Discussion Overview

The discussion revolves around a significant cyclone off the coast of Queensland, Australia, focusing on its predicted track, naming conventions for cyclones in different hemispheres, and related weather impacts in New Zealand. The scope includes meteorological observations and regional naming practices.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant shares the predicted track of the cyclone and provides a source for satellite imagery.
  • Another participant questions the naming conventions for cyclones in the southern hemisphere compared to the northern hemisphere, specifically in the Pacific basin.
  • A subsequent reply notes uncertainty about the naming authority and mentions that the cyclone in question was not named by the Australian Bureau of Meteorology due to its origin outside local waters.
  • There is a mention of potential bad weather in New Zealand as a result of the cyclone's activity.
  • A participant expresses interest in the US Navy's tropical cyclone page as a resource for further information.

Areas of Agreement / Disagreement

Participants express uncertainty regarding the naming conventions for cyclones and the specific agencies responsible for naming in different regions. There is no consensus on these points, and the discussion remains open-ended.

Contextual Notes

Limitations include the lack of clarity on the specific naming authorities for cyclones and the conditions under which they are named, as well as the geographical scope of naming conventions.

CW rotation no less.:wink: Oma? Names in southern hemisphere are same or different than northern for the "Pacific" basin?

Good question, I am not sure who does the naming.
Since this one originated 2000km or more to the NE, it would not have been named by the Australian BOM
as they will only name ones formed in the regions local to Australia.

EDIT: this is informative ... different Pacific regions, different agencies ...
