Template:Short description 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.

The unnamed subtropical storm 01L in the north Atlantic in 2023

Naming has been used since the 1950 season. 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, it has reached 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:

North Atlantic Ocean

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.

South Atlantic Ocean

The South Atlantic is not officially classified as a tropical cyclone basin by the World Meteorological Organization and does not have a designated regional specialized meteorological center (RSMC) that gives official names to tropical cyclones. Despite this, in 2011, the Hydrographic Center of the Brazilian Navy began giving unofficial names to tropical and subtropical cyclones in the south Atlantic. Prior to that, a few systems in the south Atlantic were given names.

There has been one system, Tropical Storm 01Q in 2021, that was monitored and designated 01Q by the National Oceanic and Atmospheric Administration (NOAA). However, the Brazilian Navy did not recognize the system as a tropical cyclone and it remains unnamed.

Eastern and Central North Pacific Ocean

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

Western North Pacific Ocean

File:35W 1996-11-02 2100Z.png
The unnamed tropical storm 35W in 1996

The official practice of tropical cyclone naming started in 1945 within the western north Pacific.[13][14] 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, or vice versa. This results in several apparent unnamed systems. Prior to 2000, the JTWC was responsible for tropical cyclone naming, with the JMA assuming responsibility for naming from 2000 and beyond. Due to this, unnamed cyclones that met the JMA's tropical storm criteria but not those of the JTWC prior to 2000 are excluded. Likewise, systems that met the JTWC's tropical storm criteria but not those of the JMA from 2000 to present are also excluded.

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 apparent unnamed systems. Because the IMD is responsible for naming, unnamed cyclones that met the JTWC's tropical storm criteria but not those of the IMD are excluded.

Naming has taken place since mid-2003.

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.[15]

South-West Indian Ocean

Tropical cyclones have been named within this basin since 1960, with any tropical or subtropical depressions that RSMC La Réunion analyze as having 10-minute sustained windspeeds of at least 65 km/h, 40 mph being named. However, unlike other basins RSMC La Réunion does not name tropical depressions, as they delegate the rights to name tropical cyclones to the subregional tropical cyclone warning centers in Mauritius or Madagascar depending on whether the system is located east or west of the 55th meridian east.

Notes

<templatestyles src="Reflist/styles.css" />

  1. Was deliberately left unnamed to avoid any confusion as the news media was focused on the Perfect Storm and was expected to be short-lived and primarily of concern to maritime interests.[6]
  2. a b Subtropical storms were not given names prior to 2002. However, since this system was recognized post-operationally it is included in this list.
  3. Advisories were not issued on this system during August/September 2011 because of the intermittent nature of the convection and the somewhat frontal nature of the satellite presentation.[8]
  4. This system was upgraded from a tropical depression to a tropical storm after a letter from a ship called the Golden State prompted a re evaluation of the system.[9]
  5. This system was upgraded from a tropical depression to a tropical storm after a ship called the Richfield reported sustained winds of Script error: No such module "convert"..[9]
  6. This system was not named or numbered as a tropical cyclone operationally, but has been recognized as an unnamed tropical storm since.[10]Template:EPAC hurricane best track
  7. Was upgraded from a tropical depression to a tropical storm after the United States Coast Guard relayed ship reports to the National Hurricane Center, that suggested the cyclone was a tropical storm.[11]
  8. Was upgraded from a tropical depression to a tropical storm after European Space Agency's Advanced Scatterometer (ASCAT) suggested that the cyclone was a tropical storm.[12]
  9. Was upgraded from a tropical depression to a tropical storm after European Space Agency's Advanced Scatterometer (ASCAT) suggested that the cyclone was a tropical storm.Script error: No such module "Unsubst".
  10. Was operationally classified as a depression by both the JTWC and PAGASA, the latter of which named the system Ningning. However, it was later determined by JTWC that the system reached tropical storm intensity.
  11. Could not be named during February 1997 as it had developed into a tropical cyclone within the subtropic region of the Southern Pacific.[4][5]
