Okay, I've found a good source. It says "Imagine our little pond again, only this time notice a slight breeze is starting to blow towards you at say maybe at 5-10 nautical miles per hour (kts). It's starting to texture the surface of the pond, nothing really measurable, but texture nonetheless. How is this happening? In short, molecules of moving air, being pushed by the breeze, are rubbing against the surface of the water, causing some water molecules on the surface to move in the same direction as the wind. As a few molecules of water start moving, they collide with others and set them in motion, and as the air keeps moving, so does the water. It's just basic friction.

Now imaging the wind is kicking up a bit more, like say to 20 kts. As would be expected, the water texture turns a bit choppier as more and more molecules are set in motion. Over distance, the little chops start merging to create larger chops. As chops combine, the energy present in each one creates a larger and more energetic chop. The more energy, the faster the chop moves. The little chops have height, and they travel with a measurable speed, and if you could follow an individual one, you could measure the amount of time it takes to travel from one side of the pond to the other. As the wind continues to pick up, now to nearly gale force (34 kts), the chops are starting to whitecap and it starts looking downright stormy. The chops start combining into wind waves and they are bigger and moving faster still, and have more momentum energy associated with them.

But let's consider a real open-ocean storm. Some storms are small in size but have very strong winds, while others are huge in size but have comparatively less wind velocity. Hurricanes are relatively small storms, that is, they rarely exceed more than 500 nautical miles (nmiles) in diameter, but can have maximum sustained wind speeds of over 150 mph over a small area near the center. Conversely, strong winter storms can cover well over a thousand miles but typically have sustained wind speeds of only 50-60 kts. Both are capable of making big wind waves, but not all wind waves are the same."
