List of ice storms

Definition
A List of ice storms is a compiled reference that enumerates notable ice storm events, typically organized chronologically or geographically, and provides brief information on each storm’s date, location, severity, and impacts.

Overview
Lists of ice storms are commonly found in encyclopedic resources, meteorological databases, and online platforms such as Wikipedia. They serve as a convenient summary for researchers, policymakers, educators, and the general public to examine the occurrence and consequences of ice storms over time. Entries often include the year and region of the event, a concise description of the storm’s meteorological characteristics (e.g., accumulation of freezing rain, ice thickness), reported damages, fatalities, and any associated emergency responses. Some lists also link to more detailed articles or reports on individual storms.

Etymology / Origin

• Ice storm: The compound noun combines “ice,” from Old English īs meaning “frozen water,” and “storm,” from Old English storm meaning “violent weather.” The term has been used in meteorological literature since at least the early 20th century to describe a severe weather event in which freezing rain coats surfaces with a substantial layer of ice.
• List: Derived from Old French liste and Latin lista meaning “strip of paper” or “roll of parchment,” the word entered English in the 14th century to denote a series of items written or recorded sequentially.

Characteristics
While the list itself is a catalog, the entries it contains share common features typical of ice storms:

1. Freezing Rain – Precipitation that falls as liquid rain but freezes upon contact with surfaces at temperatures below 0 °C (32 °F).
2. Ice Accumulation – Build‑up of glaze ice, often measured in fractions of an inch (e.g., 0.25–2 inches), capable of causing power outages, hazardous travel conditions, and structural damage.
3. Meteorological Setup – Usually involves a shallow layer of sub‑freezing air near the surface overlain by a warmer layer aloft, allowing raindrops to refreeze.
4. Impacts – Widespread utility disruptions, tree and limb breakage, transportation accidents, agricultural losses, and, in severe cases, fatalities.
5. Geographic Distribution – Predominantly reported in temperate and sub‑arctic regions, especially the northern United States, Canada, and parts of Europe and East Asia, where the required temperature profile frequently occurs.
