Answer: Electromagnetic spectrum
Explanation: I believe this is the answer you are looking for I may be incorrect.
I did some research, and I found this: "<span>Since 1953, US started using </span>female<span> names. The practice came to an end in 1979 when the US Natural Weather Service and the World Meteorological Organisation developed a systematic way of naming </span>cyclones<span> in the beginning of the year, alternating male and </span>female<span> names, arranged in an alphabetical order."
Hope this helps you, and happy studying~!
