Sentences with phrase «of the aerosol particles formed»

The index of refraction and an average size of the aerosol particles formed are close to those characteristic of the natural stratospheric aerosol.

Not exact matches

A key giveaway that aerosols were behind the effect was that the lightning was most pronounced at times of the year when powerful atmospheric convection currents form that can carry the aerosol particles high into the sky (Geophysical Research Letters, doi.org/cc7b).

Such sulfuric acid aerosols are already responsible for the bulk of nacreous clouds that form in the polar stratosphere; added particles would just amp up the natural process (although it might also amp up damage the ozone layer).

There are few absolutes in life, but Will Cantrell - professor of physics at Michigan Technological University - says this is one: «Every cloud droplet in Earth's atmosphere formed on a preexisting aerosol particle.»

Additional aerosol mass composed of organosulfate and organonitrate chemicals can then form via nitrogen oxide - initiated oxidation of VOCs from natural vegetation (e.g., isoprene) in the presence of highly acidic ultrafine particles.

Ice nuclei, a type of aerosol particle in the atmosphere, form the ice crystals in mixed - phase clouds.

Incoming energy, which comes primarily from the sun, is turned into various forms of absorbed energy, depending on terrain and atmospheric conditions such as clouds and aerosol particles.

Airborne particles in the form of naturally occurring dusts and human - produced aerosols can serve as ice nuclei, sites around which water vapor condenses into clouds.

The organic aerosol particles that coat the toxic hitchhikers are wafted into the atmosphere through emissions from trees (like those that produce the smell of pine trees), and burning biomass and fossil fuel to form a semi-solid sap - like casing surrounding and protecting the particle's payload from breaking down in the atmosphere.

Coupling these new measurements with detailed cloud simulations that resolve the size distributions of aerosols and cloud particles, we found several lines of evidence indicating that most anvil crystals form on mid-tropospheric rather than boundary - layer aerosols.

«The results also show that ionisation of the atmosphere by cosmic rays accounts for nearly one - third of all particles formed, although small changes in cosmic rays over the solar cycle do not affect aerosols enough to influence today's polluted climate significantly.»

With regard to the actual content of the press release quoted, it isn't clear if the process they report on (aerosol particles, particularly organic chemicals, getting smaller over time) makes them better or worse at forming clouds and their other atmosphere cooling functions.

Recently it was suggested that the formation of new atmospheric aerosol particles is connected with the existence of thermodynamically stable 1 - to 2 - nm clusters, formed in the atmosphere by some nucleation mechanism.

Organic aerosols are emitted as primary aerosol particles or formed as secondary aerosol particles from condensation of organic gases considered semi-volatile or having low volatility.
