If the current and wind are in the same direction, what does the sea surface represent concern the true wind speed?

Question 1 of 27070

If the current and wind are in the same direction, what does the sea surface represent concern the true wind speed?

🔍 Key Concepts

• Difference between true wind and apparent wind • How current flowing with the wind affects wave height and steepness • How mariners often estimate wind speed from sea state

💭 Think About

• If wind and current move in the same direction, what happens to the size and steepness of the waves compared to the same wind with no current? • If you judged wind speed only by the look of the sea surface in that situation, would you tend to think the wind is stronger, weaker, or unchanged? • How do training wind–sea state tables (like Beaufort scale descriptions) assume the current is behaving?

✅ Before You Answer

• Be clear on the definition of true wind (wind over the earth’s surface) vs what you estimate from wave appearance • Think about whether following current makes waves build up or lay down/flatten out for the same true wind • Ask: Would this sea state make a mariner underestimate or overestimate the true wind speed?

Question 1 of 27070

If the current and wind are in the same direction, what does the sea surface represent concern the true wind speed?

It appears less than actually exists

The appearance of the sea surface does not change

It appears at the correct speed

It appears higher than actually exists
