Notes:
|
This table summarizes the various formats used for numbers assigned to tropical (and sometimes subtropical and potential tropical) cyclones (regardless of intensity or naming status) by various weather forecast centers; these numbers are called tropical cyclone numbers (TC numbers for short)), cyclone numbers, cyclone IDs, storm IDs, etc. depending on the weather tracking center. Note that not all centers prefix or suffix their numbers (most often locally), sometimes leading to ambiguity when discussing such numbers outside their corresponding basins. Warning centers above in bold are those officially tasked by the World Meteorological Organization (WMO) to monitor and issue warnings in their corresponding basins; those in italics (like JTWC) monitor and issue warnings on an unofficial basis, mainly to certain diplomatic and/or military interests.
Usage
This template takes up to three optional parameters:
{{Tropical cyclone numbering|width|float|class}}
- Default table width is
width=57%
, but can be overridden with other values likewidth=35%
(which simulates its look in mobile view, depending on platform). - Default float mode is
float=none
, but can be overridden with any other value likefloat=left
andfloat=right
. - By default, the collapsible table is set to display in full, with only the Notes list on the bottom row collapsed. If it is desired to collapse the table by default on an article page (like "Tropical cyclone"), then
class=mw-collapsed
may be provided as a parameter.
Width and float settings affect only desktop view; they are ignored for mobile view. Also, the class=mw-collapsed
setting affects only desktop browser view and the Wikipedia mobile app; it is currently ignored for mobile view in mobile browsers.
