• Drought conditions cause fewer tornadoes, not dust devils


    (FOX 25 / MyFoxBoston.com) – Drought conditions may have been eased in the Northeast with spring rains, but the drought rolls on in other parts of the country.

    One benefit of having little rain is that there are fewer tornadoes and thunderstorms. 

    Tornadoes need moisture to form, but a cousin of the tornado, the dust devil, certainly does not.

    Extreme heat and drought conditions have created perfect dust devil conditions in Alice Springs, Australia.

    A dust devil, also known as a fire whirl, is made when hot air rises rapidly and is hit by winds that make it turn just right. If that column of air runs into a fire, a dust devil is the end product.

    Dust devils can be dangerous, but this particular one occurred in an unpopulated area in the outback.

    Dust devils are common in desert regions, but these "fire tornadoes" are something that firefighters must watch for when battling huge brush fire that can be seen in the Western United States.
