Wikipedia:WikiProject Weather/Weather by year criteria

This page is to list and explain the criteria needed for ‘Weather by year’ articles timeline.

Criteria

To be included in the timeline, a weather event must pass one, but not all, of these criteria:

1. A death occurs that can be identified as a death from the weather event and not a death that happen to occur at the same time.
2. The event has an individual article dedicated to it. These individual articles do not include list articles like Tornadoes of 2021. An individual article is like the 2021 South Moravia tornado.
3. A weather record was broken. Examples of records broken can include new record temperatures (Hot or cold) and new record precipitation (rain, snow, or ice).
4. If it is a “first time after 20+ years”. For example, the Weather of 2021 article lists Cyclone Seroja making a landfall in Western Australia Mid West region, which is the first landfall there since 1999.

Even if an event passes one of these criteria, it does not guarantee inclusion into the timeline list. Editors are welcome to be bold and add entries that pass one of these criteria, but if an addition is removed, please start a discussion on the articles talk page and let others give their opinions on inclusion of that event.

More specific details

This section will include some extra notes and possible criteria for weather events.

Tornadoes

• Deadly tornadoes, that are not part of a tornado outbreak unique article, are considered notable for the list. (Example is the Fultondale Alabama tornado.)
• If a death occurs during a tornado outbreak, do not separately list the tornado as a new entry. (Example is the tornadic deaths from the Tornado outbreak of March 16–18, 2021).
  • The exception to this note is if that deadly tornado has a subsection dedicated to it in the tornado outbreak article. (Example is this tornado in Nashville during the Tornado outbreak of March 2–3, 2020. That tornado has a subsection dedicated to it in the tornado outbreak article, so it can be considered notable enough for inclusion.)

Anticyclonic tornado

• Most anticyclonic tornadoes will be considered notable enough for inclusion. Discussions may occur on talk pages to discuss specific entries, but most will be consider notable due to the rarity of them.

Fire tornadoes

• If a fire tornado has a tornado warning issued for it, it is considered notable for inclusion.

Tropical Cyclones and Extratropical Cyclones

• If a tropical cyclone (or extra tropical cyclone) forms from a notable weather event, but itself as a tropical cyclone, is not notable enough for inclusion, then it does not receive an individual entry, but will be mentioned in the notable entry. (Example is when the October 2021 nor'easter became Tropical Storm Wanda. The nor'easter was notable for inclusion, but Tropical Storm Wanda was not notable enough for inclusion. So the entry read "The October 2021 nor'easter, which eventually became Tropical Storm Wanda...")

Wildfires

• A wildfire is NOT always considered notable for inclusion if it has a unique article.
• A wildfire is notable for inclusion if it has injured or killed people.

Microbursts

• Documented microbursts should be listed as they do not occur often. (See List of microbursts.)

Space weather

• Space weather events can be included if document disruption or problems occur to humans and if the Space Weather Prediction Center (SWPC) issues a warning.
