Welcome to the newest edition of The Why. “Why does the wind blow?” you ask? Good question although it almost seems like we’re doing someone’s homework again. (Still, it beats answering the question: “Why does the wind cry Mary?” Seriously? Do you really think that we here at American Live Wire are not fans of the late, great Jimi Hendrix? Oh please! You must be in a “Purple Haze” there, “Foxy Lady”. “The Wins Cries Mary” was The Jimi Hendrix Experience’s third single and hit the record racks in 1967 when even yours truly was but a wee lad.)
Now let’s get to today’s question, shall we? Why does the wind blow? It has been a long time since anyone on staff has studied this but it has to do in part to temperature. Specifically, it has to do with the temperature of the Earth and the atmosphere.
As per usual though, it’s always good to get confirmation. Surprisingly, some Yahoo Posters actually proved to be helpful. “Tom B” had a great point: He said: “The way to think about it is that the wind doesn’t blow, it’s just that air moves from high pressure to lower pressure.”
“Akshatha.R.Prabhu” explains what wind is in simple terms. (It’s caused by a) “pressure difference. The molecules in air generally flow from areas of higher pressure to areas of lower pressure. This flow of air is what we call wind.”
As to why the wind blows “Prabhu” says: “As the sun warms the earth’s surface, the atmosphere warms too. Some parts of the earth receive direct rays from the sun all year and are always warm. Other places receive indirect rays, so the climate is colder. Warm air, which weighs less than cool air, rises. Then cool air moves in and replaces the rising warm air. This movement of air is also makes the wind blow.”
This is confirmed by multiples sites including The Weather Wiz Kids. (In fact, his post appears to have been copied and pasted directly from The Weather Wiz Kids website. It’s OK though we aren’t the plagiarism police, mmmkay? The important thing is we have an answer.)
