Sentences with phrase «atmospheric air currents»

These data are used in large - eddy simulation (LES) models, which simulate atmospheric air currents and cloud processes, to provide context and a self - consistent representation of the atmosphere surrounding the SGP.

As the growing snow crystal is tossed by the air currents within a cloud, it encounters areas with different atmospheric conditions.

«Current atmospheric models underestimate the dirtiness of Arctic air.»

Satellite images and atmospheric models such as these have helped Jaffe demonstrate how mercury and other emissions from China feed into a complex network of air currents that distribute pollutants across the globe.

In addition, EPA will likely have to establish national ambient air quality standards (NAAQS) for greenhouse gases set below current atmospheric levels.

If La Nina / El Nino can affect global air temperatures in a period of a few years, than other changes in ocean currents (driven by AGW) can affect global atmospheric heat content in a few years.

Since building such an apparatus is not within our current technical capabilities, we can not via experiment (at least this type of experiment) determine exactly what the sensitivity actually is across the atmospheric air column.

However, at some point in time, air capture conceivably could be a useful tool to mitigate emissions from distributed sources, and may even be deployed to reduce atmospheric concentrations of CO2 below current concentrations.

Sidorenko tells about the factors that affect Earth's rotation, both that short term variability is largely due to changes in the atmospheric air movements and ocean currents, and that the decades - long fluctuations have another source, speed of drift of the lithosphere.

• «-LSB-...] only atmospheric air movements, and -LSB-...] currents in the ocean -LSB-...] cause the Earth's rotation instabilities.

Part Four — discussion and results of a paper by Dessler et al using the latest AIRS and CERES data to calculate current atmospheric and water vapor feedback vs height and surface temperature

Measurement of CO2 concentration is always problematic; the «Standard Dry Air» SDA basis of measurement and comparison is at standard temperature and pressure which is a non-existent parameter; and as we are seeing, CO2 is not a well - mixed gas at all and will be defined by, amongst other variables, SH, or absolute humidity; SH can vary from 0 to 5 % by volume of atmosphere; as the SH increases, the absolute amount of other gases, including CO2, decreases; to say therefore that atmospheric concentrations of CO2 have remained stable and not been above 280ppm over the last 650my is fanciful; even if you assume past CO2 levels have not got above 280ppm the range of variation within that limit has been greater than the current increase;

In conclusion, the present atmospheric measurement network, current information on air - sea fluxes and current understanding of vertical atmospheric transport are not sufficient to allow full use of the potential of inverse modelling techniques to infer geographically detailed source - sink distributions of anthropogenic CO2.

In addition, the Endangerment Rule authorizes or obligates EPA to establish: (1) greenhouse gas emission standards for heavy trucks, marine vessels, aircraft, locomotives, and other non-road vehicles and engines; (2) greenhouse gas performance standards for potentially dozens of industrial source categories; and, (3) national ambient air quality standards (NAAQS) for greenhouse gases set below current atmospheric concentrations.

This is because of the North Atlantic Current and large - scale atmospheric circulation which transport warm water and air masses from lower latitudes northwards across the Atlantic and along the coast of Norway to Svalbard (Figure 1).

The power of hyperspectral sounding has been amply demonstrated by the NASA EOS Atmospheric Infrared Sounder (AIRS) flying on the Aqua mission in a 13:30 orbit19 in terms of improved retrieval uncertainty and a significant positive impact on forecast skill.20 Operational LEO atmospheric temperature and moisture sounding capability in the 2010 + time frame will be provided by two instrument pairs (three during the transition from the current system).

These OMITTED / POORLY Represented processes include the following: oceanic eddies, tides, fronts, buoyancy - driven coastal and boundary currents, cold halocline, dense water plumes and convection, double diffusion, surface / bottom mixed layer, sea ice — thickness distribution, concentration, deformation, drift and export, fast ice, snow cover, melt ponds and surface albedo, atmospheric loading, clouds and fronts, ice sheets / caps and mountain glaciers, permafrost, river runoff, and air — sea ice — land interactions and coupling.
