Study Notes
Tornado Safety and Misconceptions
- Taking shelter from a tornado under a highway overpass is not safe.
- Tornado reports should specify duration and proximity to landmarks, such as stating a tornado has been active for over 5 minutes near Anadarko, OK.
Atmospheric Phenomena
- Mesoscale refers to atmospheric events that can range from a few miles to hundreds of miles, including thunderstorm complexes and tropical storm precipitation bands.
- Low pressure systems are characterized by inward spiraling and ascending air circulation, while high pressure systems involve descending, outward spiraling air movements.
Flash Flooding and Weather Alerts
- Most fatalities from flash floods occur elsewhere, challenging common beliefs.
- The National Weather Service (NWS) issues advisories for weather events below warning criteria, warnings for imminent severe weather, and watches for conditions favorable to severe weather.
Tornado and Thunderstorm Data
- The U.S. experiences approximately 1,000 tornadoes annually.
- Severe thunderstorm wind speed is defined as 58 MPH by the NWS.
Thunderstorm Development and Characteristics
- The Cumulus Stage marks the first phase of a thunderstorm.
- Key ingredients for thunderstorm formation include moisture, a lifting mechanism, and instability.
Severe Weather Indicators
- The shelf cloud is a particular cloud type commonly associated with severe weather.
- Reports for Spotter Network can include observations like wall clouds when lightning is present, or tornado sightings during particular sky conditions.
Thunderstorm Dynamics
- The Mature Stage of a thunderstorm is most likely to produce large hail and damaging winds.
- Supercells are the type of thunderstorms responsible for producing nearly all significant tornadoes.
Report Integrity on Spotter Network
- Reporting privileges on Spotter Network can be revoked after two low-quality reports, requiring retraining for reinstatement.
