Tornadoes have been observed on every continent except Antarctica; however, most of the world's tornadoes occur in the United States. Other areas which commonly experience tornadoes include New Zealand, western and southeastern Australia, south-central Canada, northwestern and central Europe, Italy, south-central and eastern Asia, east-central South America, and Southern Africa

A tornado is a very powerful twisting windstorm. It is a very intense cyclone. Tornado winds are the most violent winds that take place on Earth. They are a circulating funnel cloud that comes down from a dark mass of clouds. Some of these funnels do not reach Earth. However, other funnels come down, touch ground, go back up, and touch down again.
A tornado is called a twister in some places. Most tornadoes last less than an hour. They can travel about twenty miles, at a speed of ten to twenty-five miles per hour. Some of them last several hours. These are the most destructive. They travel about two hundred miles at a speed of sixty miles per hour. Most form along a front between cool dry air from the north, and warm humid air from the south. The violent circulating winds destroy almost everything in its path. Tornado
The air pressure at the bottom of the funnel of swirling air is extremely low. When this low pressure area touches the ground, it acts like a giant vacuum cleaner. Some tornadoes even occur over water. A tornado over a lake or ocean is called a waterspout.
Tornadoes are dangerous, funnel-shaped storms that cause destruction when they come down to the ground. The winds in a tornado can be as high as 200 miles per hour - which is about three times as fast as a car on the freeway! The winds can be so strong they blow houses apart. Getting underground is the best thing to do in a tornado
The diameter of an average tornado is only about .4 kilometers. The length of a tornado's path varies, but it averages 6 kilometers. The speed of the funnel winds themselves is often placed at more than 480 km/hr ( that's more than 300 mph) although speeds of more than 800 km/hr (500 mph) have been estimated for extremely strong storms. Tornadoes generally last only a few minutes, but because they are so concentrated, they are intensely violent and dangerous storms. Roofs and walls of buildings may be blown out by the winds. houses, railroad cars, automobiles, and even people may be picked up and thrown hundreds of meters.
The greatest incidence of tornadoes is generally assumed to be North America, and especially in the Mississippi Valley. On an equal area basis, however, other countries, such as Italy, New Zealand, and the United Kingdom, exceed or at least challenge the incidence rate of the united States. In actual numbers observed, Australia ranks second to the United States. The United States is notable for the incidence of severe tornadoes of scale 4 or 5.
Tornadoes occurring in the tropics are usually extremely weak and often begin as waterspouts.
The Stockholm, Sweden and Saint Petersburg, Russia areas appear to be the northernmost regions that experience tornadoes. Tornado Tornadoes

SCABIES need people with experience?
ja
People with experience, What were your steps in getting rid of it? Did you treat once or twice with permetherin cream? And did you do it scalp down or neck down? I've read everything I can online and talked to many dermotologists many times. They just say wash in hot and that's it. Step by step what did you do? I'm also pregnant, I need this gone before my baby is due in march. I've treated for it and thought I was cured but it came back . Please help
Answer
This is information from a site here in New Zealand:
"Scabicides are chemical insecticides used to treat scabies. Those available in New Zealand include:
25% Benzyl benzoate lotion, applied daily for 3 days
5% Permethrin cream, left on for 8-10 hours
0.5% Aqueous malathion lotion, left on for 24 hours
Gamma benzene hexachloride cream is no longer recommended because of resistance and potential toxicity. Sulphur and crotamiton were popular in the past but are relatively weak scabicides.
The scabicide has to be applied before bed to the whole body from the chin to soles. The scalp and face also need to be treated in children under 2 years, those confined to bed, and some others with reduced resistance.
A repeat treatment with scabicide a week to 10 days after the first one is often recommended. It should not be repeated for several weeks after that without medical advice. Overuse of insecticides will irritate the skin and may cause cause contact dermatitis.
Each treatment with scabicide should be followed the next morning by hot-wash laundering or dry cleaning of sheets and pillow cases and any clothes worn against the skin over the last week. Non washable items should be sealed in a plastic bag and stored above 20° C for one week. Alternatively they can be frozen below -20° C for 12 hours. Rooms should be thoroughly cleaned with normal household products. Fumigation or specialised cleaning is not required. Carpeted floors and upholstered furniture should be vacuumed and all areas cleaned with normal household products. The vacuum bag should then be discarded and furniture covered by plastic or a sheet during treatment and for 7 days after.
Scabies itch usually improves within a few days of scabicide treatment but it may take 4-6 weeks for the itch and rash of scabies to clear completely because of dead mites at the skin surface. These will be slowly cast off.
To reduce the risk of the scabies treatment failing:
Ensure the scabicide is applied to the whole body from the chin down.
Leave it on for the recommended time and reapply it after washing.
Apply the scabicide under fingernails using a soft brush.
Obtain antibiotics from your doctor if there is crusting and secondary infection.
Ensure all close contacts are treated whether or not they are itchy.
A rash may persist after scabies treatment. Reasons for this include:
Scabies nodules may take several months to settle down. They are not infectious. A topical steroid may help; apply it accurately to each bump.
The scabies can result in dermatitis. Dermatitis can be due to the mite, the scratching, the treatment or other factors. Persistently itchy patches should be treated with frequent applications of emollients and mild topical steroids once or twice daily.
The diagnosis may be incorrect. Scabies can be confused with a number of other skin conditions, particularly dermatitis and papular urticaria. If you have an itchy rash, your doctor may treat you for scabies âjust in caseâ, even when it is more likely you have another skin disorder. This is because it is important to treat scabies vigorously to prevent other people catching it.
Resistance to treatment. Scabies occasionally appears to be resistant to the prescribed scabicide. Obtain advice from your doctor; a different scabicide or other treatment may be prescribed. You may be referred to a dermatologist."
So here is what you should do:
1. Apply the permethrin cream just before you go to sleep. Apply it from the chin down. Apply under finger nails.
2. 8-10 hours later (as soon as you wake up), have a shower at wash the cream off.
3. Do a hot-wash of all clothing and bedding. Follow the other rules above for furniture ect
4. One week later, do another treatment with the permethrin cream and another hot wash.
If you follow the above steps and it still comes back, it isn't scabies and you should see your doctor about this.
