Which of the following indicates a wind speed higher than 99 knots?

The notation for wind speed in TAFs (Terminal Aerodrome Forecasts) commonly uses a specific format where the first three digits indicate the wind direction in degrees, and the next two digits represent the wind speed in knots. When the wind speed exceeds 99 knots, the wind speed is represented in a four-digit format.

In this case, the sequence "140102KT" includes "102," which clearly indicates a wind speed of 102 knots coming from 140 degrees. Therefore, this entry fulfills the criteria of indicating a wind speed higher than 99 knots.

The other examples provided do not meet this criteria. For instance, "100102KT" indicates a direction of 100 degrees with a wind speed of 102 knots; while it does reflect a high speed, it's the four-digit clip that clearly denotes extreme wind conditions. Similarly, both "05050KT" and "18010KT" depict wind speeds of 50 knots and 10 knots respectively—well below the specified threshold of 99 knots. Hence, "140102KT" is the only option reflecting a wind speed beyond 99 knots explicitly.
