scientists who turn hurricanes into music

A hurricane lifetime can last anywhere from a day to a few weeks. Agencies such as the U.S. National Oceanic and Atmospheric Administration continuously measure all sorts of features of a storm. We distilled the changing characteristics of a hurricane into four features measured every six hours: air pressure, latitude, longitude and asymmetry, a measure of the pattern of the winds blowing around the storm’s center.


To create the sonifications, we export these data into the music synthesis program SuperCollider. Here, numerical values can be scaled and transposed as necessary so that, for example, a storm lasting several days can be played over just a few minutes or seconds. Each type of data is then treated like a part in a musical score. Data are used to “play” synthesized instruments that have been created to make sounds suggestive of a storm and to blend well together.
