BLDU decode stands for?

• A. Blowing snow
• B. Blowing rain
• C. Blowing dust
• D. Blowing fog

Answer: (C)

Understanding METAR weather phenomenon abbreviations helps you translate what a report is telling you about horizon visibility and air conditions. BLDU is the shorthand used in METARs to indicate blowing dust. This means winds are strong enough to lift dust into the air, creating dust in the atmosphere and often reducing ground visibility. It’s a typical condition in arid or dusty areas and can significantly affect takeoff and landing operations, as pilots and dispatchers must factor in lower visibility and potentially abrupt changes as dust is stirred up. Blowing snow has its own code (indicating snow being blown by the wind), and other conditions like rain or fog use different identifiers. So the term that matches the described weather effect—dust being carried by the wind and reducing visibility—is blowing dust.
