The new study confirms that so - called «starving glaciers» in dry, high - altitude environments are indeed
controlled by precipitation.
While CO2 can stay in the atmosphere for hundreds of years, black carbon is typically washed out
by precipitation within days or weeks.
Removing
water by precipitation will lower the pressure in that column but only as this process continues, and it will change the pH, which could have significant effects.
The concentration of in - situ antibody - AChR complexes was determined
by precipitation with goat anti-rat serum in the presence of normal rat serum.
Blueberries are thought to have
formed by the precipitation of iron - bearing minerals when groundwater rose up through layers of sediment.
However, instead of water - filled oceans and seas, they're composed of methane and ethane and are
replenished by precipitation from hydrocarbon - filled clouds.
Sedimentary rock is one of the three main rock groups (along with igneous and metamorphic rocks) and is formed in four main ways: by the deposition of the weathered remains of other rocks (known as «clastic» sedimentary rocks); by the accumulation and the consolidation of sediments; by the deposition of the results of biogenic activity; and
by precipitation from solution.
Mueller, B. and S. Seneviratne (2012), Hot days
induced by precipitation deficits at the global scale, 12398 — 12403, PNAS, July 31,, vol.
This is exemplified
by precipitation levels in the Black River basin, a tributary of the Min River in Sichuan province, where since the 1970s, precipitation has declined by 8 to 20 percent during the months of July and August.5
Erosion of river deltas is also
influenced by precipitation patterns inland which change patterns of freshwater input, run - off and sediment delivery from upstream.
Methane hydrates are believed to form by migration of gas from depth along geological faults,
followed by precipitation, or crystallization, on contact of the rising gas stream with cold sea water.
In this phase solid, organic and inorganic matter as well as heavy metals are
removed by precipitation and gravity; and a sludge settles at the bottom of the reactor.
As the effects of temperature anomalies on the PDSI are small compared to precipitation anomalies (Guttman, 1991), the PDSI is largely controlled
by precipitation changes.
If the casein is removed from skim
milk by a precipitation method, such as the addition of mineral acid, a group of proteins remains in solution that are called milk serum proteins.
The lakes they examined are so - called closed - basin lakes, which have rivers feeding into them, but not draining them, meaning that changes in lake levels are governed
solely by precipitation and evaporation.
Wildfires whipping across a landscape can burn away ground cover and vegetation, leaving soils exposed and easily
erodible by precipitation.
These anvil cloud tops, which form from moisture not
harvested by precipitation in tall, convective tower clouds, operate as Earth's thermal blanket and therefore are an important component of the climate system.
The reflectivity effect can be almost ten times more important than the effect of mass directly
added by precipitation [Moelg and Hardy, 2004].
The aspect of the paper that has attracted the most attention is the claim that the retreat of the Kilimanjaro summit glaciers can be
explained by precipitation reduction, without any compelling need to invoke a warming trend in local air temperature.
Climate studies only considered temperature, usually and incorrectly attributing changes
caused by precipitation to temperature.
Finally, they tracked radiocarbon, which is also carried
downward by precipitation, as a representative of young, easily altered, and mobile forms of carbon that stimulate methane production.
The long - term climate change across the continental U.S. as
represented by the precipitation, hurricane landfall events and drought are much more difficult to discern from their respective fitted trends (objectively, they are rather climatically insignificant overall).
On Earth, atmospheric CO2 is
absorbed by precipitation --- by rain — and forms a very weak solution of carbonic acid, a very mild form of acid rain.
Because of the first of these reasons, were we to abruptly halt all emissions now, the sulfate aerosols would rapidly be removed from the atmosphere
by precipitation whereas the CO2 concentration would remain elevated, and so there would be a significant further warming influence just as a result of past emissions; this warming would lead to the quite significant global warming that Lindzen mentions.
Inter-annual runoff variation in the Himalayan glacier catchment is driven
more by precipitation than by the mass balance change of glaciers (36);
And when the last three water years are evaluated (October 1, 2011 to September 30, 2014), we see that the current drought (measured
only by precipitation levels) is by far the most severe in the entire instrumental record (Figure 3).
However, at latitudes poleward of 40 ° in winter, positive correlations dominate as the water - holding capacity of the atmosphere limits precipitation amounts in cold conditions and warm air advection in cyclonic storms is
accompanied by precipitation.
