Limits RegistryPUBLIC RECORD
Limits RegistryA mobile Doppler-on-Wheels radar unit estimated a wind speed of roughly 484 km/h (301 mph), some tens of meters above the ground, inside the Bridge Creek–Moore tornado near Oklahoma City on May 3, 1999 — the highest wind speed ever attributed to a tornado. Because the reading is a radar-based estimate rather than a direct anemometer measurement, and was taken above ground level, meteorologists treat it as the highest tornadic wind speed estimate rather than a directly recorded surface value.
The question, scope, and sources behind this Registry record.
A mobile Doppler-on-Wheels radar unit estimated a wind speed of roughly 484 km/h (301 mph), some tens of meters above the ground, inside the Bridge Creek–Moore tornado near Oklahoma City on May 3, 1999 — the highest wind speed ever attributed to a tornado. Because the reading is a radar-based estimate rather than a direct anemometer measurement, and was taken above ground level, meteorologists treat it as the highest tornadic wind speed estimate rather than a directly recorded surface value.
The highest wind speed ever estimated inside a tornado using mobile Doppler radar, distinct from the highest wind speed directly measured by a fixed surface anemometer (a separate record held by a non-tornadic cyclone gust).
Change a parameter to stress-test whether a proposed result is still inside the published specification. This is an audit aid, not a proof checker.
This record has no editable parameters. Read the formal question and assumptions before challenging it.
Current frontiers derived from accepted Claims.
An observed or demonstrated result; no opposing bound is implied.
The frontier is not sacred
Most progress starts with a disagreement that survives contact with evidence. If you can push the known lower bound up or pull the upper bound down, show us the work.
≥ when you have shown that at least this value is achievable.≤ when you have shown that anything above this value is impossible.No vibes. State the value, define the scope, and link the paper, proof, code, or reproduction that lets another person check it. Editors review every challenge before the public record changes.
