FAA Ground School Practice Test

Which of the following statements is true about tornadoes in a Convective SIGMET?

1. Tornadoes are specifically forecasted

2. They indicate the presence of tornadoes

3. They are not mentioned in a Convective SIGMET

4. Tornado warnings are separate from Convective SIGMETs

The correct answer is: They indicate the presence of tornadoes

The correct answer highlights that a Convective SIGMET indicates the presence of tornadoes rather than forecasting them directly. Convective SIGMETs are issued when specific convective weather phenomena, such as thunderstorms, severe turbulence, and hail, are occurring or expected to occur. When a Convective SIGMET is issued, it may include details about conditions conducive to tornado formation, and the presence of tornadoes can be inferred from the severe weather described in the SIGMET. Although tornadoes are not explicitly forecasted within the Convective SIGMET, their occurrence is often a possibility under the conditions that such SIGMETs are addressing. This is important for pilots and aviation personnel to understand, as they need to take appropriate precautions when flying in areas where severe convection is reported. Recognizing the implications of a Convective SIGMET is vital for safety, highlighting the need to remain alert to significant weather changes that could lead to tornadoes.
