Instructions for the proper application of the geographical area designator.
1. The designator specified in this table should be used to the greatest extent possible to indicate the geographical area of the data contained within the text of the bulletin.
2. Where the geographical area of the data does not correspond exactly with the designator, the designator for the area most approximating that of the data may be used.
3. When the table does not contain a suitable designator for the geographical area, an alphabetic designator which is not assigned in the table should be introduced and the WMO secretariat notified.
