Quiz: 6 Questions To See How Much You Know About Aviation Weather

Live from the Flight Deck

Weather is always a mixed bag. Are you ready to handle it?


  1. 1) What type of cloud is this, and what weather is associated with it?

  2. 2) Which answer describes a low pressure system near the surface (northern hemisphere)?

    A low pressure system at the surface flows counter-clockwise and converges at the center of the low pressure system.

    A low pressure system at the surface flows counter-clockwise and converges at the center of the low pressure system.

  3. 3) What three things are needed to form a thunderstorm?

    High humidity, unstable atmosphere, and a lifting force are the ingredients needed to make a thunderstorm.

  4. 4) What type of fog is associated with moist air moving over a cool surface?

    Advection fog is associated with moist air moving over a cooler surface.

  5. 5) You're at Seattle-Tacoma International airport (433' MSL) and it's a standard day (ISA). Approximately what altitude would you find a temperature of -1 degrees Celsius?

    The standard lapse rate is 2 degrees for every thousand feet. ISA standard temperature at 433'MSL is approximately 14 degrees. The difference between 14 and -1 is 15 degrees. Dividing this value by 2 (two degrees per thousand feet) will give 7.5. Multiply this value by 1,000 and you get an altitude of 7,500 ft.

    Mixed ice is a cloudy combination of clear and rime ice. It's often found in stratiform clouds, with the most intense icing near the top of the cloud.
