Using the surface analysis in illustration D049NG below, what wind speed is reported in position C?
AI Explanation
The correct answer is D) 30 knots.
The surface analysis in illustration D049NG shows wind barbs, which indicate wind speed and direction. The wind barb at position C depicts a full wind barb and a half wind barb, which corresponds to a wind speed of 30 knots according to the standard wind barb symbology used in weather analysis.
The other answer choices are incorrect because 3 knots (A) is too low, 10 knots (B) is too low, and 20 knots (C) is too low to match the wind barb depiction at position C in the surface analysis.
