Wind chimes are thought to be good luck in parts of Asia and are used in Feng Shui. Wind chimes started to become modernized around 1100 B.C. after the Chinese began to cast bells. A bell without a clapper, called a "yong-zhong", was crafted by skilled metal artisans and primarily used in religious ceremonies. Afterwards, the Chinese created the "feng-ling", which is similar to today's modern wind bell. Feng-lings were hung from
Wind wave the wave climate, therefore estimating the effect of wind waves is important for managing littoral environments. A wind generated wave can be predicted based on two parameters: wind speed at 10 m above the sea level and wind duration, which must blow over long periods of time to be considered fully developed. The significant wave height and peak frequency can then be predicted for a certain fetch length. Ocean water waves generate land seismic waves that propagate hundreds of kilometers into the land. These seismic signals usually have the period of 6 ± 2 seconds. Such recordings were first reported
