Tropical storms like hurricanes, cyclones or typhoons last a long time and are given names to be identified quickly.
There can be 100 storms a year and sailors need to be able to tell them apart.
The first storm of a year will have an A name, like Hurricane Alice or Typhoon Andrew, the next one gets a B name and so on.
There are regular meetings of weather scientists who decided on new names for the next year.
Names of storms which cause a lot of damage are never used again.
