Computer modeling and satellite observations suggest that these tiny particles can increase storm - cloud cover over certain regions of the North Pacific by 20 to 50 percent, enough to alter storm tracks in some cases.

For the study, Dr. Toohey and his colleagues from GEOMAR and the Max Planck Institute for Meteorology in Hamburg have used an aerosol - climate model to track 70 different eruption scenarios while analyzing the distribution of the sulfur particles.

Instead of having to track all the movements of every particle in the disk using complicated computer models (so - called N - body simulations), the disk can be treated as a kind of smooth sheet that evolves over time and oscillates like a drumskin.

The team of scientists involved in this study «dropped» virtual oil particles into the NEMO ocean model and tracked where they ended up over a three month period.

By tracking the positions and properties of hundreds of millions of randomly distributed particles as they collide and annihilate each other near a black hole, the new model reveals processes that produce gamma rays with much higher energies, as well as a better likelihood of escape and detection, than ever thought possible.

These particles pose health risks to populations, especially to the medically vulnerable, By infusing CATS data directly into aerosol models, data from CATS can make a difference in tracking and responding to impacts of similar events in the future.

«This is the first full 3 - D model of a debris disk where we can watch the development of asymmetric features formed by planets, like warps and eccentric rings, and also track collisions among the particles at the same time.»

Individuals within large groups are difficult to track, so crowds are often modelled as a fluid made of particles, one for each pedestrian.

To track soot, the team developed a new way to tag particles emitted from individual sources within the climate model.
