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.

Buoys where the two largest systems now meet at 40° or more with comparable energy, in seas of 1.5 m or more: steeper, less regular waves than the height alone suggests.
Each petal is a system, pointing to where it comes from, north up. Its length grows with height (the ring is 13 ft); its width is the directional spread. Swell Wind sea Storm placed
