Wet vs. Dry U.S. Regions

Explore average annual precipitation by state (50-state dataset), then use the mini-site pages to compare patterns, clusters, and regional climate differences.

What this site shows

This mini-site compares wetter and drier parts of the United States using a ranked, 50-state precipitation dataset (inches + millimetres). The goal is to make it easy to spot regional patterns—especially how states cluster by climate.

🌧️ Wettest states cluster in the Gulf + Southeast 🏜️ Driest states cluster in the Southwest + interior West 🧭 Region labels help compare climate patterns 📊 Rank (1→50) makes patterns visible fast
Open the Interactive Data Grid Read the Cluster Analysis Sources + Glossary

How to use: Start with the Data Grid page to interact with the full dataset. Then jump to Analysis to see wet/dry clusters summarized with mini tables and conclusions.

This site focuses on the precipitation dataset and interactive comparisons.
