Warming and winds

Our world is gradually warming, but the warming is not equal everywhere. Researchers are trying to understand how the warming affects the climate in different regions, since for people the significant changes in their region are the ones that are "interesting" and they must be addressed and the immediate lifestyle adjusted.

Changes in clouds and amounts of rain over the equatorial Atlantic Ocean in the last sixty years, dark brown = 40 mm more rain per month, gray = 40 mm less rain per month, (note the increase on the West African coast)
Changes in clouds and amounts of rain over the equatorial Atlantic Ocean in the last sixty years, dark brown = 40 mm more rain per month, gray = 40 mm less rain per month, (note the increase on the West African coast)

The understanding of the regional changes is lacking because of a lack of observations and data about the wind regime over the oceans. The raw data from wind observations over the ocean showed that the winds have gotten stronger in the last sixty years, but it turned out that the data is due to the location of the measuring devices, most of the measuring devices are located on ships since the ships are faster and higher the data is skewed.

According to An article published in: Nature Geoscience, two researchers, Hiroki Tokinaga & Shang-Ping Xie International Pacific Research Center, University of Hawaii at Manoa developed a new method for removing the restraints and obtaining information and collected existing data, corrected the inaccuracy by offsetting the raw data in height and speed, combined new information and found Because in the years 1950 to 2009, as a result of warming, the trade winds weakened in the equatorial region of the Atlantic Ocean, which resulted in increased rainfall in the ocean and on the coast of West Africa as well as in Amazonia.

On the other hand, there was a decrease in rainfall in the Sahel (North Africa).

In the equatorial Atlantic there are three main cruise routes along which the ships provide climatic data, the researchers applied corrections and compared them to observations on these routes and found that in the years 1950-2009 the trade winds weakened significantly.

The warming of the water surface in the equatorial Atlantic caused changes in the climate cycle. Cold water tongues extending from the east have warmed more than the western basin. At the same time, the weakening of the trade winds reduced the rise of cold water from the depths. The cold water raises nutrients and therefore this change affects the marine fauna.

The combination of changes in water temperature and wind greatly increased the amount of rainfall, over the ocean as well as in continental areas that are adjacent to water, such as the Amazonian and West African coasts.

The researchers cite as an example the amount of rainfall in Ibadan, Nigeria: from 1950 to 2009, the amount of rainfall (in the month of August) increased by 79 mm, which is 93% of the average (perennial in August).
The researchers claim that in the last decade the differences in the changes in the ocean temperature and in the amount of rainfall have decreased, meaning fewer extreme events (?)

The researchers claim that "the warming of the ocean and the changes in the trade winds are caused by the (asymmetrical) decrease in solar radiation, a decrease caused by the effect of sprays" (emitted as a result of human activity).
The decrease in radiation is more noticeable in the Northern Hemisphere and if the emission of aerosols continues in the next decade, it is possible that in the equatorial Atlantic another climate change will occur due to the combination of the effect of aerosols and greenhouse gases. Such a change will have an important effect on the social-economic structure in the populations around the equatorial Atlantic, populations that are already suffering from global warming.

Observations and reliable information on the wind cycles in the oceans are lacking and the new research is an important tool for improving the construction of models that will allow the prediction of climatic changes under the conditions of continued global warming.

  1. A troll is a troll is a troll.
    The article does not discuss the acidity of the oceans, but as mentioned: a troll is a troll is a troll

  2. For those who are too lazy to access the reference, I brought a section as an appetizer -

    Now geologists have investigated this question further and come up with new answers. They argue, if there is such a difference between our oceans and our rivers and reservoirs then the source could not be common to both. By finding no increases anywhere in inland water systems this study has inevitably concluded that any human emissions into the atmosphere of carbon dioxide must be excluded as a potential source of oceanic acidification. The greenhouse gas theory has been under a cloud since researchers admitted there had been no statistically significant global warming for 15 years.

    And for those who are less lazy now-
    go to

  3. Is there a way to see the pictures in full?

    The link allows you to see only the abstract of the article...

  4. Dear Pediha,

    Some background on why pollution causes acid rain:

    CO2 dissolved in water forms carbonic acid
    SO2 dissolves in water forming sulfuric acid
    NO2 dissolves in water forming nitric acid.

    They are all products of industrial and traffic air pollution.
    The fact that the infections also come from volcanoes does not take away from the guilt and responsibility of man
    You are welcome to start high school chemistry before you start with theories

  5. Father, we live in the world, not in a laboratory
    This is all politics, there is no science here.

    They scare the public with some kind of boogeyman like with al-Qaeda - in order to make geopolitical changes
    The same with anthropogenic global warming - another scare tactic

    Have you heard of the Club of Rome?
    Read their document from 1993

    I imagine you won't read, but this is a successful summary of the topic:

  6. You are neither Tamir nor Ron, but the three of you receive the money and data from the same sources - conspirators. Conspirators have no responsibility, scientists do. As a matter of fact, the number seems excessive to me, I didn't have time to check it because I'm at an event but I will.
    In any case, I was under the impression that this was science fiction, and in any case, even if there are a trillion volcanoes, it shouldn't change the fact that the acidity comes from pollution because it has been proven

  7. 1. I will not convert
    2. Are you saying there is no real science?

    The study that surveyed 200 thousand volcanoes is not a real study? Why?
    Because it is not tailored to your agenda?

    But Max Power decided there were a few thousand at most.

    Who here relies on the creations of his soul?

  8. Max, whatever you say to anti-greens like Tamir won't help, he will invent science fiction because he has a problem with the real science and he insultingly demands that the real science site also rely on his creation.

  9. Commenter 3, Mr. Padiha, where did you get the figure "3 million volcanoes" does not have such an amount, a few thousand at most, and secondly the sea becomes acidic by absorbing carbon dioxide from the atmosphere and the same as the rain clouds.

  10. I would appreciate it if you could connect me
    Acid rain - emissions of pollutants - FDF

    Since when is acid rain a result of PADH?

  11. The volcanoes are to blame, so you can continue to rain acid rain as a result of pollution emissions, so as not to spend money. You might think that you have a way to evacuate to an alternate planet when you end up polluting the current one and you don't die with it.
