Global wind speed increase, wind power generation significantly increase?

In a paper published by the international joint research team in the journal Nature Climate Change, it was revealed that the decline in global wind speeds since the 1970s has ended and the wind has been increasing year by year since 2010.

The paper found that in less than 10 years from 2010 to 2019, the world average wind speed increased from 7 mph, i.e. 11.2 km/h to 7.4 mph, to 11.9 km/h. As a result, wind power generation has increased by 17%. In the United States, wind power generation has been increasing every year since 2010, and the paper says that half of the increase can be explained by the increase in wind speed.

Wind speed declines have been observed on a global scale for 40 years from the 1970s to 2010. This phenomenon brought various speculations, but according to one specialized media, it was a prevailing theory at the time that the airflow was blocked as a result of irregularities on the earth’s surface due to urban development or the like.

However, the increase in customs since 2010 overturned this theory. The paper released by the research team explains that the series of wind speed changes are likely to be caused by large-scale climate cycles. As a result of analyzing factors that can affect winds around the world using the model, the research team found that the patterns of temperature changes by regions around the world had a significant influence on wind speed. If there is a temperature difference between adjacent regions, winds such as marine winds are generated. This kind of wind was affecting wind speed.

The paper pointed out that as a result of changes in certain natural climates, wind speeds have shifted from decreasing trend to upward trend. Since patterns of temperature change tend to persist for decades, wind speed imaginations that have continued since 2010 can last for more than 10 years. If the growth trend continues from 2010 to 2019, it is said that wind power generation in 2024 is likely to increase by up to 37%.

The thesis also points out that the wind power industry needs to plan in advance for wind speed increase or decrease due to natural phenomena because the amount of wind power generation changes greatly according to the natural cycle. Related information can be found here .
