The content of this page would be a useful addition to the page on Tides. Inaspicious (talk) 20:01, 14 February 2009 (UTC)[reply]

I have a concern over plagarism. The second paragraph of this article was lifted directly from a NOAA information page on the same topic. I'm not entirely sure this is legal. You can see the NOAA original here:

Effect of the Sun[edit]

The Sun has a similar gravitational effect on the tides as the Moon. Perigee of the Sun occurs during the winter when the tide range increases above normal. —Preceding unsigned comment added by 69.37.158.214 (talk) 18:59, 2 December 2009 (UTC)[reply]

While the Earth is indeed closer to the Sun during (northern hemisphere) winter with perihelion currently occurring around January 4, this astronomical forcing of the tides is entirely swamped by climatological effects. The peak in the "Sa" or "solar annual" tidal harmonic typically occurs at the end of northern hemisphere summer when the Earth is still near its maximum distance from the Sun. Expansion of the oceans' waters by thermal heating is a larger effect than the astronomical forcing. 173.127.241.182 (talk) 01:29, 12 July 2012 (UTC)[reply]

King Tide[edit]

What's the difference?? Would a merge be appropriate? --BjKa (talk) 09:38, 8 December 2010 (UTC)[reply]

Terrible prose. Copied from Wood.[edit]

This line: "On March 6, 1962, a catastrophic perigean spring tide struck from the sea in the darkness of predawn, and for the following 65 hours inundated the entire Atlantic coastline of the United States from the Carolinas to Cape Cod. " is just awful prose. It's not factual information. It's some grandiose posturing copied directly from Fergus Wood's introduction to his 1978 book on "perigean spring tides". It's important to understand that Wood was obsessed with such tides, and his book was a culmination of that lifelong obsession filled with anecdotal evidence and exaggerated claims. His book may have "struck from the sea in the darkness of predawn" but that phrasing doesn't describe the weather system that hit the US, coincident with a perigean spring tide, in 1962. As noted on the NOAA web site, his book has been widely misinterpreted. But the NOAA web site does NOT point out that this misinterpretation was largely due to Wood's own "selling" oh his seriously exaggerated theories.

Confusing first paragraph[edit]

The first sentence says this tide occurs 3-4 times a year. The last sentence says it occurs once every 18 months. Both sentences can't be right. So which one is correct? Jdc843 (talk) 19:04, 23 May 2018 (UTC) 184.198.78.70 (talk) 16:31, 12 July 2012 (UTC)[reply]

Fixed Robert Walker (talk) 19:13, 23 July 2018 (UTC)[reply]

Not fixed. That's a misreading of a primary source of dubious authority (see above section) which only says that a certain astronomic cycle has a 205.89-day cycle and that some spring tides have occurred at multiples of 205.89 days; it does not say that the spring tides occur at intervals of 205.89 days and even if it did, we couldn't use it. 92.19.27.191 (talk) 16:39, 15 August 2018 (UTC)[reply]

Title[edit]

"proxigean spring tide" is cited as the primary name for this phenomenon, so why is the article titled after the "also known as" variant, "perigean"? Just seems odd. PurpleChez (talk) 14:46, 20 November 2019 (UTC)[reply]
