This is the {{ Storm index}} or storm index article template.
It can be used to mark a page as a set index article about named storms. A storm index article lists multiple storms, preferably with a description of their date and location.
This template is usually placed at the bottom of the page and adds the page to Category:Set index articles on storms.
This template can be used without any parameters like this:
{{Storm index}}
Editors may want to control how the page is sorted in
Category:Set index articles on storms.
This is accomplished by adding the
sort key as the "name=" parameter.
For example,
List of storms named David is sorted using:
{{Storm index|name=David}}
or, in short:
{{Storm index|David}}
