"Air flow from high-pressure area to a low-pressure area, but other effects resulting from the rotation of the earth modify its direction of flow. The result is that air flows anticlockwise around high-pressure area and clockwise around low-pressure areas in the southern hemisphere. (The direction of flow is reversed in the northern hemisphere.)"
I asked someone a question related to the above sentence, and he said the wind flow from north pole to equator while the earth is rotating.
If this is true, then the air flow should be clockwise in southern hemisphere since the air flow from H to L.
I also see this page in my book, http://www.scidacreview.org/0701/images/climate2.jpg
I don't know why the direction of prevailing wind is flow like this (many arrows on the earth with different directions in different layers)
I hope someone can help me out.
Thank you very much in advance.
