The USU team studied long-suspected patterns against temperature measurements, precipitation readings, tree-ring data and Great Salt Lake levels.

And when the ocean temperatures approach their warmest, a drought begins digging in. The pattern does not apply for southern Utah and its distinct climate pattern.
