WebIn theory, low-pressure systems are responsible for creating good and strong waves. In deep low-pressure systems, wind speed is greater and more waves are generated by the power of the gusts. The friction created by these winds helps to form energy waves that travel thousands of miles until hitting final obstacles, usually coastal areas.
