Which term describes how strong the wind is?

The term that accurately describes how strong the wind is would be associated with wind strength. Wind strength refers to the intensity or force of the wind, which can be measured using instruments like an anemometer. It indicates the impact that wind has on the environment, affecting erosion, sediment transport, and other coastal processes.

Wind pressure, while related to the impact of wind, refers to the force exerted by the wind against surfaces and is not a direct measure of how strong the wind is. Wind velocity measures the speed of the wind along a particular direction, which is important but does not specifically convey the strength aspect alone. Wind force may be used to describe the effect of wind in relation to its strength and speed, but it is less commonly used than wind strength to denote the concept of strength alone.

Therefore, wind strength is the most direct term used to describe the intensity of the wind itself.
