A group of droughts with similar depth that form a structural neighborhood inside the table.

Glossary term
Clusters are depth neighborhoods inside the table that signal compression or fragmentation phases.
Why It Matters
Clusters reveal local concentration and can signal compression or fragmentation phases.
How Stepzero Uses It
Depth neighborhoods are monitored to detect converging pressure bands.
Example
