Warming from 1.5℃ to 2ºC will increase extreme precipitation events across Asia especially over East and South Asia  . In East and Central Asia, under 1.5℃ warming, extreme 1- and 5-d precipitation will increase by 28 and 15% relative to 1971-2000 . In China's urban agglomerations, an increase in global warming from 1.5℃ to 2ºC is likely to increase the intensity of total precipitation of very wet days 1.8 times and double maximum 5-d precipitation . Extreme rainfall has direct and increasing consequences on urban flooding risk , which is further exacerbated by urbanisation trends that reduce permeability, divert water flow and disrupt watersheds .
