Weather-ology: The Myth of the Anemoi

Long before modern science began to understand the processes that create our weather, people made up their own explanations. Many of these accounts were fantastic in nature, with evil or benevolent gods, monsters, and spirits controlling the elements. In this series, we’ll explore some of these ancient myths and share the science behind them. Weather + mythology = weather-ology!

To our early ancestors, the wind must have been a real mystery. One moment, the air would be still and stifling, and in the next, a refreshing breeze could move through. Later, a gale might blow in, destroying massive trees or even buildings. The wind came in from different directions and had different temperaments. Sometimes it was helpful, and other times it seemed almost vengeful in its fury. What was going on?

To the ancient Greeks, this split personality was easily explained. They believed there were four wind gods — one representing each cardinal direction — each with a personality of his own. Like the other gods of Olympus, the wind gods, known collectively as the Anemoi, came complete with very human flaws, and could be benevolent or cruel, as the mood struck them.

These gods were Boreas, god of the north wind, Notus, god of the south wind, Zephyrus god of the west wind, and Eurus, god of the east wind. In addition to each representing his own direction, each of the Anemoi was associated with a specific type of wind. Boreas brought biting cold winter winds. Notus was in charge of the raging storms of late summer and autumn. And Zephyrus brought light breezes during the spring and early summer. Eurus was associated with bad luck. His wind was often accompanied by warm rain.

The Anemoi were most often depicted as winged men. As men, they often got up to mischief, including abducting women for their own pleasure (a common pastime among the gods). They could also become invisible, taking the form of gusts of wind, or become horses.

When a storm or other wind related occurrence worked to the benefit of a person or people — as when the Persian army was prevented from attacking Athens due to a powerful storm at sea — it was said to be sign of the gods’ favor.

Today, we know that the wind is simply a part of nature, with no will of its own. Though it can be beneficial or devastating, it blows without regard for its effect on humans.

Wind occurs when there is a difference in air pressure between one area of the Earth’s surface and another. Air naturally moves from areas of higher pressure into areas of lower pressure. Sometimes the difference in pressure is minor, resulting in a gentle breeze. At other times, the difference is greater, resulting in violent winds that move faster than 250 miles per hour (the fastest wind ever recorded was clocked at 253 miles per hour on April 10, 1996, on Barrow Island, Australia).

Because of the Earth’s rotation, however, the air does not move in a straight line from the point of highest pressure to the point of lowest pressure. The Earth’s rotation pushes the air to the right. This phenomenon, called the Coriolis Effect, causes air to flow clockwise around high pressure areas in the Northern Hemisphere and counter-clockwise around low pressure areas. The reverse happens in the Southern Hemisphere.

Before we knew about air pressure, though, the ancient Greeks had no explanation for wind other than the whims of a capricious group of supernatural beings. And so, the four winds were born.

[…] The Anemoi are one of the coolest sets of Gods in Greek mythology. The Greeks believed that all of the winds had a distinct personality, and assigned each of them a separate God. The Gods are Zephyros of the west wind, Euros of the east, Boreas of the north, and Notos of the south wind. Sometimes in the stories, the Anemoi look like men with enormous wingspans; other times, they are shown in the form of incredible horses of breathtaking majesty. Sometimes the Anemoi were represented as being controlled by Aiolos, who was known as the “Horse Reiner” and had the ability to control the wind Gods to unleash horrible storms whenever the Gods wanted him to. The God Euros, associated with the East wind, was often believed to be a sign of bad luck. […]

Notus would have to be my favorite. I am totally rejuvenated during a raging thunderstorm. Not liking any damage, but the louder, and more windy the better. Nothing lifts me like a real summer storm.

I liked the article,and loved the mythological links! Perhaps a wee bit more science would help…ie,the earth’s rotational direction,and equatorial speed,which may benefit understanding…(or not!).

According to the Bible (Revelation) The cardinal winds, N,S,E,W, are mostly benigh. Those that blow from the 4 corners or the then known earth, ie. N-E, N,W, S-E, S-W are distructive and evil.

If you notice a hole in the upper left-hand corner of your Farmers' Almanac, don't return it to the store! That hole isn't a defect; it's a part of history. Starting with the first edition of the Farmers' Almanac in 1818, readers used to nail holes into the corners to hang it up in their homes, barns, and outhouses (to provide both reading material and toilet paper). In 1919, the Almanac's publishers began pre-drilling holes in the corners to make it even easier for readers to keep all of that invaluable information (and paper) handy.
