🔍 Key Concepts

• Decode the wind barb symbols used on surface analysis charts • Remember that each full barb and half barb represents a specific wind speed in knots • Wind speed is read from the number and type of barbs, not from isobars or pressure values

💭 Think About

• Look closely at the station model at position C and count exactly how many barbs are on the wind arrow and whether any are half-length • Recall the standard knot values assigned to a full barb, a half barb, and a pennant, then total them for position C • Compare your calculated wind speed with the multiple‑choice options and decide which one matches

✅ Before You Answer

• Be sure you are reading only the wind barb at C, not A, B, D, or E • Confirm you know the standard coding: full barb = ? knots, half barb = ? knots, pennant (triangle) = ? knots • Double‑check that you’re not confusing wind direction (where the arrow points) with wind speed (number/type of barbs)
