Wind turbines (high-tech windmills) can generate power in places far from power plants and without an electricity grid—but planners need to know where there is sufficient wind for the turbines to operate efficiently.

In less than a decade, the global average wind speed has increased from about 7 mph to about 7.4 mph. Explore our digital archive back to 1845, including articles by more than 150 Nobel Prize winners. That could be a boon for the wind power industry in the near future. A study published yesterday in the journal Nature Climate Change finds that winds across much of North America, Europe and Asia have been growing faster since about 2010.

But within that larger, long-term warming pattern, temperatures in these regions also tend to naturally cycle back and forth between warmer and cooler periods, sometimes lasting decades at a time. © 2020 Scientific American, a Division of Springer Nature America, Inc. Support our award-winning coverage of advances in science & technology. While some theories are more controversial than others, recent studies have drawn connections between climate change and the behavior of the Northern Hemisphere jet stream, the westerly winds around Antarctica and other air circulation patterns around the world. The study may help put to rest a scientific debate that's perplexed researchers for years. Temperature differences between neighboring regions, or between the ocean and nearby land areas, can affect the flow of air. Discover world-changing science. Private companies are using these data to design, build, and market new technologies for harnessing this energy. The recent reversal suggests that some other factor must be playing a bigger role.

Using models to investigate the factors that influence the behavior of global winds, the researchers found that big climate patterns — which affect temperatures in certain parts of the world — have a major influence on wind speeds. Before global wind speeds picked up in 2010, they had been decreasing for several decades, starting in the 1970s. Image of the Day And some modeling studies have suggested that continued warming could cause substantial shifts in the regions with the most potential wind power around the world — namely, declines in the Northern Hemisphere and some potential gains in the global South.

Wind turbines (high-tech windmills) can generate power in places far from power plants and without an electricity grid—but planners need to know where there is sufficient wind for the turbines to operate efficiently. The authors of the new study suggest that a shift between certain natural climate cycles may have helped trigger the switch from slower to faster winds.

Atmosphere And if climate fluctuations really do have such a big effect, there's also the question of how future climate change may factor in. If natural climate cycles can cause such major changes in global wind speeds, the industry should plan for potential ups and downs. For the average wind turbine, that translates to a 17% increase in potential wind energy.  Data Date, Data acquired October 9, 2001 Maps show the average (mean) wind speed as well as two components of wind direction: U-wind represents the east-west component of wind and V-wind represents the north-south component. This image shows a satellite-based estimate of offshore wind power potential in the Atlantic Ocean southeast of Brazil. For instance, the researchers found that wind speeds tend to be slower across much of the Northern Hemisphere when temperatures are warmer in parts of the tropical Atlantic and the western Pacific and over Greenland. Global maps of average wind speed help researchers determine where to develop wind energy. Private companies are using these data to design, build, and market new technologies for harnessing this energy. But if that were the case, wind speeds should still be slowing down now — not speeding up. For more information, read Power to the People, Image of the Day Data acquired October 9, 2001, A catalog of NASA images and animations of our home planet, Atmosphere > Atmospheric Winds > Surface Winds. Scientists floated a variety of theories about the "global stilling," as it came to be called. Global maps of average wind speed help researchers determine where to develop wind energy. Global maps of average wind speed help researchers determine where to develop wind energy. Wind Speeds off the Coast of Southern Brazil, NASA Goddard Space One of the most popular ideas suggested that increasing urban development and other land-use changes had altered the surface of the Earth, making it rougher and increasing the amount of drag acting on the flow of air around the world. E&E provides daily coverage of essential energy and environmental news a twww.eenews.net. That might explain about half the increase in U.S. wind power capacity since 2010, researchers say. End Date: Small terrain features, vegetation, buildings, and atmospheric effects may cause the wind speed to depart from the map estimates. With this tool, called “Earth Wind Map”, an animated map of global wind, weather, and ocean conditions, you can see current wind speeds all over the Earth, in real-time! Water. In less than a decade, the global average wind speed has increased from about 7 mph to about 7.4 mph. If the current pattern continues, the authors suggest that average global power generation could increase by as much as 37% by 2024.
