The list of unnamed tropical cyclones since naming began includes all tropical cyclones that met the criteria for naming in a basin, but that for whatever reason, did not receive a name. These systems have occured in all basins and for various reasons.

Further information: Tropical cyclone naming

In order to ease communications and advisories,[1] tropical cyclones are named when, according to the appropriate Regional Specialized Meteorological Center or Tropical Cyclone Warning Center, tropical storm status. A tropical cyclone with winds of tropical storm intensity or higher goes unnamed when operationally, it is not considered to have met the criteria for naming. Reasons for this include:

The unnamed tropical storm from 1987
The unnamed tropical storm from 1987

Naming has been used since the 1950 season.

[edit] Subtropical cyclones

Only unnamed subtropical cyclones that could have been named are included. This excludes several that existed, but that were unnamed because subtropical cyclones were not named when they existed.

Naming began in 1960. Before 1957, a few systems in the central Pacific basin were given names, generally in an ad hoc manner.

[edit] Western north Pacific Ocean

Due to differences in wind speed criteria between the Japan Meteorological Agency and the Joint Typhoon Warning Center, a system will sometimes be considered a tropical storm by the JTWC but only a depression by the JMA. This results in several apparant unnamed systems. Because the JMA is responsible for naming, "unnamed tropical cyclones" that met the JTWC's tropical storm criteria but not those of the JMA are excluded.

[edit] North Indian Ocean

Due to differences in wind speed criteria between the India Meteorological Department and the Joint Typhoon Warning Center, a system will sometimes be considered a tropical storm by the JTWC but only a depression by the IMD. This results in several apparant unnamed systems. Because the IMD is responsible for naming, "unnamed tropical cyclones" that met the JTWC's tropical storm criteria but not those of the IMD are excluded.

Naming has taken place since 2006.

There have been no unnamed tropical cyclones using the India Meteorological Department's criteria. One system, 2007's Yemyin, was upgraded after the fact and retroactively named.[4]
