But long-term climate predictions are still limited by the range of processes that affect Earth's atmosphere, from the chemistry of the microscopic particles that form cloud droplets to the decades-long stirrings of the seas.
42.
In warm clouds, larger cloud droplets fall at a higher terminal velocity; because at a given velocity, the drag force per unit of droplet weight on smaller droplets is larger than on large droplets.
43.
A 2011 study suggested that airplanes may produce ice particles by freezing cloud droplets that cool as they flow around the tips of propellers, over wings or over jet aircraft, and thereby unintentionally seed clouds.
44.
The amount of solar radiation reaching the ground, as well as the formation of cloud droplets occur on the molecular scale, and so they must be parameterized before they can be included in the model.
45.
For example, cloud droplet, usually with large sizes and thus very smaller �ngstr�m exponent ( nearly zero ), is spectrally neutral, which means, e . g ., the optical depth does not change with wavelength.
46.
And since the atmosphere has no shortage of cloud condensation nuclei, almost any area at the dew point will also have cloud droplets, and thus a cloud .-Brains 16 : 14, 9 May 2009 ( UTC)

Winter lightning usually occurs during the falling of snow pellets _ a mixture of ice crystals made up of supercooled cloud droplets and bigger ice particles, and typically smaller and spongier than hail, according to the authors.
48.
The detection of biomass burning aerosols were shown to decrease the cloud droplet radius within these warm layer clouds in agreement with the Albrecht effect, while simultaneously decreasing liquid water path in contrast to the Albrecht effect.
49.
As the plane circled, supercooled cloud droplets, freezing rain or freezing drizzle formed a ridge of ice on the upper surface of its wings, eventually causing the aircraft's autopilot to suddenly disconnect and the pilots to lose control.
50.
Depending on their color and chemistry, these substances variously reflect sunlight and cool the air, absorb sunlight and heat the air, or form seeds for cloud droplets that separately can either cool or heat the planet, depending on the kind of cloud.
