Polar Jet Stream Series

The path of the jet stream is in constant motion. Consisting of westerly air currents that are flowing and meandering masses streaming at high altitude, they flow at about 30,000-39,000 feet above sea level. Generally following an annual cycle, the wind speed and extent of coverage is much greater in the winter and diminishes in the summer.

Polar Jet Stream is a permanently installed cast bronze sculpture based on the pattern of the jet stream over the entire Northern Hemisphere as it was captured on April 18, 2015.

​

Zooming in geographically but expanding temporally, Jet Stream Over North America is a scientific animation capturing a full year of the seasonable variability of the jet stream illustrated as simplified black to white gradation maps from 2017. The white areas illustrate the greatest wind speeds.
