FAA Commercial Pilot Airplane (CAX)WeatherMedium
A pilot is preparing for a cross-country flight and observes a stationary front on the weather chart. What weather phenomena are typically associated with a stationary front?
- ASudden temperature drops, strong winds, and convective activity.
- BRapidly moving squall lines and severe thunderstorms.
- CProlonged periods of precipitation with gradual changes in wind and temperature.
- DClear skies, light winds, and good visibility.
Show answer & explanationAnswer & explanation
Correct answer: C. Prolonged periods of precipitation with gradual changes in wind and temperature.
A stationary front occurs when two air masses meet but neither is strong enough to displace the other. This often results in a prolonged period of relatively unchanging weather, including extended precipitation, low ceilings, and poor visibility, with gradual shifts in wind and temperature over a larger area.
Why the other options are wrong
- A. This describes the passage of a strong cold front.
- B. This is characteristic of a fast-moving cold front or pre-frontal squall line.
- D. These conditions are generally associated with high-pressure systems.
Stationary Front
A weather front that is not moving, typically characterized by a prolonged period of similar weather conditions.
- Boundary between two air masses that are not advancing.
- Often results in extended periods of precipitation and low ceilings.
- Can persist for several days, causing significant disruption to aviation.
Memory trick: Stationary stands still, bringing long rains and chill.
