Daniel Swain and colleagues model how the frequency of these rapid, year - to - year transitions from extreme dry to wet conditions — which they dub «precipitation whiplash events» — may change in California's future as a consequence of man - made warming.

Warm oceans produced extensive evaporation and precipitation, which on the cold continents resulted in extreme snowfall rates that built up glaciers.

«We show that at the present - day warming of 0.85 °C about 18 % of the moderate daily precipitation extremes over land are attributable to the observed temperature increase since pre-industrial times, which in turn primarily results from human influence,» the research team said.

The first piece of Mildrexler and colleagues» effort was the creation of a forest vulnerability index that, in effect, relates climatic drivers of vulnerability, such as extreme temperature and low precipitation, directly to physiological stress factors, which reduce photosynthesis and deteriorate forest health.

Also, I'd like to see someone try to explain the extreme precipitation deficit which occurred during the Dust Bowl years in the Midwest and West.

The index, which evaluates extremes in temperature and precipitation, as well as landfalling tropical cyclones, was nearly twice the average value and second only to 1998.

Nevertheless, the IPCC AR5 presents an outlook of increasing extreme precipitation in tropical cyclones making landfall (p. 106, Table TS.2), which is relevant for the flooding connected to Harvey.

When it comes to extreme weather, we always take the opportunity to point back to the last definitive international scientific report on extreme weather and climate change, which found strong historic links for heat waves, coastal flooding and changes in precipitation along with weaker links for tornadoes and hurricanes.

We do know that there are trends in temperature extremes and precipitation extremes (which are backed solidly by physics in a warming climate), but for the other metrics we don't really see trends at all.

But all were extreme events, both in terms of precipitation rates and of cost, of the sort which we expect to become much more frequent given both theory and observed metrics such as precipitable water in the atmosphere.

-- Increases in intensity and frequency of heat waves and extreme precipitation events (a category in which it includes droughts, floods, hurricanes and major storms)

The photos allow Romps, a climate scientist who specializes in clouds, to measure how fast the clouds rise, which in turn can shed light on a wide range of areas, ranging from lightning rates to extreme precipitation to the ozone hole.

Key weather and climate drivers of health impacts include increasingly frequent, intense, and longer - lasting extreme heat, which worsens drought, wildfire, and air pollution risks; increasingly frequent extreme precipitation, intense storms, and changes in precipitation patterns that lead to drought and ecosystem changes (Ch.

The effects of weather extremes on human health have been well documented, particularly for increased heavy precipitation, which has contributed to increases in severe flooding events in certain regions.

Overall, however, scientists project an increase in precipitation in the Great Lakes region (with extreme events projected to contribute to this increase), which will contribute to maintenance of or an increase in Great Lakes water levels.

In the most absurd case of Pielke misdirection, Field accurately reports the SREX findings on extreme precipitation events, which Pielke Jr. purports is a misrepresentation because of something that report said about flood losses.

It allows to imagine conditions to which society may be vulnerable (e.g., a combination of extreme precipitation and a storm surge that hinders discharging the abundant water) but have never occurred yet in the historical record.

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.

Changed pattern and quantity of precipitation in concert with temperature extremes manifests itself in a number of catastrophic outcomes like drought, slides, snowmelts, floods, agricultural productivity loss, and upsurge in diseases which impact both the natural and the human systems [continue reading...]

Greater cropping systems diversity can also help mitigate risks associated with the impacts of global climate change, which will drive more extreme and variable weather events, not to mention sustained temperature and precipitation changes that will impact agricultural production.

A warmer atmosphere drives more extreme precipitation across all storm types, which in turn increases the the risk of flooding.

The increasingly extreme behavior of precipitation in California — which could very well occur without much of a change in California's overall average precipitation — may increase the risk of both drought and flood events in the state.

We further find that years with extreme geopotential heights in the climate models exhibit a Triple R - like regional maximum in the northeastern Pacific, and are associated with shifts in wind patterns and precipitation along the West Coast that are strongly reminiscent of those which occurred during 2013 - 2014.

The culprit behind much of the extreme heat in each case has been large, strong, and persistent areas of high pressure, which have set up shop over these high latitude locations, keeping cooler weather and precipitation at bay.

Extratropical cyclones (ETCs) often produce extreme hazardous weather conditions, such as high winds, blizzard conditions, heavy precipitation, and flooding, all of which can have detrimental socio - economic impacts.

The statistical analyses in these Hurricane Harvey studies focused on extreme precipitation in general, to which hurricanes contributed, but were not analyses of extreme rainfall only from hurricanes.

And that's not even counting average precipitation or orccurance of extreme events which are part of the climate but much more difficult to reconstruct.

These shifts can also alter the intensity distribution (e.g. wet areas getting wetter and dry areas drier (Held and Soden 2006)-RRB-, potentially leading to more extremes either directly (Portmann et al. 2009) or indirectly via teleconnections (Kenyon and Hegerl 2010), which would again lead to damages even in cases where changes in mean precipitation could be beneficial.

The SREX clearly found a major increase in heat waves and extreme precipitation events, and in order to adapt to these occurrences, the intensity and frequency of which is likely to increase, it would be essential to take in hand urgently certain low regrets measures.

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).
