Supplementary Material for "Broadcasting Auditory Weather Reports – A Pilot Project"

This paper reports on a pilot project between our research department and and a local radio station, investigating the use of sonification to render and present auditory weather forecasts. The sonifications include auditory markers for certain relevant time points, expected weather events like thunder, snow or fog and several auditory streams to summarize the temporal weather changes during the day. To our knowledge, this is the first utilization of sonification in a regular radio program. We introduce the sonification concept and present our design of the sonification which is oriented at combined perceptional salience and emotional truthfulness. Sound examples are given for typical weather situations in Germany and several prototypical weather conditions which tune to be connected with emotional value. We will report first experiences with this pilot project and feedback of the audience on ICAD since broadcast started in February 2003. # Examples of typical (german) weather situations Here are the sonifiations of some typical german weather situations. They are selected introduce the listener by presenting sounds for weather conditions spread all over the multi dimensional weather vector room. For each day there is a graphical plot of the important parameters that might be helpful for lerning. Additionally we provide examples of one of our very early sonification prototypes for comparison. Note that not all parameters are represented in these sounds. + **chilly but nice springtime** A bit of fog and clound in the morning, but perfectly dry and shiny the hole second half of the day.
