How is "00000KT" interpreted in weather reports?

• A. Calm wind
• B. Wind from the north at 0 knots
• C. No wind reported
• D. Variable winds at 0 knots

Answer: (A)

In METAR reports, "00000KT" indicates calm wind conditions. The "00000" denotes the wind direction and speed: the first part "000" refers to the direction measured in degrees true, which is 0 degrees or North, but since the speed is "00" knots, it means there is no effective wind. The "KT" signifies that the wind speed is measured in knots. Therefore, the combination of both indicates that the wind is essentially calm, as there is no measurable wind speed present. Other interpretations, like winds from the north at 0 knots or no wind reported, do not accurately reflect the standard phrasing in METAR reports. The term "variable winds" would suggest changing wind directions, which contradicts the calm nature implied by "00000KT."
