List of severe weather phenomena

Severe weather phenomena are weather conditions that are hazardous to human life and property.

Severe weather can occur under a variety of situations, but three characteristics are generally needed: a temperature or moisture boundary, moisture, and (in the event of severe, precipitation-based events) instability in the atmosphere.
