(concerning the merge tag) Just my two cents, but I think troughs have enough importance to keep their own article, and should not be merged with Surface weather analysis. EWS23 (Leave me a message!) 05:47, 23 September 2006 (UTC)[reply]

Pictures, Additional Troughs

Perhaps we could get some graphical representations of each kind. Also, we can't forget surface troughs! ~ Triberocker (talk) 21:37, 20 February 2008 (UTC)[reply]

Nice diagram of a trough but the axes need labeling -TF —Preceding unsigned comment added by 210.4.229.99 (talk) 00:45, 27 August 2009 (UTC)[reply]

Weather newbie here. In looking at the first illustration I *think* I am looking at a cross section of the atmosphere facing north somewhere above the equator. But if that's true, it's really not easy to discern. It would benefit from some additional "context" like compass markings, altitude markings, maybe something like "the ground". Just a thought, but I think it'd make the thing quite substantially easier to understand. SVDasein (talk) 16:34, 19 February 2011 (UTC)[reply]

I think its supposed to be a top-down view, i.e. as would be depicted on a weather chart (with north at the top of the image). The long, sinuous line is (I think) meant to represent an isobar (ridges and troughs are so-called because when charted, the isobars around them resemble the contour lines around physical ridges and valley on a topographic map). That really needs to be said in the article (if someone can find a cite for it), and the graphic needs to be better labled (or replaced entierly). Wardog (talk) 14:15, 29 March 2011 (UTC)[reply]

Hello. I have not used a talk page before, so apologies for any technical gaffs here. I would like to suggest to expert authors/editors in the field of meteorology that - quite in general (i.e., not just for the present article) - it would be very helpful to non-experts to always find, in all diagrams of physical phenomena, an indication of the relevant 2- or 3-D coordinate system. There are many interesting evolutions that could be happening in either the horizontal or vertical directions (or both); I often find myself confused without coordinates. Thank you.

Wording: "crosses" or "lies/stretches across"?

In the article, part of the caption under a satellite picture reads: "A very large trough (about 8000 km or more) crosses the North Atlantic Ocean from north east to south west." The verb "to cross" suggests (at least to me; and refer to https://en.wiktionary.org/wiki/cross#English) a movement, and according to the suggestion in the caption, in this case it would be a motion from northeast to southwest.

As far as I know, such a direction of motion for troughs in the Northern Hemisphere is rather rare, and even more so along an 8,000 km long feature (as indicated in the caption). Therefore, I suppose what the author really meant to say: "A very large trough (about 8000 km or more) lies across the North Atlantic Ocean from northeast to southwest." The wording "stretches across" would also do, I suppose. Could the author comment to this and state the intended message?Redav (talk) 10:53, 18 February 2020 (UTC)[reply]
