So: The study finds a fingerprint of anthropogenic influences on large scale increase in precipitation extremes, with remaining uncertainties — namely that there is still a possibility that the widespread increase in heavy precipitation could be due to an unusual event of natural variability.The intensification of extreme rainfall is expected with warming, and there is a clear physical mechanism for it, but it is never possible to completely separate a signal of external forcing from climate variability — the separation will always be statistical in nature.

Changes in extreme precipitation projected by models, and thus the impacts of future changes in extreme precipitation, may be underestimated because models seem to underestimate the observed increase in heavy precipitation with warming.

This apparent inconsistency says little about the overall trend in the heaviest precipitation events, but a lot about the weaknesses of single - point measurements for detecting trends in extreme precipitation.

It is noteworthy that the influence of warmer temperatures and increased water vapour in the atmosphere (Section 2.5.3) are not independent events, and are likely to be jointly related to increases in heavy and extreme precipitation events.

Of the types of extremes that battered the country this year, only certain large - scale phenomena among them — such as heat waves, droughts and heavy precipitation — have links to climate change.

A reduced snow cover extent in the mountainous West changes the peak river flow, as does timing of increases in heavy and extreme precipitation reported in the United States, which is best reflected during the warm season.

A summary of the report released in November predicts an increase in certain types of extreme weather, including daily high temperatures, heat waves, heavy precipitation and droughts, in some places.

Since large portions of the mid - and high latitude land areas have had increasing precipitation during the last half the 20th century, the question arises as to how much of this area is affected by increases in heavy and extreme precipitation rates.

Documented long - term climate changes include changes in Arctic temperatures and ice, widespread changes in precipitation amounts, ocean salinity, wind patterns and extreme weather including droughts, heavy precipitation, heat waves and the intensity of tropical cyclones.

A warmer atmosphere holds more moisture, so precipitation can be heavier and cause more extreme flooding.

A set of long, nearly complete daily precipitation series for Alaska spanning the latter half of the 20th century has been analyzed for seasonal relationships between variations in mean, heavy, and extreme precipitation and large - scale atmospheric circulation variations at interannual, decadal, and secular timescales.

Changes in some types of extreme events have already been observed, for example, increases in the frequency and intensity of heat waves and heavy precipitation events (see FAQ 3.3).

Analysis of extreme precipitation simulated by climate models has included the daily variability of anomalous precipitation (Zwiers and Kharin, 1998; McGuffie et al., 1999; Kharin and Zwiers, 2000), patterns of heavy rainfall (Bhaskran and Mitchell, 1998; Zhao et al., 2000b), as well as wet and dry spells (Thorncroft and Rowell, 1998; McGuffie et al., 1999).

In summary, in contrast with the simulations of extreme temperature by climate models, extreme precipitation is difficult to reproduce, especially for the intensities and patterns of heavy rainfall which are heavily affected by the local scale (see Chapter 10).

Many impacts of climate change will be realised as the result of a change in the frequency of occurrence of extreme weather events such as windstorms, tornados, hail, heatwaves, gales, heavy precipitation or extreme temperatures over a few hours to several days.
