POLAR PLOT DESCRIPTION

The standard CDIP spectral file is converted into a 2-dimensional frequency/direction spectrum and displayed on a polar coordinate system. The Maximum Entropty Method is used to create the 2D spectrum; this gives a narrow directional spectrum that CDIP considers appropriate for swell in the Pacific.

The polar plot is useful for identifying individual wave events based on their directions and wave periods.
