An overview of the nasa satelite for the theory of intertrtropical convergence zone

After completing this section, you should be able to define Earth's "general circulation," and be able to discuss the Hadley circulation in the tropics, specifically the Intertropical Convergence Zone ITCZ and the hot towers that form along it. Astronomer Edmond Halley loved to dabble in various scientific fields of study. Inhe calculated that a bright comet he observed in the heavens was periodic and that it would return in

I saw this in the first paragraph of the article. In geography there's no such thing as Up and Down. There are North and South. Because "above the Equator" could mean "over the equator in the atmosphere", and even "on geostationary orbit".

Please be accurate and use the proper geographic concepts "to the North" and "to the South". A look at a satellite picture in July will immediately confirm this.

The image should be removed. The OIT is proposed by a number of academic scholars in the field. It has also been recently burgeoned by genetic studies done in the last 5 years. So to claim it is "rejected" by scholars is patently false, as there are some scholars who are far more knowledgeable in the field than you or I who are currrently advocating it.

Doldrums redirect[ edit ] Doldrums should not redirect here. The doldrums is a particular area of the atlantic ocean and maybe other oceans, but at any rate not any of land mass which has a particular weather pattern perhaps caused by the ITCZ but with particular history, cultural significance and maritime relevance.

To explain the term "Doldrums" in an encyclopedia purely by reference to this physical, technical description of its meteorology seems to me to miss something pretty significant.

For example, does this article capture the sense of the doldrums conveyed by Coleridge's Rime of the Ancient Mariner?

I don't think it does. A Doldrums article which I don't feel qualified to write, by the way ought to hyperlink into this article, but should all the same be separate. It's the area where sail ships had an impossibility to sail due to lack of wind.

This is precisely the opposite of what the ICZ is: Over the oceans, where the convergence zone is better defined, the seasonal cycle is more subtle, as the convection is constrained by the distribution of ocean temperatures.

I have 3 questions to this paragraph: However, the ICZ is characterised by heavy rainfall. Both the other map Omegajuly-era Since the map ITCZ january-july.

There are some more pix available from http: Sadly they don't do monthlies - seasonal stuff smears it out William M. Omega is not a good way to estimate the ITCZ position, especially if you draw it from jsut one year.

I think the original map is close to the truth, and will try to find a better "source" if I can. I'd think it would be hard to distinguish the ITCZ from storms that form spontaneously in permanent troughs caused by land patterns. Also, the pressure patterns at mb wont always line up with those on the ground.

For example, the American southwest often experiences shallow lows in summer due to the heat, but at mb it shows up as a high. In any case, I have always thought that most scientists agree that the Asian summer monsoon is considered to be an arm of the ITCZ, even when it moves very far north, and even when it becomes very dry.

If this is not so, I stand corrected I know that I've read that in sources outside of Wikipedia, though. As for the Asian monsoon - doesn't the omega pic show that? I'm not a monsoon person though so could be wrong William M.

This ITCZ article needs to be updated to describe the differing CZ terms and which part of the world they're associated with. Also, the Monsoon trough article seems to put more emphasis on the Pacific, not the Atlantic.

Per the comment in the upper part of this talk page, this move was advertised six months in advance, so it should hardly be a surprise that I followed through on the suggestion when there was no feedback to the contrary.

New evidence has surfaced from two different sources that around Australia, the ITCZ and monsoon trough are separate features, which may be the only place globally that this is the case. If we go with the preface that active portions of the ITCZ are known as the monsoon trough, then technically the quiet ITCZ is not responsible for TC genesis, but that the active monsoon trough portions are.Convergence develops near the latitude at which this balance occurs.

Tomas, Holton, and Webster hypothesize that this convergence defines the location of the eastern Pacific ITCZ, which is the rising branch of the cross-equatorial Hadley circulation. Satellite data, however, has confirmed that there is an ITCZ north of the equator and a parallel ITCZ south of the ashio-midori.comion in the location of the ITCZ is important to people around the world because it affects the north-south atmospheric circulation, which redistributes energy.

The Eastern Pacific ITCZ during the Boreal Spring Guojun Gu, Robert F. Adler and Adam H. Sobel Popular Summary The intertropical convergence zone (ITCZ) 1~ a narrow band of tropical convection am rainfall in the Pacific and Atlantic, generally staying in the north hemisphere.

The Intertropical Convergence Zone (ITCZ) is defined as the region where the opposing trade winds from each hemisphere meet. Due to surface convergence and strong vertical motions, the ITCZ is characterized by cloudy, rainy conditions. It is important to remember that climate sensitivity is determined by the accumulated effects of competing climate feedbacks.

For example, in addition to showing the future climate solar warming zone, Fig. 3 shows a zone of strong solar cloud radiative cooling, located between 50° and 80°S. Satellite data, however, has confirmed that there is an ITCZ north of the equator and a parallel ITCZ south of the equator.

Variation in the location of the ITCZ is important to people around the world because it affects the north-south atmospheric circulation, which redistributes energy.
