Sentences with phrase «relative changes in precipitation»

First, a bias correction algorithm, quantile delta mapping (QDM), that explicitly preserves relative changes in precipitation quantiles is presented.
Relative changes in precipitation (in percent) for the period 2090 — 2099, relative to 1980 — 1999.

Not exact matches

Rising temperatures and changing precipitation patterns will lead to relative changes in agricultural production, possibly spurring rural to urban migration, or migration across borders to seek more favorable conditions.
The water vapor feedback (a generally positive feedback)-- there is an roughly exponential increase in saturation water vapor pressure with increasing temperature, and the relative humidity (at a given vertical level) overall tends not to change a lot globally, though there will be different regional trends associated with shifting precipitation patterns.
2: Our Changing Climate, Key Message 5).2 Regional climate models (RCMs) using the same emissions scenario also project increased spring precipitation (9 % in 2041 - 2062 relative to 1979 - 2000) and decreased summer precipitation (by an average of about 8 % in 2041 - 2062 relative to 1979 - 2000) particularly in the southern portions of the Midwest.12 Increases in the frequency and intensity of extreme precipitation are projected across the entire region in both GCM and RCM simulations (Figure 18.6), and these increases are generally larger than the projected changes in average precipitation.12, 2
Model projections for precipitation changes are less certain than those for temperature.12, 2 Under a higher emissions scenario (A2), global climate models (GCMs) project average winter and spring precipitation by late this century (2071 - 2099) to increase 10 % to 20 % relative to 1971 - 2000, while changes in summer and fall are not expected to be larger than natural variations.
Bonfils, C.J.W., B.D. Santer, T.J. Phillips, K. Marvel, L.R. Leung, C. Doutriaux, and A. Capotondi, 2015: Relative contributions of mean - state shifts and ENSO - driven variability to precipitation changes in a warming climate.
Also the spatial structure of changes in precipitation linked to altered surface temperature by convection can be improved by using higher resolution model experiments, although the relative gain here is generally small (Di Luca et al, 2012).
With wNA forest loss, there are significant declines in both precipitation and temperature during the early growing season, however it is the change in the relative humidity that dominates the observed increase in VPD.
The first paper cited notes (caveating that observational uncertainties are considerable) that models do not match observed changes in subtropical relative humidity or in global precipitation.
The scatter diagrams described and presented on these pages depict projected changes in seasonal surface air temperature and precipitation for three 30 - year periods (2010 - 2039, 2040 - 2069 and 2070 - 2099) relative to the baseline period 1961 - 1990 in 32 sub-continental scale regions (see below).
''... report that «most trends exhibited no clear precipitation change,» noting that «global changes in precipitation over the Earth's land mass excluding Antarctica relative to 1961 - 90 were estimated to be: -1.2 ± 1.7, 2.6 ± 2.5 and -5.4 ± 8.1 percent per century for the periods 1850 - 2000, 1900 - 2000 and 1950 - 2000, respectively.»
Cannon, A.J., Sobie, S.R., Murdock, T.Q., (2015) Bias correction of simulated precipitation by quantile mapping: how well do methods preserve relative changes in quantiles and extremes?
Use as a baseline to which changes in the 21st century relative to the model baseline period are applied (add for temperature, multiply for precipitation).
PRUDENCE RCM outputs showed non-linear relationships between mean maximum temperature and indices of drought and heatwave (Good et al., 2006), while changes in maximum 1 - day and 5 - day precipitation amounts were systematically enhanced relative to changes in seasonal mean precipitation across many regions of Europe (Beniston et al., 2007).
