FAA Sport Pilot Airplane (SPA)WeatherMedium
A pilot is briefed that an approaching front will move quickly, produce a narrow band of towering cumulus and cumulonimbus clouds, and bring brief but intense showers followed by a rapid wind shift and clearing skies. Which type of front does this describe?
- AStationary front
- BOccluded front
- CWarm front
- DCold front
Show answer & explanationAnswer & explanation
Correct answer: D. Cold front
Cold fronts move faster than warm fronts and have a steep frontal slope, forcing warm air abruptly upward. This creates a narrow band of cumuliform clouds, brief intense precipitation, and a sharp wind shift, followed by rapid clearing.
Why the other options are wrong
- A. Stationary fronts show little movement and prolonged unsettled weather rather than brief intense activity.
- B. Occluded fronts form when a cold front overtakes a warm front, producing mixed characteristics, not this pattern.
- C. Warm fronts are slow-moving with widespread stratiform clouds and prolonged light precipitation.
Cold Front Characteristics
A cold front is the leading edge of a cold air mass advancing under and lifting a warmer air mass, producing steep frontal slopes and often violent weather.
- Faster movement than warm fronts
- Steep slope produces cumulonimbus and thunderstorms
- Weather is brief but often severe, followed by rapid clearing
Memory trick: 'Cold fronts crash in fast and hard'
