What is wind?


What is wind?

This seemingly simple question has a somewhat more complex answer.

Winds have encircled our planet since its origins. They have carried the sands of the Saharan desert as far as the Caribbean, generated vast weather systems that have battered ships and shores, and inspired great myths.

For thousands of years, humans have harnessed this invisible force. Egyptians utilized winds energy to power ships on the great Nile River. Its energy was later used to power mills for grinding grain and pumping water.  

In the epic myth The Odyssey, the Sirocco winds of the Mediterranean Sea carried Odysseus on his epic quest to return home from the ten-year Trojan War.

In 1492, the explorer Christopher Columbus discovered the Trade Winds of the North Atlantic as they blew him westward to the Caribbean islands. This would become the predominant shipping route between Europe and the Americas as late as the 20th century.

Wind has aided the development of industry and culture for thousands of years. It has served an integral role in the exploration of our planet. Today we look to wind as a source of renewable energy to responsibly power and protect our future.

Wind is the migration of gasses through the Earths atmospheres and across its surface is the result of solar radiation. As the suns rays warm the surface of the Earth, the resulting heat rises in vast thermals of low-density air. The thermals rise farther and farther away from the warm surface of the planet, at which point they begin to cool and fall to Earth again as high-density air. The cool air is pulled to the void left by rising warm air and the cycle repeats. The resulting air motion of this cyclical process is called ”wind.”
