Super waves appear more and more

According to a scientific study conducted by Swinburne University of Technology (Australia), the global elevation of super waves is significant in the last 25 years, averaging 0.5% per year. In some places, the increase of the super wave is measured above 1% per year.

According to Australian researchers, ocean wind speed and wave height have increased dramatically over the past 25 years . The wave height has increased by an average of 0.25% per year in the equatorial region and up to 0.5% in some areas of the coastal regions of Indonesia, China and Vietnam.

Previous climate change studies often consider, measure or predict temperature for a long time. However, the above study deeply analyzes the global changes of ocean wind speed and wave height, two of the important environmental indicators.

Leading this research team is Principal Swinburne University - Professor Ian Young, and Swinburne oceanographers Professor Alex Babanin and Dr. Stefan Zieger.

Professor Wind said: "Wind and waves control the flow of energy from the atmosphere to the ocean, so understanding the parameters and their changes on a global scale is very important. "

During the study, the scientists analyzed data from satellites over a period of 23 years from 1985 to 2008. The data show that the wind speed on most oceans increases 0.25% -0.5. % each year. For super-fast winds, the average annual growth rate is 0.75%.

'We see that there is a global trend in the last 25 years that the wind speed is increasing rapidly while the wave height is increasing but with a lower intensity. The increase rate of these indicators is very interesting . '

The increase in the height of the global super waves is significant, about 1% of the largest super waves increase an average of 0.5% annually. In some places, the increase of the super wave is measured above 1% per year.

According to Professor Young, these calculations are based on data sent from satellites.

Previous studies on ocean wind speed trends and global wave heights are mostly based on visual observations, measured at fulcrum or numerical models. Due to these limitations, researchers can only consider changing wind speed and wave height on a regional basis.

However, this study is based on data transmitted from high altitude satellites on a global scale. Since then, they have a clearer picture of the changes happening in the world's oceans.

Recently, unusually high sea levels, strong winds and large waves have threatened many routes in the town center of Bac Lieu province. These phenomena are thought to be related to the results of the above-mentioned scientific research.
