A new study suggests that severe storms are likely to start affecting wider areas that include cities like New York, Boston, Beijing and Tokyo.An international research team predicts that big atmospheric storms called tropical cyclones could move further to the north or south.It said this is because of the effects of planet-warming climate change.The U.S. National Oceanic and Atmospheric Administration describes tropical cyclones as "organized systems of clouds and thunderstorms" that develop over bodies of water.Major tropical cyclones are declared either hurricanes or typhoons, depending on where the storms happen.In the North Atlantic, central North Pacific and eastern North Pacific, the term hurricane is used.In the Northwest Pacific, the storms are called typhoons.The researchers suggest that hurricanes and typhoons could start appearing farther north in the northern half of the world and farther south in the southern half of the world.
