precipitation, but locally, and at higher elevations within the mountains, this value can
increase to
greater than 20 inches (50.8 cm).
I'm not sure whether this is because it's thought that the
increase due to
greater precipitation is
greater than the
increase due to melt or whether because there is more confidence in an
increase in
precipitation [and its magnitude] compared to that of melting permafrost.
Indeed, snowfall is often predicted to
increase in many regions in response to anthropogenic climate change, since warmer air, all other things being equal, holds more moisture, and therefore, the potential for
greater amounts of
precipitation whatever form that
precipitation takes.
This might have some relevance regarding Hadley projections of
greater harvests in India and China with CO2 fertilization and
increased precipitation in those areas...
This forest, too, is not adapted to fire, and when
increased heat causes rapid evaporation - even with similar
precipitation - our
greatest biological treasure and one of our largest carbon sinks will go up in a giant ball of flame.
The
increased precipitation toward the end of the Pleistocene was marked by a vast proliferation of pluvial lakes in the
Great Basin of western North America, notably Lake Bonneville and Lake Lahontan (enormous ancestors of present - day
Great Salt Lake and Pyramid Lake).
For the entire Northern Hemisphere, there is evidence of an
increase in both storm frequency and intensity during the cold season since 1950,1 with storm tracks having shifted slightly towards the poles.2, 3 Extremely heavy snowstorms
increased in number during the last century in northern and eastern parts of the United States, but have been less frequent since 2000.11,15 Total seasonal snowfall has generally decreased in southern and some western areas, 16
increased in the northern
Great Plains and
Great Lakes region, 16,17 and not changed in other areas, such as the Sierra Nevada, although snow is melting earlier in the year and more
precipitation is falling as rain versus snow.18 Very snowy winters have generally been decreasing in frequency in most regions over the last 10 to 20 years, although the Northeast has been seeing a normal number of such winters.19 Heavier - than - normal snowfalls recently observed in the Midwest and Northeast U.S. in some years, with little snow in other years, are consistent with indications of
increased blocking (a large scale pressure pattern with little or no movement) of the wintertime circulation of the Northern Hemisphere.5 However, conclusions about trends in blocking have been found to depend on the method of analysis, 6 so the assessment and attribution of trends in blocking remains an active research area.
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.
Risks of waterborne illness and beach closures resulting from changes in the magnitude of recent
precipitation (within the past 24 hours) and in lake temperature are expected to
increase in the
Great Lakes region due to projected climate change.97, 98,99,100
A declining ratio indicates that
greater percentages of
precipitation occur as rain instead of snow and / or that melt of winter snowpack is
increasing.
Following the seasonal evolution of the
precipitation climatology,
increased precipitation extremes shift from the Central
Great Plains in early summer to the Southwest in late summer.
The further south the cold air pushes the
greater the temperature contrast but also the potential for
increased precipitation.
Even where
increases are projected, there can be short - term shortages due to more variable streamflow (because of
greater variability of
precipitation), and seasonal reductions of water supply due to reduced snow and ice storage.
The
greater increases in erosion in the GGa1 scenario was attributed to
greater variability in monthly
precipitation and an
increased frequency of large storms in the model simulation.
greater pollutant loads due to
increased infiltration rates to aquifers or higher runoff to surface waters (as result of high
precipitation),
The models are in better agreement when projecting changes in hurricane
precipitation — almost all existing studies project
greater rainfall rates in hurricanes in a warmer climate, with projected
increases of about 20 % averaged near the center of hurricanes.
According to the National Climate Assessment, average rainfall during heavy
precipitation events across the Northeast, Midwest and
Great Plains has
increased by 30 percent since 1991.
I do see mounting evidence that
increasing SSTs can cause more intense hurricanes (more wind,
greater precipitation).
Elevated CO2 is projected to facilitate forest expansion and
greater carbon storage in California if
precipitation increases (Bachelet et al., 2001).
Along with the risk of drying, there is an
increased chance of intense
precipitation and flooding due to the
greater water - holding capacity of a warmer atmosphere.
Which is a bit strange considering a report from the European Environment Agency showing that temperatures in the Alps are
increasing a twice rate of the global average with more droughts and
greater seasonal variability in
precipitation forecast.
The FLOR model has been used extensively to understand predictability, change and mechanisms of tropical cyclones (Vecchi et al. 2014), Arctic sea ice (Msadek et al. 2014),
precipitation and temperature over land (Jia et al. 2015), drought (Delworth et al., 2015), extratropical storms (Yang et al. 2015), the
Great Plains Low Level Jet (Krishnamurthy et al. 2015), and the global response to
increasing greenhouse gases (Winton et al. 2014).
The differences are very small over most regions (less than ± 5 %), except for a small area of the equatorial Pacific Ocean, where the non-high-end models project an
increase in
precipitation that is about 50 per cent
greater than in the high - end models.
[A] nthropogenic climate change is expected to lead to a
greater incidence of high - intensity hurricanes, which together with rising sea level, will produce
increased risk of storm surge flooding, while hurricanes are projected to produce substantially more
precipitation as the atmosphere and oceans warm.
