Sentences with phrase «only by precipitation»

However, it has been known since the earliest general circulation simulations by Manabe that as the Earth warms in response to increasing CO2, the precipitation increases much more slowly than Clausius - Clapeyron would suggest — typically only 2 - 3 % per degree of warming.
My experience with extremes and detection and attribution of an anthropogenic signal in those is that only by averaging the behavior of extremes (both temperature extremes and precipitation extremes) over large geographical areas (continental or barely sub-continental) we have been able to see something outside of natural variability.
Climate studies only considered temperature, usually and incorrectly attributing changes caused by precipitation to temperature.
They found that during the dry and transitional phases, contemporary precipitation penetrated only 1 meter into the peat, but by the onset of the moist phase it had flushed the top 2 meters.
On average in the United States, the amount of rain falling during the heaviest 1 percent of rainstorms has increased nearly 20 percent during the past 50 years — almost three times the rate of increase in total precipitation.4, 5 The Midwest saw an even larger average increase of 31 percent, surpassed only by the Northeast (at 67 percent).4 Scientists attribute the rise in heavy precipitation to climate change that has already occurred over the past half - century.6
As for how this could be — and in light of the findings of the references listed above — Rankl et al. reasoned that «considering increasing precipitation in winter and decreasing summer mean and minimum temperatures across the upper Indus Basin since the 1960s,» plus the «short response times of small glaciers,» it is only logical to conclude that these facts «suggest a shift from negative to balanced or positive mass budgets in the 1980s or 1990s or even earlier, induced by changing climatic conditions since the 1960s.»
This is one of the more challenging aspects of modeling of the climate system because precipitation involves not only large - scale processes that are well - resolved by models but also small - scale process, such as convection, that must be parameterized in the current generation of global and regional climate models.
Because the model only describes the rainy season and does not capture the annual monsoon cycle, abrupt transitions in the bistable regime can only be interpreted intraseasonally, e.g., a month of heavy rain followed by a month of extraordinarily weak precipitation.
Declines in Colorado River reservoirs can only partly be blamed by a lack of precipitation.
A rise in precipitation and a fall in snowpack can only be accounted for by greater melting or rainfall during the winter.
By August 1990, Lewis Glacier had disappeared, runoff from the former glacier basin was 0.04 x 106 m3, only 27 % of the glaciated flow, despite the presence of some relict glacier ice, and that total monthly precipitation was the same.
Freezing level elevations are incorporated by including only May and October precipitation occuring when Stevens Pass temperature is below 7oC as accumulation season precipitation.
It is true that CDR might well be better at this remedial task — by reducing GHG concentrations it not only reduces temperatures, but also ocean acidification, and better restores pre-existing precipitation regimes.
Although the current study is limited by the fact that the authors looked only at runoff and held other variables such as land cover constant, the results could be relevant to other regions that are likely to experience precipitation increases in a warming world.
B classification is the only one initially determined by annual precipitation.
«The authors demonstrate that model estimates of climate sensitivity can be strongly affected by the manner through which cumulus cloud condensate is converted into precipitation in a model's convection parameterization, processes that are only crudely accounted for in GCMs.
The intensity of precipitation is of interest, but even that doesn't say a lot about total volume of precipitation given that rainfall is, by its nature, is not measured by area, it is only measured at a point — or several points — all of which will have different results.
Removing water by precipitation will lower the pressure in that column but only as this process continues.
[3] October through December 2016 were very wet months in northern California (with precipitation totals about 170 percent of normal by 1 January 2017), but because several of the storms were warm rainfall, snow pack in California by 1 January was only 64 percent of normal.

b Trends surface temperature from the GOGA CAM3 simulations (background colorscale; air temperature over sea ice and SST elsewhere) along with the Z850 trend produced by the model simulations (black contours; negative dashed and positive solid; interval of 3 m / decade) and the simulated convective precipitation trends (positive green contours, negative red contours, contoured at − 0.7, − 0.3, − 0.1, 0.1, 0.3, and 0.7 mm / day / decade, shown only for 45 ° S — 45 ° N. (c) As in (b) but for the TOGA CAM3 simulations.
Dry climates are the only climates classified by precipitation.
Thus, glaciers in the steep Himalayas are not only affected by temperature and precipitation, but also by debris coverage, and have no uniform and less predictable response, explained the authors.
Tropical precipitation need increase by only a couple percent to achieve that effect.
All precipitation data in cold climates are only approximate, because snow is driven by wind and it is hard to discriminate between falling and blowing snow.
Well, speaking only of Queensland, Chapter 11 of AR4 WG1, Regional Climate Projections, was very careful to make no specific projections for Australia and Queensland until 2080 - 2099 -LRB-(fig. 11.17), by when only those under 30 now are likely to be alive to verify whether its actual prediction of NO FLOODS in the Western Pacific proved correct: ALL 21 of the models deployed to make that prediction actually forecast precipitation at LESS than the average in 1980 - 1999.
Lower case a-h refer to how the literature was addressed in terms of up / downscaling (a — clearly defined global impact for a specific ΔT against a specific baseline, upscaling not necessary; b — clearly defined regional impact at a specific regional ΔT where no GCM used; c — clearly defined regional impact as a result of specific GCM scenarios but study only used the regional ΔT; d — as c but impacts also the result of regional precipitation changes; e — as b but impacts also the result of regional precipitation change; f — regional temperature change is off - scale for upscaling with available GCM patterns to 2100, in which case upscaling is, where possible, approximated by using Figures 10.5 and 10.8 from Meehl et al., 2007; g — studies which estimate the range of possible outcomes in a given location or region considering a multi-model ensemble linked to a global temperature change.
Research data show that climate change caused by human behavior is fueling more frequent and intense weather, such as extreme precipitation and heat waves — so it's only natural to wonder if this applies to tornadoes, too.
This leaves only the surface evaporative cooling, which is balanced by global precipitation, as the term to accommodate such an increase.
