• 2010 to 2015

Which season showed the worst performance in severe thunderstorm warnings?

• Fall

• Summer

• Spring

• Winter

What factor significantly affects the detection of wind events?

• Time of day

• Distance from radar

• Humidity

• Temperature

Which region tends to have better performance due to higher population density?

• Upper Midwest

• Ohio Valley

• South

• Northeast

What is one of the general conclusions about severe thunderstorm warning performance?

• Experience does not affect performance

What is a suggested focus for future training?

• Improving hail detection

• Enhancing wind event detection

• Reducing false alarm rates

• Increasing radar coverage

What human factor can lead to sub-optimal decisions in warning issuance?

• Inadequate data collection

• Lack of training

• Emphasis on traditional statistics

• Over-reliance on technology

What is a limitation mentioned in the study regarding storm data?

• Limited geographical coverage

• Inaccurate population density estimates

• Inconsistent data collection methods

• Variability in verification efforts by different WFOs
