Talk:Occluded front

Long lost article
In looking for articles that were stated to redirect to surface weather analysis, I found this article. Recently, a weather front article was split off from surface weather analysis and is being placed for GA. The question is, does this article need to become a redirect, or do people want to really work on this article separately, now that is has been found?

symbols
I have never ever seen purple symbols on any weather forecast.

The Met office are professionals. They know what they are doing. They use red and blue colours for occluded fronts on all of the BBC weather forecasts. NOT purple.

Right now on this page - http://www.bbc.co.uk/weather/2643567 I can see loads of occluded fronts and they are red and blue and point in the same direction. Look at maps further down the page and select pressure. — Preceding unsigned comment added by 81.143.36.93 (talk) 22:56, 6 December 2012 (UTC)

Here we have some exam revision and it mentions that you can have red and blue - or you can have purple. http://www.bbc.co.uk/schools/gcsebitesize/geography/weather_climate/weather_systems_rev2.shtml

This page from the met office says purple http://www.metoffice.gov.uk/education/teachers/in-depth/understanding  — Preceding unsigned comment added by 81.143.36.93 (talk) 23:06, 6 December 2012 (UTC)


 * I've added red and blue as an alternative to purple; red and blue does seem more common on Met Office and the BBC but clearly both sets (purple and red-and-blue) are used. This - and the article as a whole - could do with more references. I'll look back if/when I get a moment, but obviously if someone else could step in in the meantime that would be excellent! 82.70.49.110 (talk) 10:39, 23 July 2013 (UTC) (No connection to the original or subsequent posters).

I have used purple for occluded fronts for over 40 years. I served in the USAF Air Weather Service during this time. Maybe it is only a US thing and the Brits don't use purple? — Preceding unsigned comment added by 167.95.29.43 (talk) 18:19, 21 January 2016 (UTC)

Better Dynamics Needed
This is not my article so I wont add to it. The article has been written by a local area forecaster, ie has no real knowledge of formal dynamics. Occlusion process belongs to the subject of frontogenesis, and is a product of the unlocking of geostrophy by a baroclinic instability. The colder air flows isalobarically (as Gill calls it) into the cyclone center, at ground level, simply because it is the densest. This converts the potential energy trapped by geostrophy into kinetic energy. These systems can persist for a matter of tens of hours, but eventually the half-pendulum-day will catch up with it.203.213.63.24 (talk) 23:51, 13 October 2014 (UTC)


 * maybe so, but neither of your explanations are anything other than complete blather to someone who is trying to learn about weather. if you want to teach something, at least try to make it comprehensible jeaze louise. 76.167.208.75 (talk) 06:39, 19 November 2022 (UTC)
