Fascinated by what was happening with my pen and ink wind drawings (generated with Process.2005.01), I wanted to gain a better understanding of how winds change throughout a day. I took some electronics and programming classes and built a simple apparatus to capture wind data with weather instruments and custom software written in Processing.
For these drawings, a circle is plotted every second based on wind speed and direction. The faster the wind blows, the larger the circle and the greater the distance from the center. Circle colors are keyed to time, but every other hour draws white circles. Colors change throughout the day as the drawing adds and subtracts from itself.
