What causes a storm to be renamed a hurricane?

Answer:

because when cold and warm air collide over the ocean they spin in a counterclockwise direction. when wind speeds reach up to 75 mph it is called a hurricane or typhoon. the difference between a hurricane and typhoon is hurricanes happen on the east coast of North America and typhoons happen on the west coast.
