🔍 Key Concepts

• Rotary currents and how predicted set and drift can be modified by local conditions • Effect of a strong, steady wind on the direction (set) and speed (drift) of surface currents in relatively shallow water • Relationship between wind direction stated as "from" (e.g., north-northeasterly) and the direction the water will be pushed toward

💭 Think About

• First, visualize the predicted current: in what compass direction is 355° pointing, and how fast is 0.8 knot compared to the answer choices? • Next, decide: a strong north-northeasterly wind blows from NNE; which general direction will this push surface water toward? How would that change the current set compared to 355°? • Consider whether a 30 mph wind is likely to increase, decrease, or have little effect on the current speed, and compare that to the drifts (speeds) given in the choices.

✅ Before You Answer

• Be clear on wind convention: north-northeasterly means the wind is coming FROM NNE, not blowing toward it. • Compare each choice’s direction to the predicted 355°: which choices show a current being turned more toward where the wind is pushing the water? • Check which drifts (speeds) are close to 0.8 knot and whether a strong, sustained wind would more likely make the current slightly stronger or much weaker.
