Not exact matches

Climatic variability like precipitation changes or increase in extreme events such as storms and tropical cyclones is known to significantly modify the Earth's surface.

What goes up, must come down and, more and more, that water vapor is coming down in extreme precipitation events — defined in North America as more than 100 millimeters of rainfall (or the equivalent in snow or freezing rain) falling in 24 hours — according to new research also published February 17 in Nature that examines such events in the Northern Hemisphere.

The 2014 National Climate Assessment predicted that many U.S. communities will see extreme precipitation events more often as global temperatures rise.

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.

Also, as discussed below, extreme precipitation and drought events occurred across the world.

However, combined measuring stations around the world suggest there has been a global trend towards more frequent and intense hot extremes since the 1950s, as well as more heavy precipitation events.

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.

Heat waves, extreme precipitation events and flooding or extreme droughts, are also what actually cause climate damage — for instance lower agricultural productivity (as during the extremely hot 2003 summer in Western Europe) or biodiversity decline at ecosystem levels ranging from aquatic desert systems to entire rainforest biomes.

Whether climate change is expressed as a rise in temperatures, or as changing precipitation patterns — it is at the extreme edges of the graph that the frequency of weather events suddenly multiplies dramatically.

Maine could also see two to three times more extreme precipitation events, defined as four inches over 48 hours, said Wake.

More accurate and reliable precipitation data would be invaluable, not only for the study of climate trends and variability, but also as inputs to hydrological and ecological models and for model validation, characterization of extreme events, and flood and drought forecasting.

Output from global circulation models indicates that climate variability will continue to be an important characteristic of the region in the future [52], but that climate change may increase the risk of extreme climatic events such as multi-decade droughts and extreme winter precipitation [53], [54].

The report, written by 220 experts from 62 countries, finds that climate change has already contributed to changes in extreme events — such as heat waves, high temperatures, and heavy precipitation — in many regions over the past 50 years.

One of the most likely byproducts of global warming is more extreme precipitation events, as warmer temperatures can hold more water vapor in the atmosphere.

It is instructive to compare these numbers with those characteristic of a set of the years during 1979 — 2012 with no or only one major regional extreme event (in terms of land surface temperature and land precipitation anomalies) in the NH midlatitudes, from late April / early May to late September / early October, as reported yearly since 1993 in the World Meteorological Organization statements on the status of the global climate (see also ref.

It could be a simple event such as extreme precipitation or a tropical cyclone or a more complex sequence of a late onset of the monsoon coupled with prolonged dry spells within the rainy season.

Both also depend on aging infrastructure that has already been stressed by climate hazards including heat waves, as well as coastal and riverine flooding due to a combination of sea level rise, storm surge, and extreme precipitation events.

«[Researchers] have looked at changes to climate extremes, such as heatwaves, extreme precipitation events, cold nights.

Changes in temperature and precipitation patterns increase the frequency, duration, and intensity of other extreme weather events, such as floods, droughts, heat waves, and tornadoes.

More extreme precipitation events (with 3 - hour duration) so intense than in the past they would be exceeded on average only once every 10 years are projected to occur on average three times as often in future in Metro Vancouver and about three and a half times as often in future in CRD.

The projections also indicate an increase in the basin - averaged precipitation and an increase in the frequency of extreme precipitation events over the region as a whole.

Changing climatic variables relevant to the function and distribution of plants include increasing CO2 concentrations, increasing global temperatures, altered precipitation patterns, and changes in the pattern of «extreme» weather events such as cyclones, fires or storms.

Whilst the extent of climate change is often expressed in a single figure — global temperature — the effects of climate change (such as temperature, precipitation and the frequency of extreme weather events) will vary greatly from place to place.

Ecological surprises include rapid and abrupt changes in temperature and precipitation, leading to an increase in extreme events such as floods, fires and landslides, increases in eutrophication, invasion by alien species, or rapid and sudden increases in disease (Carpenter et al., 2005).

In general, the majority of all precipitation occurs as isolated 1 - day events, while most extreme precipitation occurs over a period of several hours embedded within 2 - 5 day events.

Nature paper As a consequence, a 25 % to 100 % increase in extreme dry - to - wet precipitation events is projected, despite only modest changes in mean precipitation.

The hope in California is that the large amounts of precipitation usually associated with extreme El Niño events would lessen the impacts of the state's multi-year drought by partly refilling reservoirs and groundwater, even as scientists caution that this might not happen to the degree needed to alter the present situation.

In the Pacific and Yukon Region of Canada, the extreme precipitation phenomenon known as an «atmospheric river» is one such event that has drawn the attention of climatologists, forecasters, emergency responders and policy advisors.

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.
