Meteorology · Waves — Wave Height and Wind
For a given wind speed, the maximum wave height that can develop depends on:
- AThe fetch (distance over which the wind blows) and the duration of the wind✓ Correct
- BOnly the air temperature
- CThe phase of the moon
- DThe barometric tendency alone
Explanation
Wave growth depends on wind speed, the fetch, and how long the wind blows. A sea is 'fully developed' when it cannot grow further for that wind, having reached the fetch- or duration-limited maximum. Long fetches and persistent gales build the largest seas.
