WeatherQuestion 74 of 100
During a morning survey you notice building cumulus clouds, gusty winds, and unusually crisp visibility. What does this suggest?
a.Unstable air, so expect turbulence and possible afternoon showers
b.Stable air, so expect drizzle, smooth flight, and hazy conditions
c.A surface temperature inversion that will keep the air calm all day
d.A stationary front that will hold conditions unchanged for many hours
Explanation
Cumuliform cloud growth, gusty surface winds, and sharp visibility are the classic signature of unstable air, where rising currents mix out the haze but also create turbulence and can build into showers or thunderstorms later in the day. A remote pilot should plan for rough handling and a shrinking weather window. Drizzle, smooth air, and haze belong to stable conditions, and an inversion actually caps vertical motion and traps haze near the ground.
