Much like on Earth, these particles act as cloud seeds around which water vapor can adhere to form cloud particles.
The key finding: cloud particles at the top of the great storm are composed of a mix of three substances: water ice, ammonia ice, and an uncertain third constituent that is possibly ammonium hydrosulfide.
According to the Wisconsin researchers, the observations are consistent with clouds of different chemical compositions existing side - by - side, although a more likely scenario is that the individual cloud particles are composed of two or all three of the materials.
«Probability density function,» a statistical representation of the likelihood of something occurring at any point in time, was used to examine cloud properties, including vertical motion, liquid and ice water content, and the conditions of cloud particle growth, including how ice crystals grow at the expense of liquid droplets.
Form bonds to create forces between particles, and collide them together inside a simulated vacuum to and create beautiful cloud particle collisions and advance through the stages.

The data obtained included the first comprehensive measurements of aerosols and cloud particles throughout the atmospheric column during the evolution of multiple deep convective storm systems.
Using liquid and ice microphysics models reduces the biases in cloud optical thicknesses to ≲ 10 %, except in cases of mistaken phase identification; most of the remaining bias is caused by differences between actual cloud particle sizes and the values assumed in the analysis.
Dlugach, Z.M., and M.I. Mishchenko, 2005: The effect of aerosol shape in retrieving optical properties of cloud particles in the planetary atmospheres from the photopolarimetric data Jupiter.
The 12 - and 11 - µm ΔBT helps to distinguish between high, thick clouds and high, thin clouds by delineating cloud phase (ice or liquid water) and cloud particle size (small or large).
Any clouds that form scatter laser light; this scattering is then detected and recorded by computers, which display the results — the size, number, and composition of cloud particles — for scientists outside the chamber.
The surfaces of the cloud particles host chemical reactions that release chlorine that came from CFCs.
Blue sky arises because of the way light scatters off dust and cloud particles, which tend to reflect back toward Earth only the smaller wavelengths — the blues and purples.
«We think this huge thunderstorm is driving these cloud particles upward, sort of like a volcano bringing up material from the depths and making it visible from outside the atmosphere,» explains Sromovsky, a senior scientist at UW - Madison and an expert on planetary atmospheres.
In the polar night, the presence of PSCs allows for a specific class of heterogeneous Cl reactions to occur on the surface of the cloud particles which turn out to be very efficient at destroying ozone.
The model included physical properties of the cloud particles as well as the ability to see convection, if it gets stronger or weaker.

The most important are: water vapor, cloud particles, and CO2, with smaller contributions coming from methane, N2O, CFCs, ozone, and aerosols.
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.
