Wind blowing in a spiral form around a region of low atmospheric pressure is a ______.

Wind blowing in a spiral form around a region of low atmospheric pressure is a ______.

  • (A) Tornado
  • (B) Hurricane
  • (C) Cyclone
  • (D) Tsunami
  • Cyclone is a large mass of air with strong winds that rotate around a powerful low-pressure area. The direction of the winds in the Northern Hemisphere is counter-clockwise, whereas in the Southern Hemisphere, the direction of the winds is clockwise. The word "cyclone" comes from the Greek word "kyklos," which means "circle" or "coil."
  • Tornado, hurricane, and tsunami—each is an interesting weather or ocean phenomenon, but they’re not the same thing. Tornado is a rotating column of air that comes out of a thunderstorm cloud and touches the ground, and it’s not about the large-scale low-pressure system.
  • Hurricane is an intense tropical cyclone that appears in the Atlantic or the Northeast Pacific, and while it’s the right general type of phenomenon, the more general, specific word for any rotating wind pattern with a low-pressure center is “cyclone.”
  • Tsunami, on the other hand, has nothing to do with wind—tsunami is the result of large ocean waves caused by the displacement of huge amounts of water, such as an underwater earthquake or volcanic eruption.
