January 14, 2013. Height Sea waves rise from the eastern coast of Australia, and Indonesia and near Antarctica, but the decrease in some other areas, according to an international team of scientists.
The waves act as intermediaries continuous exchange of heat, power, water, steam and gases between the atmosphere and the ocean. They always change the height, frequency and direction of the wind and other factors, which, in turn, depend on the climate.
Researchers have attempted to predict the characteristics of the waves in the next century with the help of five different computer models according to changes in climate predicted in "
The paper concludes that height waves grow in Indonesia, the Southern Ocean and the east coast of Australia as a result of the shift of the Southern Annular Mode (Antarctic oscillation) and strengthening of westerly winds in the Southern Ocean.
Also projected to decrease wave heights of more than one quarter of the world's oceans, especially in the Northern Hemisphere. The reason may be offset Pacific anticyclone zone to the north.
A calm sea in the North Atlantic will contribute to security of shipping routes. This fact will appreciate the deep-sea fishermen, who are allowed to work if wave not more than 2-5 m, depending on vessel size.
As for the impact on coastal areas, then, for example, in the northern part of the Pacific Ocean wave power reduction will reduce coastal erosion, but at the same time suffer the corresponding area of energy.
The study is published in the journal
