Video - Dust Devils Are Not Women's Demons

Updated on March 28, 2011

A Devil is an Evil Spirit

Whatever man can not understands he consults witchcraft. A devil is an evil spirit that is a tempter to mankind. A devil is therefore a creation of human lack of understandings and fears. Man has always considered himself superior to woman. Man’s way is the only way and whoever does differently must be connected with demons and devils. Devils are not good and according to man a devil ought to be tortured until it is completely eliminated. A woman who leaves her man no doubt must be a devil.

A Dust Devil Will Expand and Swirl Like a Charged Spider

Mankind did not understand dust devils. Dust devils have very little destruction power. Dust devils tend to form in groups with the larger dust devil being followed behind by smaller dust devils that are short-lived. A dust devil will expand and swirl like a charged spider and finally it does not destroy anything with all that effort. Considering that man considers woman to be weaker and only shouting without any tangible results to show, then man must have assumed that dust devils are as good as women who does differently from man’s way, hence the name “women’s devils” or “women demon”.

Dust Devils Are Not Women’s Demons

But dust devils are not women’s demons. That’s just man’s portrayal of retrogressive ideas and lack of understanding. A dust devil is a whirl wind which is strong, well-formed, and relatively long-lived whirlwind, ranging from about half a meter wide for the small ones to well over 10 meters wide for the larger ones. The smaller dust devils can go as 1 metre tall to well over 1000 meters tall for the large ones. The vertical motion of a dust devil is upward. Dust devils are usually harmless. In some cases, a dust devil can develop large enough to destroy property.

Dust Devils Are Not Tornadoes

Dust devils are not tornadoes. Dust devils will form in areas with strong surface heating. This is usually at the interface between different surface types, such as asphalt and dirt, irrigated fields and dirt roads, or dry vegetation and dirt roads. In addition to these you will need air temperatures above 25 degree Celsius, relative humidity of under 30 percent and wind speeds of under 10 knots.

Warm-Core Vortex

When air is heated by sun, it expands and become less dense. Less dense air will tend to rise up and will be replaced by cooler air from above. But just before the hot air start rising, there usually is a resistance between the cooler air above and the quieter warmer air below. Sooner a stability limit between the two layers is approached and all you need is just a small irregularity to cause the limit to be exceeded. Once this limit is exceeded a single bubble of warm air will shoot out and will immediately be followed by several others. A low-pressure, warm-core vortex will swirl with warm air moving up from outside and cooler air moving down from inside. And a dust devil is formed. Watch the video below which illustrates the violent nature of Dust Devils

Speeds as High as 100 Km/h

A dust devil may last just a few seconds to several hours. A dust devil will pick up in speed with wind speeds as high as 100 km/h. The dust devil will pick dust, dirt, leaves, objects which enable you to be able to spot the dust devil.

Ideal Weather Conditions

Dust devils can be destructive as they lift dust and other debris into the air. Small structures can be damaged, and even destroyed, if in the path of a strong dust devil. If you were to do greenhouse farming of the valuable cut-flowers near a lake and you get the ideal weather conditions for dust devils, then the destruction to your flowers by dust devils may be a common risk to take care of.

Whatever man can not understands he consults witchcraft. Today, does man understands the electrical characteristics of dust devils?

      Hi, Iphigenia. How is Boulogne Billancourt?  At about 8 degrees celcius, you must be freezing.  You may have a tall order of being able to spot at least the smallest dust devils (about half a meter wide and 1 metre tall) in France during the months of July and August when you get high temperatures of 24 degrees Celsius. But if you go to Sahel you will be able to see all sizes of dust devils. A dust devil is usually harmless and will not destroy your terrace.

      Interesting stuff - as with another hub of your i have learned about something that is completely alien to me never heard of this phenomenon before. Where I live we get 2 strong winds - the Mistral which cuts up along the coast to us from Marseille and really messes with the stuff on my terrace and the Sahel which blows from nrthern africa and drops red sand all over everything on my terrace - a dust devil would just about finish my terrace off !

      Thank you, Ralph Deeds. Dust devils, tornadoes and waterspouts have a lot of similarities but each has a different science. And it is In the Arizona desert of USA that one can be able to find some of the largest dust devils in the world.

      Hi, Aya Katz. Yes, Dust devils are very common in dry desert-like conditions but also anywhere else where air temperatures are above 25 degree Celsius, relative humidity is under 30 percent and wind speeds of under 10 knots. However, they should not be confused with sand storms.

      Great video. I've seen smaller ones in the Arizona desert between Phoenix and Tucson. And I once saw a water spout on Lake Erie. Are waterspouts the equivalent of dust devils. At the time I thought I was seeing a tornado. It was a very hot and windy 4th of July weekend marked by high winds and thunderstorms.

      Ngureco, thanks for this informative hub on dustdevils. Do they occur primarily in dry, desert-like conditions?
