==System identification==

Systems within ATCF are identified with the basin prefix (AL – North Atlantic Ocean, CP – Central North Pacific Ocean, EP – North-East Pacific Ocean, IO – North Indian Ocean, SH – Southern Hemisphere, SL – South Atlantic Ocean, WP – North-West Pacific Ocean) and then followed by two digit number between 01 and 49 for active tropical cyclones,<ref name="Navy">{{cite web|url=http://www.nrlmry.navy.mil/atcf_web/docs/database/new/abrdeck.html|title=Best Track/Objective Aid/Wind Radii Format|date=2010-06-08|access-date=2014-06-20|author=[[United States Naval Research Laboratory]]–[[Monterey, California|Monterey]], Marine Meteorology Division|publisher=[[United States Navy]]|archive-date=2017-11-06|archive-url=https://web.archive.org/web/20171106132459/https://www.nrlmry.navy.mil/atcf_web/docs/database/new/abrdeck.html|url-status=dead}}</ref> which becomes incremented with each new system, and then the year associated with the system (ei.ge.
