🔍 Key Concepts

• Wind-driven current and how strong winds over time can modify a predicted rotary current • Relationship between true wind direction and the resulting surface current set (typically 10–45° to the right of the wind in the Northern Hemisphere) • Effect of wind speed and duration on increasing or decreasing the drift (speed) of the current

💭 Think About

• First, picture the predicted current vector (323° at 0.6 knot). Then think about how a strong, steady WNW wind would tend to push the surface water relative to that. • In the Northern Hemisphere, does the surface current set exactly with the wind, directly opposite the wind, or at some angle to it? How does that affect the expected set compared to 323°? • With 40 mph of sustained wind, would you expect the current speed to be weaker than predicted, about the same, or somewhat stronger than the 0.6 knot rotary prediction?

✅ Before You Answer

• Confirm the true direction of the wind (WNW) as a bearing and visualize it on the compass rose. • Compare each answer choice’s set (direction) to both the original 323° prediction and to the likely wind-driven set relative to WNW. • Compare each answer choice’s drift (speed) with the predicted 0.6 knot and decide whether strong, sustained wind would realistically increase, decrease, or leave that speed unchanged.
