"Advective (horizontal) motion is due entirely to air replacing that carried aloft by convection, is a languorous process at best."
Note that the second 'is' is superfluous; the 'is' following the word 'motion' is the verb in the sentence. This sentence is correct as it currently stands in the article.

[edit] ITCZ and/or ITC?
I'm working on the German Article and there some Questions:
- ITC - Inter Tropic Conversion
- ITCZ - InterTropical Convergence Zone
- ITC - Inner Tropic Conversion
- ITCZ - InnerTropical Convergence Zone
HEy i love you!:: Shouldn't the words of title of the article be all capitalized (because it would be Intertropical Convergence Zone)? I doubt that only the I is capitalized (as it currently stands in the first sentence of the article). --AySz88^-^ 17:12, 10 December 2005 (UTC)

- Yes, the article title is incorrect, but I cannot get it to accept the change as the software for moving articles does not distinguish between Intertropical convergenze zone (incorrect) and Intertropical Convergence Zone (correct). - Marshman 00:05, 5 January 2006 (UTC)

[edit] Some changes of mine...
I changed [1]:
- It is formed, as its name indicates, by the convergence of warm, moist air from the latitudes above and below the equator.
to
- It is formed by the vertical ascent of warm, moist air from the latitudes above and below the equator.
I think the latter is correct: if it were formed by convergence (for whatever reason) it would be a *high* pressure area. Its a *low* pressure area because the ascent is effectively sucking air in.
I also changed:
- Because of the strength of the Hadley cells on either side of it, weather systems familiar to mid-latitude dwellers do not have the chance to form, and as a result, there are no prevailing winds. Advective (horizontal) motion is due entirely to air from the trade winds replacing that carried aloft by convection, a slow, languorous process at best.
to:
- Within the ITCZ the average winds are slight, unlike the zones north and south of the equator where the trade winds feed in.
I don't think the former is correct. You don't get traditional mid-latitude weather systems in the tropics because (a) the coriolis effect is different and (b) the forcing is different too (which gets into yucky why-is-the-ferrel-cell territory). The key point is that in the trades, there are steady winds which are the hadley cell inflows. Directly under the updrafts, this inflow stops and thats why there are doldrums: it *isn't* anything to do with the strength of the hadley circ.
OK, thats my take, discussing as promised. Over to... William M. Connolley 21:58, 15 May 2006 (UTC)
[edit] Question
How significant is the ITCZ to the formation of tropical cyclones? It obviously has something to do with them, else the NHC would not bother mentioning it in their tropical weather discussions. However, I don't know how important its influence is (hence the low TC importance) and this article does not clarify that situation at all.--Nilfanion (talk) 09:44, 12 June 2006 (UTC)
[edit] Question
I heard in highschool that this region was also referred to as The Horse Lattitudes because Spanish vessels that traveled to the New World and got caught in this belt would dump their horses overboard to lighten their load to hopefully pick up speed. Any word on the truth of this? Improvclifton 9:00, 12 July 2006 (UTC)
[edit] low spirits?
"Within the ITCZ the average winds are slight, unlike the zones north and south of the equator where the trade winds feed in. Early sailors named this belt of calm the doldrums because of the low spirits they found themselves in after days of no wind. To find oneself becalmed in this region in a hot and muggy climate could mean death in the era when wind was the only motive force."
doldrums has two meanings in the dictionary:"a state of inactivity or stagnation, as in business or art" and "a dull, listless, depressed mood; low spirits." Why is only the low spirits reason listed for the naming of the area, wouldn't the first definition fit better?
also, there is no reference backing that section up

[edit] Importance
Raised to high importance, simply because this is the intertropical convergence zone we're talking about here. --Coredesat talk. o_O 18:49, 11 September 2006 (UTC)
