Wave intelligence
The systems in the sea
A buoy's significant wave height sums everything in the sea: long groundswell from a storm a thousand miles off, a closer swell, the chop of the local wind. Each buoy's measured directional spectrum is partitioned into those systems, which are followed through time, used to place the storms the swells came from, and checked for seas that cross.

The wave systems in each buoy's latest spectrum, largest first, and whether each is building or fading.
Each petal is a system, pointing to where it comes from, north up. Its length grows with height (the ring is 4 m); its width is the directional spread. Swell Wind sea Storm placed
