In fact, the addition of dust particles could instead create more water droplets too small to rain down or even build a respectable cloud.

Indeed, conventional wisdom held that higher levels of aerosol pollution in the atmosphere should cool the earth's climate because aerosols can increase cloudiness; they not only reduce precipitation, which raises the water content in clouds, but they also increase the size of the individual water droplets, which in turn causes more warming sunlight to be reflected back into space.

More droplets mean whiter clouds that bounce more solar energy away from EaMore droplets mean whiter clouds that bounce more solar energy away from Eamore solar energy away from Earth.

Although droplets are thousands of times more numerous, previous studies have shown that adding even a small number of ice crystals to these clouds can lead to a fast dissipation of the cloud water.

More and smaller droplets change things for the clouds.

«We found that exposing particles to sunlight makes the particles increasingly more oxidized and acidic, which in turn makes it easier for such particles to nucleate water and make cloud droplets,» said Professor Sergey Nizkorodov, a physical chemist at UCI who led the study.

There are an ever increasing number of these «indirect effects», but the two most discussed are the aerosol / cloud opacity interaction (more aerosols provide more sites for water to condense in clouds, thus cloud droplets are smaller and clouds become more opaque), and the cloud lifetime effect (smaller droplets make it more difficult to make drops big enough to rain, and so clouds live longer).

It is my understanding that the uncertainties regarding climate sensitivity to a nominal 2XCO2 forcing is primarily a function of the uncertainties in (1) future atmospheric aerosol concentrations; both sulfate - type (cooling) and black carbon - type (warming), (2) feedbacks associated with aerosol effects on the properties of clouds (e.g. will cloud droplets become more reflective?)

This argument hinges on the contention that more water vapor means greater density of water droplets in the active rising updraft of the storm clouds.

I'm not sure offhand of the importance of this, but more rapid cooling from more rapid ascent would reduce the distances over which molecules can diffuse during the time periods involved, which would tend to isolate the effects of the particles from each other, so that more haze particles could go on to become cloud droplets, resulting in smaller and more numerous cloud droplets.

You can prove this by looking at thick clouds about to rain — they're darker because increased droplet size means more direct backscattering, less light diffusely scattered.»

This doesn't make sense — more pollution, or more specifically, more Cloud Condensation Nuclei from sulfate or particulate emissions, result in more droplets.

More trees mean more moisture cycling, as well as more cloud and droplet nucleation from leaf emissions such as terpenes and bacteMore trees mean more moisture cycling, as well as more cloud and droplet nucleation from leaf emissions such as terpenes and bactemore moisture cycling, as well as more cloud and droplet nucleation from leaf emissions such as terpenes and bactemore cloud and droplet nucleation from leaf emissions such as terpenes and bacteria.

Latham's idea, which he first published in the science journalNaturein 1990, is to make the silver linings of those stratocumulus clouds a little bit more silvery, by injecting salt crystals into the atmosphere to seed the formation of the water droplets that comprise them.

These particles would create more water droplets, increasing the clouds» density and making them more reflective.

And of course bright white clouds can to reflect more sunlight than the yellowish droplets of pure sulfuric acid, but the water clouds also evaporate.

Increased numbers of aerosols provide additional locations for droplet nucleation and, all else being equal, result in clouds with more and smaller droplets hence being more reflective to solar radiation (a cooling effect).

If Svensmark and other researchers are correct the switch between these states could be due to weakness in the solar wind leading to more galactic cosmic rays entering the atmosphere and increasing the nucleation for cloud droplets (just as in a «cloud chamber»).

Obviously the clouds are bigger and they have «more stories», and up drafting droplets do better job than a fixed grid of metal.

Pollution has increased the number of particles, which makes the cloud droplets smaller and more numerous.

It furthermore ignores the fact that CO2 readily dissolves in water, especially at low temperatures and increased surfaces, such as in the top of clouds where the surface to volume ratio of tiny water droplets is more than 10000 times that at the surface.

As more water droplets are created, clouds would appear larger and brighter.

The aim is to increase the water droplet content of the clouds, making them reflect more sunlight — so called marine cloud brightening.

We do not assume that albedo will increase on average to reject more heat, both through cloud SW rejection, and reduction of the distance water droplet LW needs to travel to escape to space.

Clean air causing greater supersaturate larger droplets size, more ice and mixed phase cloud formation etc. etc..

The heat pipe analogy is more appropriate to the whole hydrological cycle, the essential energetics of which occur at the surface (the hot evaporating end), in the clouds where the larger water droplets accelerate condensation, and in precipitation, which converts very slowly acquired potential energy back into kinetic and thermal energy very quickly.

a) decreases («dimming») until the 1980s, because atmospheric pollutants (aerosols) make the atmosphere more reflective and also clouds, by increasing the number of water droplets in the clouds, which in turn increases the amount of sunlight reflected, and subsequent

Cloud droplets, for example, might be a couple hundredths of a millimeter in diameter, while the smallest grid cells that are considered in a model may be more like a couple hundred kilometers across.

Large droplets in rain clouds scattering light much more effectively than small droplets — it's why thunderclouds are very dark underneath and why Venus has high albedo.

Overall, the evidence suggests that the aerosol buildup is causing a net cooling both because aerosols reflect incoming sunlight back to space (a direct effect) and because they «seed» cloud droplets, causing clouds to become brighter and more reflective (an indirect effect).

The main idea is that more CCN causes liquid clouds to consist of more, but smaller, droplets.

In other words, a rain cloud would hypothetically form when conditions are right in any event, but, when there are more cosmic rays, the cloud would not rain out until later in the day because the smaller initial droplet size would affect how long the droplets take to coalesce into the size necessary for rain to happen or something to that effect.

In a warmer world, air holds more water vapor, so when cloud conditions are right for that vapor to form droplets, more precipitation falls.
