- List of unnamed tropical cyclones
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 occurred in all basins and for various reasons.cope, reasons, and naming overview

Christopher Landsea |title=Subject: B1) How are tropical cyclones named?|format=FAQ|accessdate=2008-05-05] tropical cyclones are named when, according to the appropriateRegional Specialized Meteorological Center orTropical 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:* Post-operational upgrading. An example of this is the Unnamed tropical storm from the
1996 Pacific hurricane season .cite web|url=http://www.nhc.noaa.gov/1996unnamed.html|title= [U] nnamed tropical storm(formerly Tropical Depression One-E)|author=Edward Rappaport |date=1996-11-07|accessdate=2008-05-05|publisher=National Hurricane Center ]
* Being missed during a season. An example of this is the2005 Azores Subtropical storm from the2005 Atlantic hurricane season .cite web|url=http://www.nhc.noaa.gov/pdf/TCR-AL212005_Unnamed.pdf|format=PDF|date=2006-04-10|author=Jack Beven & Eric S.

Naming has been used since the 1950 season.

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.
Eastern and central north Pacific Ocean
Naming began in 1960. Before 1957, a few systems in the central Pacific basin were given names, generally in an ad hoc manner.
*Tropical Storm 4 - 1962
*Tropical Storm 8 - 1962
*Tropical Storm 4 - 1963
*Hurricane 12 - 1975
*Tropical Storm 1 - 1996Western north Pacific Ocean
Due to differences in wind speed criteria between the
Japan Meteorological Agency and theJoint 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 apparent 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.* Tropical Storm 6 - 1995
* Tropical Storm 17 - 1996
* Tropical Storm 26 - 1996
* Tropical Storm 29 - 1996
* Tropical Storm 2 - 1998North Indian Ocean
Due to differences in wind speed criteria between the
India Meteorological Department and theJoint 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 apparent 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.cite web|url=http://www.webcitation.org/5QzqpfB7g|title=Mid-Season Review|publisher=
