What does the weather code GR mean?

• A. Hail
• B. Fog
• C. Dust
• D. Mist

Answer: (A)

In aviation weather reporting, many weather phenomena are written as two-letter abbreviations. The code GR is used to denote hail, a form of solid precipitation made of ice pellets that form in strong updrafts inside thunderstorm clouds. This is why GR points to hail specifically. The other possibilities have different codes: fog is FG, mist is BR, and dust is DU or DS, so none of them use the GR code.
