| Visualization of wind data with flexible particles | |
|---|---|
Since May 17th 2006, the weather forecast company meteomedia produces the flow visualization movie, well known from the German news Tagesthemen, with the special tool ssflowvis, developed by Matthias Schäfer and Benjamin Seibold. A particular feature is efficient particle management. Without notice to the viewer particles are removed from clusters, as well as particles are inserted into holes and gaps. Also in- and outflow boundaries are treated naturally. The particle management allows particles to live long, thus it can be efficiently visualized which paths air currents take. | |

| Smooth animation of cloud data | |
Since August 10th 2006 the television weather forecast show Das Wetter im Ersten presents an animation of cloud movement for the next 36 hours. The forecast data is available in time resolution of 3 hours. The method ssclouds, developed by Matthias Schäfer and Benjamin Seibold, interpolates the between two images in such a way, that a smooth movement arises. A particular chellenge is the correct treatment of clouds which flow in at boundaries. Multiple cloud layers are considered. | |

Similar challenges as with the cloud animation, plus additional problems specific to precipitation. | |
