What does "BL" stand for in a METAR report?

Blowing
Blizzard
Blinded
Brief

The correct answer is: Blowing

In a METAR report, "BL" stands for "Blowing." This designation is used to indicate that blowing snow or sand is present at the reporting station, which can significantly impact visibility and pilot operations. The phenomenon occurs when loose particles are lifted by wind from the ground, creating hazardous conditions. Understanding this term is crucial for pilots, as it alerts them to potential challenges they may face during takeoff, landing, or in-flight maneuvers, especially in winter conditions or sandy regions. The other choices do not correspond to the standard abbreviations in METAR reports. "Blizzard" relates to a severe weather condition but is not an abbreviation used in METAR; "Blinded" is not a term found in aviation weather reporting, and "Brief" does not accurately describe any conditions noted in METAR observations. Thus, recognizing "BL" as "Blowing" provides vital information for ensuring flight safety and effective decision-making in variable weather conditions.
