As the water molecules begin to move, they start to travel in circles. This circular motion of water molecules at the surface continues vertically underwater. Although, this motion decreases quickly as you go deeper in the water. Capillary waves create more water surface making it easier for the wind to grab an enven greater amount of water. This adds more energy which increases the size of the waves, making them larger and larger.
Capillary waves are almost always present in the ocean.
The capillary wave becomes a wind wave when its wavelength exceeds 0.68 inch. When the winds slow down or stop, the waves continue on their journey.
