What type of weather should you anticipate if the TAF contains the code RASN?

  • A

    Good conditions (Relative Atmosphere Stability Normal).

  • B

    Rain and Stratonimbus.

  • C

    Rain and snow mixed (sleet).

  • D

    Drizzle and mist.

Refer to figure.

  • RA = Rain
  • SN = Snow
  • RASN = A combination of the two → rain and snow mixed, commonly referred to as sleet.

"Drizzle and mist": These are abbreviated as DZ (drizzle) and BR (mist). RASN indicates heavier, more complex precipitation.

"Rain and Stratonimbus": "Stratonimbus" is not a standard meteorological term. Likely meant Nimbostratus, which is a rain-bearing cloud, but TAFs do not use cloud type names like this in weather codes.

"Relative Atmosphere Stability Normal": This is not a real meteorological acronym, just a made-up phrase that coincidentally matches "RASN".
