This is also one of the sources of uncertainty in sea conditions.Uncertainty in sea conditions refers to the inherent variability and unpredictability of ocean environments, impacting marine activities and predictions. This uncertainty stems from various factors, including limitations in our ability to model complex ocean dynamics, limitations in our ability to measure sea conditions, and the inherent variability of natural systems.

Second-harmonic term explains sharper crests; include it when analysing overtopping or slamming loads.

This single relation lets you jump between period, wavelength and depth; solve it iteratively for k whenever d/λ is unknown.

Horizontal particle speed decays exponentially with depth.

KC<2 inertia-dominated; KC>20 drag-dominated; mid-range needs both.

Special attention should be paid here, as it is very easy to confuse

Do a dynamic wind check if structure is tall, light, or has a low natural frequency.

Wind pressure grows with the square of wind speed, so small speed changes really matter.
