What are massive Dust storms?
Only two factors come to mind when it comes to dust “storms.” But first, let me define a dust storm for you: a powerful, turbulent wind that blows fine particles, dirt, and sand across a vast region.
What causes Dust storms?
Winds behind a cold front or within a strong high-pressure system are the primary reason… As a front is the leading edge of a high, and all the air behind the front is the high itself, these may be the same thing. When this blows over dry soil and dust, it may create massive “fronts” of dust that travel enormous distances in a short amount of time.
The second factor, which I’ve personally witnessed, is thunderstorms collapsing or organizing. The air rushes down to the earth and spreads forth as the storm approaches. In places like Arizona, the region around storms is usually dry and parched, as the rain usually falls solely on the mountains. This causes the dust to rise once again. In comparison to frontal dust storms, the ensuing “dust storm” is generally more wall-like and frightening, but slower-moving and shorter-lived.
-Dust storms are not to be confused with sand storms, which may occur in a variety of locations and for a variety of reasons.
How do dust storms start?
In general, heavy winds and warmth can cause dust to be kicked up, but I believe you’re referring to haboobs.
When a thunderstorm occurs in a dry region (desert), the rain evaporates before it reaches the ground. During this process, the air cools by around 30 degrees Fahrenheit, making it heavier than the air surrounding it. As a result, it sinks quickly.
When it strikes the ground, it spreads out, but instead of spreading out, it creates a circular pattern, similar to a wheel, rotating in the opposite direction of the wind blow.
The leading edge is rising, the trailing edge is lowering, and the bottom is moving twice as fast as the dust wall. You can notice this if you vape and blow a cloud on the ground. This pushes up a lot of dirt, which is then lifted into the air.
How bad are massive dust storms?
Dust storms in the form of haboobs occur frequently here, so I can speak from personal experience.
Direct concerns to the body, like having grit in your eye or particles in your lungs, occur and are unpleasant, but they are not the most serious risks offered by dust storms, at least not in industrialized places.
High winds and poor visibility make it risky to be outside. During dust storms, flying debris and car accidents (induced by reduced visibility) injure more people than the dust storm itself.
How to avoid massive dust storms?
They’re bad if you’re outside. They are inconvenient if you are indoors.
“Dust Storm Safety Recommendations” If you see dense dust blowing over or approaching a road, pull your vehicle off the road as far as feasible, stop, switch off lights, set the emergency brake, and lift your foot off the brake pedal to make sure the tail lights are not lighted. If at all possible, avoid entering the dust storm region. If you can’t get off the road, drive at a safe pace, switch on your lights, and honk your horn intermittently. Use the painted middle line as a reference point. Locate a safe spot to pull off the road. Never pull over to the side of the road if it’s busy.
What to do during a dust storm?
During a dust storm, be safe by doing the following:
- Try to stay as much as possible indoors.
- Ensure that all windows, doors, and vents are closed.
- Cover your mouth and nose with your hands.
- Wearing a dust mask to keep dust out of your eyes.
- While driving, keep an eye out for unexpected changes in vision.
- When driving in windy weather, avoid driving since windblown dust is more likely.
- As a safety measure, I’m pulling over and turning on my headlights.
