Large scale?

What does "large scale" mean? The size of a typical Kansas tornado, ten times as large, a hundred? --Vaughan Pratt (talk) 19:18, 20 July 2008 (UTC)[reply]

Synoptic scale. A wikilink has been added so people can explore what that means. Thegreatdr (talk) 01:05, 25 February 2012 (UTC)[reply]

Ozone depletion references?

Since the role of CFCs and other factors is still uncertain, some references in this section would be useful. As would fair representation of research showing other factors influencing the ozone 'hole'. — Preceding unsigned comment added by 174.61.210.61 (talk) 22:31, 29 September 2011 (UTC)[reply]

Added references. Thegreatdr (talk) 01:03, 25 February 2012 (UTC)[reply]

Technically Polar cyclones are the transitions of low pressure areas between Aleutian low and Icelandic low, as far as I can see. Some meteorologist may confirm this. Moved the Polar cylone in the template to the annual cyclones section as there is a clear annual rythm of changes with these. How they'll react to the disappearance of the arctic ice is still an unresolved question (ref to nasa image of the day (http://earthobservatory.nasa.gov/IOTD/view.php?id=78808)

Disappointingly, recent (early January 2014) news reports ^[1] have gotten the polar vortex exactly backwards, saying it's strengthened (and that's the cause of the brutal cold experienced in the US). This may produce some invalid edits of this article.drh (talk) 14:03, 6 January 2014 (UTC)[reply]
