Sentences with phrase «atmospheric dust»
"Atmospheric dust" refers to tiny particles of solid or liquid matter that are suspended in the air. These particles can come from various sources, such as dust storms, volcanic eruptions, pollution, or even natural processes like the breaking down of rocks. They can affect air quality, visibility, and even have important roles in climate and weather patterns. Full definition
One factor is the decline in atmospheric dust over the last 50 years, which is related to climate change.

Results: Tiny bits of atmospheric dust and particles called aerosols may play a big role in global climate change, but just how big a role is not well understood.
For years most scientists have attributed this ominous event to atmospheric dust following a volcanic eruption.
Figure 1 shows the increase in model atmospheric dust when this source is added, relative to a simulation without the added dust source.
This temperature contrast makes for more high intensity storms, which leads to more atmospheric dust and sea salts, which reflects more sunlight back into space and cools the earth further.
Exposed soil caused increased atmospheric dust loads (Nicholson, 2000, 2001).
In observational data, we find striking and globally coherent increases of atmospheric dust concentrations and deposition during the coldest phases of glacial − interglacial climate cycles.
«Maybe others might be inspired and look at the geochemistry or atmospheric chemistry implications, such as how these water cluster structures on atmospheric dust nanoparticles could affect cloud formation, rain and acid rain,» Mavrikakis says.
Even if we assume that the rate of scavenging and other removal processes for atmospheric dust particles remains constant, it is still difficult to predict the rate at which global background opacity of the atmosphere will increase with increasing particulate injection by human activities.

Yoav Yair of the Open University in Ra'anana, Israel, and colleagues spent more than a year analysing the video, which was originally taken to study atmospheric dust.
Roughly half the mercury contamination in the United States comes from Asia; much of it may arrive aboard particles in atmospheric dust clouds.
Low tack double - sided adhesive tape (the adhesive on the tape will attract atmospheric dust and fibres so it may be necessary to place a fresh strip over the original on a daily basis if the cat is persistent.)
From the almost physical presence of the waterfalls, now the paint disintegrates into atmospheric dust, into impalpable luminous presences, in an atomization of vision... the loss of the image's physicality is replaced by the paint's elusiveness, which recalls the last paintings of Mark Rothko for the ecumenical chapel in Houston.»
Figure 1, at left: Ensemble mean differences in total atmospheric dust loading, g / m2, Experiment 3 (SST+D ust) minus Experiment 2 (SST only).

This is a response to higher iron availability in glacials, linked to higher atmospheric dust input to the ocean.
This increased availability of iron occurs in connection to increased atmospheric dust transport during glacials, or (at a seasonal scale) during sea ice retreat during spring / summer.
According to the study's authors, quantifying the amount and sources of atmospheric dust concentrations is also important to improve future climate change predictions.
It has to be pushed in one direction (warming) or another (cooling) by positive forcing or feedbacks (e.g. brighter sun, addition of greenhouse gases, lower albedo) or negative forcing / feedbacks (e.g. dimmer sun, drawdown of greenhouse gases, increased atmospheric dust, greater ice cover, increased volcanic activity).]
But although some evidence points to past water oceans on Mars, only small amounts of carbonates have been found there — in Martian meteorites that landed on Earth and in atmospheric dust and bright soils on the planet.
Combining the two instruments» data will help isolate the confounding effects of atmospheric dust.
Hazy conditions, atmospheric dust, and high humidity contribute to this atmospheric attenuation.
Orbital parameters are changing, as is atmospheric dust, and glaciers have a dynamics of their own which can lead to short - term decorrelations of temperature and CO2 over periods of a few thousand years.
Claquin et al's model - derived findings show a change in tropical atmospheric forcing of «-- 2.2 to — 3.2 W m — 2» between PI and LGM earth, due to the increased albedo of atmospheric dust.
The faster - acting ones are atmospheric dust; changes in ocean circulation; feedbacks due to water vapour, clouds, and snow; and the concentrations of greenhouse gases.Variations in the earth's orbital movements around the sun create very slow climate cycles.
To test the effect of atmospheric dust, we ran the GISS climate model with observed SSTs for 1932 - 1939, with and without the presence of a dust source over the Great Plains.
Most of the GMT drop has been attributed to radiative forcing decreases from increased albedo due to equatorward ice extension and from decreased greenhouse gas concentrations; vegetation and atmospheric dust are thought to play secondary roles (20, 21).
Wind erosion has many harmful effects: the land from which the dust is blown loses nutrients and water - holding capacity and atmospheric dust can affect human health.
Comment: The observed rapid climate change events, «RCCEs» are becoming stronger based on a significant increase in atmospheric dust in both the Antarctic and Greenland ice cores during the last glacial period, as compared to past glacial periods.
