Sentences with phrase «small aerosols»

Small aerosols refer to tiny particles or droplets suspended in the air, such as dust, smoke, or mist. Full definition
* Yellow areas show where large and small aerosol particles are mixing.
Increasing evidence of small aerosol forcing supports the importance of internal variability in explaining inter hemispheric differences in temperature variability.
Avoid smaller aerosol - style extinguishers (they look like cans of hairspray), as they require you to get too close for comfort to the fire.
Cosmic rays interacting with the Earth's atmosphere producing ions that helps turn small aerosols into cloud condensation nuclei — seeds on which liquid water droplets form to make clouds.
It has until now been assumed that additional small aerosols would not grow and become cloud condensation nuclei, since no mechanism was known to achieve this.
The suggested hypothesis, is that in regions devoid of dust (e.g., over the large ocean basins), the formation of cloud condensation nuclei takes place from the growth of small aerosol clusters, and that the formation of the latter is governed by the availability of charge, such that charged aerosol clusters are more stable and can grow while neutral clusters can more easily break apart.
The Southern Hemisphere net positive RF very likely exceeds that in Northern Hemisphere because of smaller aerosol contributions in the Southern Hemisphere.
When there are a lot of very small aerosols around (i.e. after a nucleation event), they can also coagulate together.
Not all aerosols form clouds, Kirkby said, so it remains to be seen whether the very small aerosols he and his team created in the lab would grow large enough to seed clouds in the atmosphere.
The small aerosols need to grow nearly a million times in mass in order to have an effect on clouds.
The new results reveal, both theoretically and experimentally, how interactions between ions and aerosols can accelerate the growth by adding material to the small aerosols and thereby help them survive to become cloud condensation nuclei.
So we had minute trace gases as you have in the real atmosphere, of sulfur dioxide and ozone and water vapor, and then by keeping these things constant and just changing the ionization [the abundance of electrically charged atoms] in the chamber a little bit, we could see that we could produce these small aerosols, which are the basic building blocks for cloud condensation nuclei.
1950 - 1970s through is for transition from mostly coal (larger aerosols that fall out quickly) to mostly oil based economy and post war economic boom (smaller aerosols, more sulfates), as far as I know it.
I would suggest these small aerosols have a large effect on the saturated adiabatic cooling and heating cycles and the transport of water vapor latent heat poleward.
The condition that Ferdinand mentioned may be more likely related to very small aerosols.
The model that is most consistent with the observed evolution has the smallest aerosol forcing.
The smaller the aerosol, the greater the proportion of potassium — those collected early in the morning were the smallest and richest in potassium.
