rather large (1 - 2C) positive temperature anomaly, favouring the formation of depressions that recently even
brought extreme rainfalls in the bone dry inland deserts of the Northern Territory and South Australia.
«There is overwhelming scientific evidence that the characteristics of
extreme rainfall under climate change are going to be different,» said Praveen Kumar, a professor of civil and environmental engineering (CEE) at Illinois and project leader on the study.
While atmospheric rivers vary in size and shape, those containing large amounts of water vapor, strong winds, and that stall over watersheds vulnerable to flooding, can
create extreme rainfall and floods.
December 2011: Two days of
extreme rainfall deluge New Zealand's Southern Island, producing landslides in what scientists call a 1 - in -500-year-event.
This December is around 5C warmer than normal and physics tells us that 24
hour extreme rainfall increases by 7 % per degree.
Other parts of South England and Wales also
experienced extreme rainfall amounts during these three months, and as a consequence, large areas were flooded, some more than once during that period.
Science has attributed heavy rain to climate change for decades, but now we can analyze the role of climate change in
individual extreme rainfall events.

term extreme rainfall events — e.g. during single days — have become more common recently.
A warmer ocean and the air above were able to inject greater quantities of moisture into the storm leading to intensification of
already extreme rainfall.

frequent extreme rainfall events.
